I used to be a diagnostic specialist and you are exactly right about the parts cannon. The reason I got out is because the guys firing the parts cannon doing it wrong made a lot more than I did. I had to have advanced tooling and know what I was doing....all they had to do was throw parts at it and get paid for their labor. Customers don't want to pay for it to be properly diagnosed until the parts cannon is out of ammo....then they didn't want to pay me because they already spend all their money on ammo. I gave up on trying to change human psychology. This truck is a perfect example. I will guarantee that the knowledge and skill it took to figure this abortion on wheels after 20 people molested it, either paid less, or got absorbed into the bill to change the injectors. The better you are at diag....the less you make. But you'll have broke customers and cars lined up out the door, as long as you are willing to work for less than the guy pulling the trigger on the parts cannon. He's still getting paid labor and parts on every misdiagnosis....or nondiagnosis.
Charge more per hour (2-3x) and tell the customer to get it back from those who did not fix it. A skilled surgeon gets paid more than a primary care physician ( a lot more) who writes prescriptions.
Hi Ivan, I laughed so hard, when you read one of the customer's note where he says, please be patient and do not get frustrated with the truck if you can not fix it. Great work Ivan. I got to tell you, after my clutch was changed, P0615 error came up on my Honda civic 2006 and 3 months and 5 different mechanics later, one Ukrainian electronics repairman finally resolved it. I was a bad fuse and relay. Thanks.
The proliferation of fake , counterfeit parts is extremely disturbing to this old time retired car tech. I know it’s in other fields as well. Anyone guess where this will end ?

@@johnbragg2014 It’s a vicious cycle. No one wants to buy a part made by someone making $30/ hr when they can buy “identical looking part” made by someone making $30/week. Then we wonder why brake rotor warps in a month, bolts fall out of starter or blower motor makes cheap bearing noise. Even buying from dealer no longer guarantees quality USA made parts ☹️
This series was particularly interesting to me because my own 2010 Silverado 2500 had a similar symptom. There's nothing to gain from cheap parts! Unfortunately Ebay and Amazon seem completely uninterested in keeping counterfeit parts off of their platforms. I've had a LOT of issues with this generation of GM Injector too. When they are exposed to air for extended periods of time, they'll get stuck closed. You can use the old hammer to knock em into life but they're never right after that.

Great videos Ivan!
@@I_Do_Cars hey Eric! Yeah man I love these pre-GDI non-AFM LS trucks! When something does break they are super easy to diagnose and repair, even with new OEM parts 😁👌 Sadly people still find a way to butcher them lol
@@gadasavideos8564 yes. I wouldn’t worry about harder to replicate parts like hoses, and heavy mechanical… but coils, plugs and injectors 1000% would avoid from eBay or amazon.
I did a 5.3 swap in my 94 s10. Motor I used ran fine when I pulled it out of my donor. It sat around for about a year and a half before I installed it in my S10. It was showing the same symptoms as this truck was showing. I have access to a salvage yard so I grabbed a bunch of complete duel rails with injectors. Rigged up a bench tester and ran cleaner through each injector. Went through three whole fuel rails with injectors to get 8 that worked the way I wanted. Truck runs great now and I have good OEM parts.
Great Video! On my 1995 E-150 Club Conversion Van (350,000 miles) I was having a hard start when warm, smelled flooded. I heard all about the fake injectors of the web. I bought a set of rebuilts (cleaned and new o-rings) now I have to watch my speed in the old beast! Just love your can do never quit ability inspires me when I feel like quitting. Mike
I loved this video and that customer deserves some praise for giving you all of that history. He was at wit's end, and in the end, helped his own cause. Which probably saved him some money after all he went through to make it to Ivan. I can guarantee that he is a fan for life. I've seen you do some wonders fairly regularly since I started watching you and subscribed a few years ago. Big fan! Keep up the good work! It's rare to see someone who can break it down and fix it with all of the complexities in the modem day vehicles and make it look easy with how you arrive at your diagnosis and repair. We should call out these car companies and boycott their products if they won't let us have access to repair them. Like formerly Chrysler and now almost bankruptcy stellantis
@@frankd.brennan6520 thank you for the kind words, Frank! It is truly a blessing that I get to help people every day and then share these diagnostic adventures with everyone too! 🙏😊
Glad I stayed for bonus footage because now you have landed squarely with what my truck is doing. Replaced the cam sensor with a 'genuine cam sensor' from RockAuto but still have the multiple start problem when hot issue. I will now continue watching for what I hope is a solution to my problem as well as what was most likely the customers original complaint. Btw, I too verified fuel pump pressure and leak down and both were perfect.
@aciddiver1978 That's a challenge, but he increasingly seems to have folks traveling impressive distances in some cases just to tap into his expertise. This guy's a rock star.
Back in the day aftermarket was as good as or better than OEM. That was back when the aftermarket manufacturers made ranked quality slightly above profit.
Great video! I learned as a teenager working at a gas station with two repair bays. I had an old drag racer from the 60’s as a boss that worked on the cars. He told me to always replace a part with genuine GM, Ford or Chrysler parts and hang on to the old part for a while. I have always maintained my cars with quality parts and thank goodness I have never had a crazy scenario like this. I have seen countless guys be pennywise and dollar foolish and get burned by cheap knock off parts.
I've got this same model truck but only 10 years older. After watching some of these videos, I count myself lucky to only have run into minor maintenance repairs. Had the engine rebuilt at 277k Everything works great. Wife wanted me to buy a new truck. I said no thanks. lol.
"New" and "better" got a quietly arranged non standstill agreement starting a few decades back thanks to computerized design being able to give quality an ever "closer shave". As Lee once said way back about Japanese cars, "Building a $20k car and selling it for $13k is not rocket science (if the exchange rates are in your favor)".
Boy do I know what you mean. I own two trucks, a 1994 F150, 4.9, 2wd 5 speed manual, and a 2004 F150 5.4 4wd. I did a complete timing job on the 5.4 at 153k the 94 has never needed much of anything. I can afford a new truck, but Frankly, I don't want anything they are building today.
It looks like dealers and shops are all ok in reading codes, that lead to replacing parts. Not so much in reading live data, and correct interpretation of the foodback.
@smileyspeedster you are exactly correct except for the food back (feedback). While they're smart enough to read codes, it doesn't necessarily direct them to solve the primary issue.
I had a similar issue long ago in my 04 Sierra, when I went forced induction. When viewing your scan data in the 1st vid, my thought was the injectors, especially when you mentioned the alcohol content and PW . Lean fuel trims; coming off idle, coasting going fat. In the end, I was given the incorrect injector data and my PW adder and minimum injector or dead times were off. Company sent the right data and corrected the values in the tune, ran good after that. Great Job Ivan!
I am waiting for the fellow who commented in the last video re his guess that it was a fuel problem to chime in and now admit he was wrong. I wonder how long Ivan will need need to wait for that. On the other side, Ivan was willing to keep investigating, at his own cost, why the long crank start after the 15 min heat soak. Plus he was man enough to show the issue and then show what he did to check it - several times. I have watched Ivan's videos for some time now and his values and ethics are first class. His knowledge is not bad either. His diagnostic skills are way above mine. Retired mechanic in Land Down Under.
@@_RiseAgainst I think the customer would rather have a proper guaranteed diagnosis. He paid $10K for s parts cannon based on other sorts of assessments.
Ivan, I believe your hypothesis is correct on the initial hot soak starting issue. Since the fuel rail was completely emptied of fuel, it is still possible to have trapped, pressurized air (and fuel vapor once fuel is introduced) in the fuel even after the car is started…the vapor headspace is simply compressed to the same pressure as the fuel. Will work itself out quickly. Purging the fuel rail of air at the Schraeder valve after completely emptying the fuel rail of fuel will eliminate this symptom.
@@PineHollowAutoDiagnostics most likely. And another paradox…measuring something without changing the state of what you are measuring. Not always possible.
Two very frustrating problems from back in the ‘80s… Poor quality testing of OE Chrysler alternators (whole batches were defective) and a spark plug manufacturer that dumped tested/defective plugs into an unsecured dumpster and someone repackaged and sold. After massive complaints both issues were investigated and corrected, thankfully. I expected this kind of thing was finally resolved but couldn’t anticipate the Chinese knockoff market. I shop and bite the bullet for critical parts.
Did I see in the opening credits of this video that the customer doesn't think I can repair his truck? Really? As you correctly stated, Ivan, this was a seemingly straight forward diagnosis and quite simple R and R of the injectors. Your shirt didn't even come off for this one! GREAT VIDEO!
I want to thank you for publishing this video I have a 2 thous and 12 Silverado 2500 a lot of the same exact issues.I made some minor repairs like plugs wires and coil packs which made no difference. Toy saved me alot of money and time . Thank you again 🎉
Hey dude. I wanted to suggest something in the last video but waited until part 2. I was going to recommend that you do a dynamic MAF sensor test. It's a trick I picked up diagnosing early 2000 models VW Jettas. You want to have the vehicle cruising about 40 mph with light throttle and light engine load. Then mash the accelerator to get the calculated engine load as close to 100% as possible. The MAF sensor reading at 100% calculated engine load should easily read above 100 g/s. With the value increasing based on the displacement of the engine. I like to go as a guide that four-cylinder equals 100, 6 cylinder equals 150, and 8 cylinder equals 200. And as you notice on your scan data reading doing your wide open throttle run mass air flow sensor eclipse just over 200 g/s. It's not an exact and official diagnostic method. However it can quickly determine whether or not you should look at the breathability of the engine. Because if it's not able to read the values I indicated there's only a few possibilities in my experience. Which would be a restricted exhaust, restricted intake. A faulty or incorrect MAF sensor, or an issue with the power, ground wires to the sensor and/or signal wire between the sensor and PCM. One final cause of a low mass air flow sensor reading could also be that the engine is just completely wore the f out. But as you know, an engine vacuum test should determine that in short order.
You fixed this fast because of your vast experience, expertise and skill. Please charge appropriately, I get issues in my business that people think it should be cheaper because they should pay by the hour, I say sure do you want me to let the young newby do it next time?.., he will take a lot longer so you get your ‘moneys worth’.., though I can’t guarantee he’ll do as good a job as me 😂
This truck uses the L96 which is probably peak LS from a truck perspective. No AFM but does have variable cam phasing. I wonder what the original issue was at 300k, if it really needed a new engine.
I agree with you about NEW parts from ebay, however they did come to my rescue with a USED TIPM for my 2014 Dodge Grand Caravan, at $ 300! A new OEM unit was over $1200 , and not readily available.
Hooray! Great diagnostic and repair, Ivan! It's fixed with no hidden problems - that glitch was just a bit of stage fright from the new injectors 🙂 It seems fake parts are an even bigger problem than crappy aftermarket parts - if price seems too good to be true, it probably is.
I have a 97 1500 with the 350. My mechanic kept putting fuel pumps in it. He was warranty them but I could keep affording the tow bill. I got a new Chevy fuel pump from Chevy. No more problems.
Sometimes with older vehicles even dealer parts can have issues since if still available they have been sitting for a long long time. Especially electrical parts. Glad you got it sorted though!
We had an older vett (later 2000's I think) come in bc could smell raw gas outside the car. Kid next to me traced it down to cracked fuel line coming out of the pump. BUT, R&R pump module called for 11 hrs bc had to drop entire drive train and rear subframe/suspension. Got an AC Delco pump because of the time involved. He got everything back together, pump was bad out of the box, wouldn't even sustain 10psi...... shop ordered a Delphi, car runs great...
@@brianmason8400 Delphi pumps are not as good as they once were. We put one in a 97 GMC truck and replaced the fuel filter at the same time and the tank was clean. 11,000 miles and about a year and a half later, it went out. It had a lifetime warranty so we put in another one but who knows how long it will last.
I've seen that exact scenario probably 100 times over the last 20 years, GM has had the same fueling system right down to the assembly hat rusting since the 1990's. Nothing worse than a customer bringing you Chinesium parts, ironically GM is all Chinesium now.
Im truly impressed with your skills. I to have installed Chinese injectors from amazon and similar issues. Went to dealer and bought genuine GM injectors and all runs fine.
Hi Ivan, good video. I was wondering if you had an air lock in the injector rail, since there is no return line to the tank there is only one way for the air to get out and that is though the injectors. Rich
I had injector fail in a 03 dodge 3500.rather than spend 4k on good injectors i put a 94 12 valve with a governorspring ,fuel plate and mac plug tweek.Pull stop cable.I can bump start it with no batteries....luv it. Gotta commend you on your knowledge and perserverance.Valuable commodities these days.
Can't believe how many workshops simply guesses and replaces parts without doing any type of investigation. This was so simple. The moment you eased up on the gas pedal and the fuel trims went from +30% to double digit minus, my mind went straight to bad injectors. I am not even hard core at this diag stuff, but this was so obvious. But hey, let's just keep replacing the fuel pump and hope that problem goes away before the pumps goes into back order.
Some things haven't changed. I started pulling wrenches in the 70's. We all wanted to go faster back then and found out those aftermarket parts just did not hold up.
Yep, the owner should put as much of the OEM parts back as he can. I bet those Chinese "racing" coils won't last long, and if he bought eBay or Amazon plugs they are likely just the cheapest garbage that will wear out in 10k miles.
I see others have commented on the crap parts that are out there. It's so aggravating that companies only care about the dollar and not quality. Great work on your part and I appreciate that you film these episodes so we can all learn.
What pisses me off is the stealership did all that testing & did not do a fuel leak down test which would have given them the same direction you went & the other private shops the same comment ,because after you took it on a test derive I was confident it was injector related.Cheers Ivan.
The last time I considered firing the parts cannon was a fuel issue on my 02 F250 V10. But with 10 $120 injectors I just couldn't take the shot. But in the end it was a fuel pump that only failed under load, I'm talking parking brake fully engaged and wide open throttle before the pressure dropped to 15psi. And that truck went through 2 fuel pumps in 6 months because the filler neck rotted out after the first pump replacement and rust, winter road sand etc got into the tank and ruined the pump. With a 34 gallon tank and fuel pumps only going bad with a nearly full tank, yes I cut an access hole in my fiberglass service bed. It was cheaper than buying 6 5 gallon gas cans.
Nice work, Ivan. As another commentor mentioned, parts quality has become an issue lately. You have to be very careful what you buy, and from who. Keep up the great work.
I have this exact truck, however mines a 2013 that I bought used from an auction. Mines a flat bed with a fifth wheel. I paid $5500 and it said “as is” …. Needless to say that was a hell of a deal for the truck however even though the seller told me it ran great I noticed a miss off the bat. It would start hiccuping and backfiring, and then the next minute it would run great again. I threw the parts cannon at it and bought all brand new sensors, fuel pump, wires, injectors, coils, etc etc etc! Had it diagnosed by 3 different shops, needless to say 3 shops couldn’t give me a guaranteed answer, just costly speculations… I ended up going through it over and over and was ready to scrap it and on a hunch I checked temp on my catalytic converters and 2 were clogged so I deleted them, then it ran better but still far from perfect and I noticed my brand new “Bosch” 02 sensors weren’t switching like they should be, so I put in ac delco and that truck has ran like a damn top ever since, another issue i fixed at the same time was a kinked fuel line whenever they put in the flat bed they pinched it between the tank and the frame. Besides having 220k on the dash, id send your grandma off to church in it on Sunday without a worry in the world. Moral of the story when I seen orange ignition coils i automatically thought cheap Chinese and how many other parts did he replace already. I’d start by putting back all original parts before doing a diagnostic. The way they replaced the fuel pump 5 times gots me wondering if he’s having the same issue I was with a kicked fuel line or an aftermarket 02 sensor. My truck will ONLY regulate fuel the way it should with the OEM 02 sensors
Well, the ending was disappointing for me but it does make me wonder about a couple things. I got the truck after it had been parked for more than a year. Several attempts at cleaning the injectors only resulted in a mild improvement. I got a full set of 4 hole rebuilt injectors out of Florida and after installation the truck ran as well as the one you have there. BUT, when it was hot and sat for usually more than 15 minutes, it would do the same thing, take usually two but sometimes three attempts to start. Sometimes after it did start, it will act like it doesn't want to run but then comes alive and runs perfect till the next shutdown. Since the cam sensor is known to act this way, I replaced the cam sensor but with no change in its behavior. Mine is a '02 so it has a regulator and return system, so it does leak down over a period of time. Now I'm wondering if possibly I have a leaking injector because of your comments. Thanks for your time making these videos, I'm sure it takes much more time with your repairs in doing these.
I admire, on this particular repair, how you just disconnect the MAF without any real concern on a customer vehicle. Having written ECM fuel control strategy I would never be this brave. I would actually put a scope on the MAF sensor output and gather data (correlate to the PID readout) before I would disconnect the sensor and attempt to run the engine. I admit it, you can call me a MAF disconnect wimp. The speed-density algorithm is usually written well as an emergency backup but the overall closed loop fuel control can be a little skewed with some strange control loop phase (time delay) problems. In the dyno and emissions lab the engineers will spend a great deal of time mapping the engine and fine tuning the MAF strategy, while the speed-density portion is given a cursory evaluation in comparison relying mostly on the basic vol-eff 3D table.
I guess the computer has parameters it needs to fill in. The boss explained it to me years ago and said think of it as a large square grid with hundred of little squares stacked on rows with each other and in columns with each other. Well, those got to get filled in with good info I bet. Sometimes it helps to, or you may even have to, do some learning procedures for different things. Well done Ivan. Excellent. I will call you #2, next to that Eric O fella. Not bad. Not bad at all. :)
I had the same problem with my 2010 Silverado after many trips to the dealer, and the problem not solved they went to GM engineers . The problem was to replace one of the valve covers. So far so good after one year !
Parts cannon is often how things are done in the aircraft industry because there are usually severe time pressures (troubleshooting at the gate, or in the hangar on a machine that must fly in 6 hours to avoid flight cancellations costing 10s of thousands of dollars) and they just don't want to put in the time troubleshooting. So many problems are caused by water ingress to electrical connectors or insulation breakdown on harnesses. I would get called and after hearing they were throwing parts at it, I'd say "did you megger the harness?" (ie, meg-Ohmmeter checks that detect insulation breakdown, or moisture induced cross talk) and they'd say no, go do it, and end up changing a wiring harness. I love working on my own airplane. Updraft carburetor, two mags for ignition, alternator and starter, no sensors of any kind for the engine itself (just cyl head temp and ex gas temp to the cockpit gauges). It's like working on a car from the early 60s.
I used to make the fuel injector housings on a machine called a hydromat. I can think of many steps that an unscrupulous manufacturer could take to cut costs.
From my experience with changing injectors (besides not buying from Ebay😬), on the few I have worked on. If you experience a "glitch" on the initial start up, give it a few cycles to iron out any anomalies that might occur because you are dealing with empty injector rails, lines, etc..... Nice work, as usual, Dr. Ivan! 👍
Hey Ivan there is a middle ground. I had a intermittent starting problem. Mechanic could not replicate. I found a video you did and replaced master relay so for shiggles and to avoid another tow replaced the master relay. No issues since then so copying your work helped a lot so far:)
This video is a trained diag man doing what he is trained to do 🎓 Imagine that🅰️ Other shops take notice that's how you make money and gain loyal customers 💰💰💰💰💰💰💰💰 Great video💪👍
The guy brought all the extra cost on himself 😂😂 Great job as always Ivan 👍 U should of bet him he pays double. He so sure of himself you can't fix the truck...
Great diag once again data driven accurate diagnosis. Been watching Ivans vids for a couple of years now as well as Bernie and S M Auto all i can say is how good youtube and these guys are to share their knowledge and techniques. I was thinking incorrect fuel injectors after Bernie Thompson had similar issues on one of his epic diags. Anyway counterfeit rubbish again with scam packaging . I find usually in life if things look too good to be true they usually are not . Trying to save some $$$ is fine but if the parts are extremely cheap the alarm bells should be ringing. Hopefully the owner learnt a good lesson from his cheap parts cannon repair fiasco.
You are right Ivan i bought a set of inyectors for my Avalanche a while ago from ebay and was a disaster and ended up cleaning the old ones and is running lake a champ,,
Awesome video. Really surprised no one else figured that out. SO SIMPLE. But stumped so many. About 1/2 way thru I was like HAS to be FI's. BTW how do you like that scanner? Does it work for all cars? Will it reset the tailgate ECU's on a 2019 Silverado. I had a similar hot soak hard/no start issue with a 4.3MPI Mercruiser in my boat. Turned out to be the Fuel pressure regulator at the end of the fuel rail. It was dirty and allowing the pressure in the rail to drop after shut down and in the hot engine compartment I got vapor lock. The fuel system doesn't return to the tank but returns to the filter on the side of the engine.
My guess in the first video was off! You made the excellent call in regards to the fuel injectors. I should never assume things are factory pieces. People using non factory parts is crazy unless they take the full responsibility for doing so. Excellent call, got my sub!
first of all- I'm not in love with you Ivan- lol- even though it wouldn't be so much of a bad idea- 😂- I made a RUclips video tribute to you- it's in my RUclips channel- you just deserve that and more- it'a a 16 minutes video with me talking and I little system of a down music- this tribute to you was made here in Caracas Venezuela- the Land that will soon be free- here in Venezuela, well, we also like to study and work to earn our money- well, stop politics and get back to you Ivan- thank you bro-
The owner MAY want to change where the fuel is bought. I've seen problems in the past with "cut rate or off brand" fuels, but generally the branded gas stations are good. I know they're more expensive, but "you get what you pay for." Good one Ivan!
That's a nice looking truck including the color! This repair proves what a PITA counterfeit or cheap parts can be. All is not lost however. The customer has plenty of fuel pumps!
Another job well done. I can't understand how people think they can diagnose any problem without theory of operation and not reading the manual. Ivan knows me and my primary job is computer networks and network trouble shooting. That said if you use logic and do a little reading and your research you can diagnose most things. Maybe not as fast as others but it can be done. I was asked to look at a metal detector at the school district where I work. It was showing a battery error message on self test. Read the manual open the machine where the battery module lives. BINGO found the charge cable unplugged, Plugged back in turn the detector on no error. Battery showing 14% charge. The end users states see it's using 14% of the battery. I showed them in the manual that was show how much charge was left in the battery. As a wise Master Sgt in the Air Force taught me. R.T.F.M! READ THE F*ING MAUAL.!
I just replaced the front 3 fuel injectors on my lexus rx300 with amazon specials. $75 for 6. The misfire on cylinder 4 is now gone and its running normal again, but this video gave me a real eye opener to fake parts and and the frustration it could lead to.
you are a rare mech you understand how things work electrically and mechanically had a interesting problem with injectors 1 injector was bad flowing to much fuel bought a set of injectors from amazon 1 injector was bad flowing to much fuel found out if you can blow thru the injector like a straw you can know that injector is bad
I had a Buick brought to me that a shop gave up on. The customer bought a tps and a maf sensor both off rock auto , he bought the cheap parts and both were bad. The other shop assumed they were good because they were new. We have to always test , not guess all parts because we are getting scammed every day.
I used to be a diagnostic specialist and you are exactly right about the parts cannon. The reason I got out is because the guys firing the parts cannon doing it wrong made a lot more than I did.

I gave up on trying to change human psychology. This truck is a perfect example. I will guarantee that the knowledge and skill it took to figure this abortion on wheels after 20 people molested it, either paid less, or got absorbed into the bill to change the injectors.
The better you are at diag....the less you make. But you'll have broke customers and cars lined up out the door, as long as you are willing to work for less than the guy pulling the trigger on the parts cannon. He's still getting paid labor and parts on every misdiagnosis....or nondiagnosis.

@COBRO98 I see what you did there! If you know, you know.
I did a 5.3 swap in my 94 s10. Motor I used ran fine when I pulled it out of my donor. It sat around for about a year and a half before I installed it in my S10. It was showing the same symptoms as this truck was showing. I have access to a salvage yard so I grabbed a bunch of complete duel rails with injectors. Rigged up a bench tester and ran cleaner through each injector. Went through three whole fuel rails with injectors to get 8 that worked the way I wanted. Truck runs great now and I have good OEM parts.
Uninstalling Ebay parts certainly keeps you busy and us entertained.
Great Video! On my 1995 E-150 Club Conversion Van (350,000 miles) I was having a hard start when warm, smelled flooded. I heard all about the fake injectors of the web. I bought a set of rebuilts (cleaned and new o-rings) now I have to watch my speed in the old beast! Just love your can do never quit ability inspires me when I feel like quitting. Mike
I have to quit on my projects as I broke my middle finger yesterday.😭
I loved this video and that customer deserves some praise for giving you all of that history. He was at wit's end, and in the end, helped his own cause. Which probably saved him some money after all he went through to make it to Ivan. I can guarantee that he is a fan for life. I've seen you do some wonders fairly regularly since I started watching you and subscribed a few years ago. Big fan! Keep up the good work! It's rare to see someone who can break it down and fix it with all of the complexities in the modem day vehicles and make it look easy with how you arrive at your diagnosis and repair. We should call out these car companies and boycott their products if they won't let us have access to repair them. Like formerly Chrysler and now almost bankruptcy stellantis
@@frankd.brennan6520 thank you for the kind words, Frank! It is truly a blessing that I get to help people every day and then share these diagnostic adventures with everyone too! 🙏😊
Glad I stayed for bonus footage because now you have landed squarely with what my truck is doing. Replaced the cam sensor with a 'genuine cam sensor' from RockAuto but still have the multiple start problem when hot issue. I will now continue watching for what I hope is a solution to my problem as well as what was most likely the customers original complaint. Btw, I too verified fuel pump pressure and leak down and both were perfect.
If you want to be frustrated and waste money, take your vehicle anywhere. But, if you want it fixed right, absolutely, Ivan's your man.
I would definately, if i lived nearby.
@aciddiver1978 That's a challenge, but he increasingly seems to have folks traveling impressive distances in some cases just to tap into his expertise.
This guy's a rock star.
It’s a 39 hour drive for me. 😂😢
Well, 39 hours is too far.....
Or just keep telling yourself, what would the Russian do?
After watching your videos, i never use anything but original parts when it comes to sensors, modules, injectors, engine parts.
Back in the day aftermarket was as good as or better than OEM. That was back when the aftermarket manufacturers made ranked quality slightly above profit.
Good call. You can get away with aftermarket pads, rotors, suspension parts, etc. But when it comes to electronics, stick with OEM when you can.
On a tight budget, I'd rather chance it on a salvage yard part than an Amazon "OEM" deal.
Great video! I learned as a teenager working at a gas station with two repair bays. I had an old drag racer from the 60’s as a boss that worked on the cars. He told me to always replace a part with genuine GM, Ford or Chrysler parts and hang on to the old part for a while. I have always maintained my cars with quality parts and thank goodness I have never had a crazy scenario like this. I have seen countless guys be pennywise and dollar foolish and get burned by cheap knock off parts.
I've got this same model truck but only 10 years older. After watching some of these videos, I count myself lucky to only have run into minor maintenance repairs. Had the engine rebuilt at 277k Everything works great. Wife wanted me to buy a new truck. I said no thanks. lol.
"New" and "better" got a quietly arranged non standstill agreement starting a few decades back thanks to computerized design being able to give quality an ever "closer shave". As Lee once said way back about Japanese cars, "Building a $20k car and selling it for $13k is not rocket science (if the exchange rates are in your favor)".
Boy do I know what you mean. I own two trucks, a 1994 F150, 4.9, 2wd 5 speed manual, and a 2004 F150 5.4 4wd. I did a complete timing job on the 5.4 at 153k the 94 has never needed much of anything. I can afford a new truck, but Frankly, I don't want anything they are building today.
I miss my old GMC 3/4 ton work truck-no A/C, crank windows, and rubber floor. It wasn't my daily, but it did everything a pickup should do well.
It looks like dealers and shops are all ok in reading codes, that lead to replacing parts.
Not so much in reading live data, and correct interpretation of the foodback.
@smileyspeedster you are exactly correct except for the food back (feedback). While they're smart enough to read codes, it doesn't necessarily direct them to solve the primary issue.
These twos videos just reminded me why I like old cars and trucks with carburetors and no computers!
Amen!
@@martinsuter3531 definitely less ammo needed for the parts cannon haha
As long as it gets driven daily otherwise you have to deal with ethanol screwing up the carb and having to prime the system if it's mechanical pump

Im still kinda shocked ROck Auto offered those injectors for 40$. great 2 video set Ivan
rock auto does not have the rip off middleman, aka the stealership.
They also charge for shipping. eBay doesn't sometimes.
I had a similar issue long ago in my 04 Sierra, when I went forced induction. When viewing your scan data in the 1st vid, my thought was the injectors, especially when you mentioned the alcohol content and PW . Lean fuel trims; coming off idle, coasting going fat. In the end, I was given the incorrect injector data and my PW adder and minimum injector or dead times were off. Company sent the right data and corrected the values in the tune, ran good after that.
Great Job Ivan!
I am waiting for the fellow who commented in the last video re his guess that it was a fuel problem to chime in and now admit he was wrong. I wonder how long Ivan will need need to wait for that. On the other side, Ivan was willing to keep investigating, at his own cost, why the long crank start after the 15 min heat soak. Plus he was man enough to show the issue and then show what he did to check it - several times. I have watched Ivan's videos for some time now and his values and ethics are first class. His knowledge is not bad either. His diagnostic skills are way above mine. Retired mechanic in Land Down Under.
Technically, it WAS a fuel problem: not enough of it. XD
@@farmermiyagi1338 Only other guy said it was NOT an injector problem.
@@bobhudson6659 Ah, I must have missed that comment. Don't mind me too much, I'm a bit of a snark in the morning. ;)
That's why you keep your

@@_RiseAgainst I think the customer would rather have a proper guaranteed diagnosis. He paid $10K for s parts cannon based on other sorts of assessments.
Great part 2 video here. Love the diagnosis and correct steps to repair Ivan!
Ivan, I believe your hypothesis is correct on the initial hot soak starting issue. Since the fuel rail was completely emptied of fuel, it is still possible to have trapped, pressurized air (and fuel vapor once fuel is introduced) in the fuel even after the car is started…the vapor headspace is simply compressed to the same pressure as the fuel. Will work itself out quickly. Purging the fuel rail of air at the Schraeder valve after completely emptying the fuel rail of fuel will eliminate this symptom.
@@reneneron2971 yes I think when I hooked up the fuel pressure gauge that purged the vapor pocket 😊👍
@@PineHollowAutoDiagnostics most likely. And another paradox…measuring something without changing the state of what you are measuring. Not always possible.

Two very frustrating problems from back in the ‘80s… Poor quality testing of OE Chrysler alternators (whole batches were defective) and a spark plug manufacturer that dumped tested/defective plugs into an unsecured dumpster and someone repackaged and sold. After massive complaints both issues were investigated and corrected, thankfully. I expected this kind of thing was finally resolved but couldn’t anticipate the Chinese knockoff market. I shop and bite the bullet for critical parts.
What you do makes everyone happy. Thanks for helping that guy.
What a great video! I appreciate you walking SLOWLY through the diagnostics especially the data screens, down to the fuel trims and why.
Did I see in the opening credits of this video that the customer doesn't think I can repair his truck? Really? As you correctly stated, Ivan, this was a seemingly straight forward diagnosis and quite simple R and R of the injectors. Your shirt didn't even come off for this one! GREAT VIDEO!
I think somebody who worked on it previously suspected the injectors, but thought "the injectors are new, so that can't be the problem!"
They came from ebay that should be a red flag lol
I want to thank you for publishing this video I have a 2 thous and 12 Silverado 2500 a lot of the same exact issues.I made some minor repairs like plugs wires and coil packs which made no difference. Toy saved me alot of money and time . Thank you again 🎉
Hey dude. I wanted to suggest something in the last video but waited until part 2. I was going to recommend that you do a dynamic MAF sensor test. It's a trick I picked up diagnosing early 2000 models VW Jettas. You want to have the vehicle cruising about 40 mph with light throttle and light engine load. Then mash the accelerator to get the calculated engine load as close to 100% as possible. The MAF sensor reading at 100% calculated engine load should easily read above 100 g/s. With the value increasing based on the displacement of the engine. I like to go as a guide that four-cylinder equals 100, 6 cylinder equals 150, and 8 cylinder equals 200. And as you notice on your scan data reading doing your wide open throttle run mass air flow sensor eclipse just over 200 g/s. It's not an exact and official diagnostic method. However it can quickly determine whether or not you should look at the breathability of the engine. Because if it's not able to read the values I indicated there's only a few possibilities in my experience. Which would be a restricted exhaust, restricted intake. A faulty or incorrect MAF sensor, or an issue with the power, ground wires to the sensor and/or signal wire between the sensor and PCM.
One final cause of a low mass air flow sensor reading could also be that the engine is just completely wore the f out. But as you know, an engine vacuum test should determine that in short order.
Ivan, you need a folding workbench to save your knees and back. You deserve the best.
You fixed this fast because of your vast experience, expertise and skill. Please charge appropriately, I get issues in my business that people think it should be cheaper because they should pay by the hour, I say sure do you want me to let the young newby do it next time?.., he will take a lot longer so you get your ‘moneys worth’.., though I can’t guarantee he’ll do as good a job as me 😂
This truck uses the L96 which is probably peak LS from a truck perspective. No AFM but does have variable cam phasing. I wonder what the original issue was at 300k, if it really needed a new engine.
2500s don't have AFM derp
@@samholdsworth420 Isn't that what I said?
we were waiting for part 2 👍👍👍👍
I agree with you about NEW parts from ebay, however they did come to my rescue with a USED TIPM for my 2014 Dodge Grand Caravan, at $ 300!
A new OEM unit was over $1200 , and not readily available.
There is a company MAK’S in Chatsworth, CA that remans TIPMs and stand behind their work.
Hooray! Great diagnostic and repair, Ivan! It's fixed with no hidden problems - that glitch was just a bit of stage fright from the new injectors 🙂
It seems fake parts are an even bigger problem than crappy aftermarket parts - if price seems too good to be true, it probably is.
Great diagnosis and investigation, Ivan. Thanks as always!
I have a 97 1500 with the 350. My mechanic kept putting fuel pumps in it. He was warranty them but I could keep affording the tow bill. I got a new Chevy fuel pump from Chevy. No more problems.
Sometimes with older vehicles even dealer parts can have issues since if still available they have been sitting for a long long time. Especially electrical parts.
Glad you got it sorted though!
We had an older vett (later 2000's I think) come in bc could smell raw gas outside the car. Kid next to me traced it down to cracked fuel line coming out of the pump. BUT, R&R pump module called for 11 hrs bc had to drop entire drive train and rear subframe/suspension. Got an AC Delco pump because of the time involved. He got everything back together, pump was bad out of the box, wouldn't even sustain 10psi...... shop ordered a Delphi, car runs great...
@@brianmason8400 Delphi pumps are not as good as they once were. We put one in a 97 GMC truck and replaced the fuel filter at the same time and the tank was clean. 11,000 miles and about a year and a half later, it went out. It had a lifetime warranty so we put in another one but who knows how long it will last.
@@Mr2004MCSS well, hopefully,all again bc of the labor time involved, it lasts awhile....
I've seen that exact scenario probably 100 times over the last 20 years, GM has had the same fueling system right down to the assembly hat rusting since the 1990's.
Nothing worse than a customer bringing you Chinesium parts, ironically GM is all Chinesium now.
Im truly impressed with your skills. I to have installed Chinese injectors from amazon and similar issues. Went to dealer and bought genuine GM injectors and all runs fine.
Murphy made a brief stop by your shop on his way up to spend time with Eric.
Ivan, thank you for producing your videos, logic and proper deduction is not a given for a lot of people, keep on preaching OEM parts.
Hi Ivan, good video. I was wondering if you had an air lock in the injector rail, since there is no return line to the tank there is only one way for the air to get out and that is though the injectors.
Rich
Nice work!!! Enjoyable to see logical diagnosis of repairs.
I had injector fail in a 03 dodge 3500.rather than spend 4k on good injectors i put a 94 12 valve with a governorspring ,fuel plate and mac plug tweek.Pull stop cable.I can bump start it with no batteries....luv it.
Gotta commend you on your knowledge and perserverance.Valuable commodities these days.
9:22 I saw the traction light blink on the test drive and thought the bonus footage would have been about a reduced power issue. 😂 Good job, Ivan!
Can't believe how many workshops simply guesses and replaces parts without doing any type of investigation. This was so simple. The moment you eased up on the gas pedal and the fuel trims went from +30% to double digit minus, my mind went straight to bad injectors. I am not even hard core at this diag stuff, but this was so obvious. But hey, let's just keep replacing the fuel pump and hope that problem goes away before the pumps goes into back order.
Great job! I really enjoy getting the jobs others couldn't fix. Working on old fuel injection systems, I get them often but that's fine by me.
Some things haven't changed. I started pulling wrenches in the 70's. We all wanted to go faster back then and found out those aftermarket parts just did not hold up.
Yep, the owner should put as much of the OEM parts back as he can.
I bet those Chinese "racing" coils won't last long, and if he bought eBay or Amazon plugs they are likely just the cheapest garbage that will wear out in 10k miles.
@@volvo09 You can almost guarantee those PRC coils won't last 10,000 miles
I see others have commented on the crap parts that are out there. It's so aggravating that companies only care about the dollar and not quality. Great work on your part and I appreciate that you film these episodes so we can all learn.
Come to think of it, probably every Chevy 2500 owner who uses the Chinese injectors has problems with the engine.
That's what happens when the bottom line is the only line.
Which companies? E-bay, amazon? Or the counterfeit china parts makers?? Who are you mad at???
It might be time to start an annual award/trophy for the parts cannon firing of the year.
Great diagnoses and repair! Fun video. Thanks
@7:31, as Eric would say, whoa Chevy thunder!
What pisses me off is the stealership did all that testing & did not do a fuel leak down test which would have given them the same direction you went & the other private shops the same comment ,because after you took it on a test derive I was confident it was injector related.Cheers Ivan.
I learn so much from watching you Ivan!
The last time I considered firing the parts cannon was a fuel issue on my 02 F250 V10. But with 10 $120 injectors I just couldn't take the shot. But in the end it was a fuel pump that only failed under load, I'm talking parking brake fully engaged and wide open throttle before the pressure dropped to 15psi. And that truck went through 2 fuel pumps in 6 months because the filler neck rotted out after the first pump replacement and rust, winter road sand etc got into the tank and ruined the pump. With a 34 gallon tank and fuel pumps only going bad with a nearly full tank, yes I cut an access hole in my fiberglass service bed. It was cheaper than buying 6 5 gallon gas cans.
Nice work, Ivan. As another commentor mentioned, parts quality has become an issue lately. You have to be very careful what you buy, and from who. Keep up the great work.
I have this exact truck, however mines a 2013 that I bought used from an auction. Mines a flat bed with a fifth wheel. I paid $5500 and it said “as is” …. Needless to say that was a hell of a deal for the truck however even though the seller told me it ran great I noticed a miss off the bat. It would start hiccuping and backfiring, and then the next minute it would run great again. I threw the parts cannon at it and bought all brand new sensors, fuel pump, wires, injectors, coils, etc etc etc! Had it diagnosed by 3 different shops, needless to say 3 shops couldn’t give me a guaranteed answer, just costly speculations… I ended up going through it over and over and was ready to scrap it and on a hunch I checked temp on my catalytic converters and 2 were clogged so I deleted them, then it ran better but still far from perfect and I noticed my brand new “Bosch” 02 sensors weren’t switching like they should be, so I put in ac delco and that truck has ran like a damn top ever since, another issue i fixed at the same time was a kinked fuel line whenever they put in the flat bed they pinched it between the tank and the frame. Besides having 220k on the dash, id send your grandma off to church in it on Sunday without a worry in the world. Moral of the story when I seen orange ignition coils i automatically thought cheap Chinese and how many other parts did he replace already. I’d start by putting back all original parts before doing a diagnostic. The way they replaced the fuel pump 5 times gots me wondering if he’s having the same issue I was with a kicked fuel line or an aftermarket 02 sensor. My truck will ONLY regulate fuel the way it should with the OEM 02 sensors
great diag as usual, you have so much more experience than most shop mechanics, ur savy know how will out, thanks for posting
Thank you for sharing your expertise and diagnosing a vehicle thank you for your knowledge also
Well, the ending was disappointing for me but it does make me wonder about a couple things. I got the truck after it had been parked for more than a year. Several attempts at cleaning the injectors only resulted in a mild improvement. I got a full set of 4 hole rebuilt injectors out of Florida and after installation the truck ran as well as the one you have there. BUT, when it was hot and sat for usually more than 15 minutes, it would do the same thing, take usually two but sometimes three attempts to start. Sometimes after it did start, it will act like it doesn't want to run but then comes alive and runs perfect till the next shutdown. Since the cam sensor is known to act this way, I replaced the cam sensor but with no change in its behavior. Mine is a '02 so it has a regulator and return system, so it does leak down over a period of time. Now I'm wondering if possibly I have a leaking injector because of your comments. Thanks for your time making these videos, I'm sure it takes much more time with your repairs in doing these.
You and Eric are the best at what you guys do. Absolute blast to watch and learn.
Few use their brains and logic.
Now it’s time to replace those POS aftermarket coils.
I see a lot of pats cannon's fired, with cheap junky parts store parts. So many time they introduce more problem with the after market parts.
The owner should be smart and reinstall all the OEM parts he still has his hands on.
Lol. It's really satisfying when you get through with a diagnosis that has been around the world.
Another outstanding video and diagnosis. Thanks Ivan
I admire, on this particular repair, how you just disconnect the MAF without any real concern on a customer vehicle. Having written ECM fuel control strategy I would never be this brave. I would actually put a scope on the MAF sensor output and gather data (correlate to the PID readout) before I would disconnect the sensor and attempt to run the engine. I admit it, you can call me a MAF disconnect wimp.
The speed-density algorithm is usually written well as an emergency backup but the overall closed loop fuel control can be a little skewed with some strange control loop phase (time delay) problems. In the dyno and emissions lab the engineers will spend a great deal of time mapping the engine and fine tuning the MAF strategy, while the speed-density portion is given a cursory evaluation in comparison relying mostly on the basic vol-eff 3D table.
I learn so much watching your show! Saving up for a pico and transducer.
Good job on correct diagnosis.
I guess the computer has parameters it needs to fill in. The boss explained it to me years ago and said think of it as a large square grid with hundred of little squares stacked on rows with each other and in columns with each other. Well, those got to get filled in with good info I bet. Sometimes it helps to, or you may even have to, do some learning procedures for different things. Well done Ivan. Excellent. I will call you #2, next to that Eric O fella. Not bad. Not bad at all. :)
Fascinating video as always... Thanks. Keep them coming.
I had the same problem with my 2010 Silverado after many trips to the dealer, and the problem not solved they went to GM engineers . The problem was to replace one of the valve covers. So far so good after one year !
@@Mannyarruda-d6i how could replacing a valve cover solve this problem? 🤔
Getting data is simple. Interpreting it is a whole different game.

Great job and nice video. Appreciate what you do !
Parts cannon is often how things are done in the aircraft industry because there are usually severe time pressures (troubleshooting at the gate, or in the hangar on a machine that must fly in 6 hours to avoid flight cancellations costing 10s of thousands of dollars) and they just don't want to put in the time troubleshooting. So many problems are caused by water ingress to electrical connectors or insulation breakdown on harnesses. I would get called and after hearing they were throwing parts at it, I'd say "did you megger the harness?" (ie, meg-Ohmmeter checks that detect insulation breakdown, or moisture induced cross talk) and they'd say no, go do it, and end up changing a wiring harness. I love working on my own airplane. Updraft carburetor, two mags for ignition, alternator and starter, no sensors of any kind for the engine itself (just cyl head temp and ex gas temp to the cockpit gauges). It's like working on a car from the early 60s.
OEM on injectors and fuel pumps is a must. Good video broham 👍
Even I feel like I'm a winner when I watch Ivan! Great job. I agree, a bit of vapor, maybe injector needed to seat-re-seat.
I used to make the fuel injector housings on a machine called a hydromat. I can think of many steps that an unscrupulous manufacturer could take to cut costs.
Good video. I've gotten junk parts from Rock Auto too. I go to the dealer now.
Going the extra mile Ivan,good going Ivan,peace of mind Ivan,can’t beat it,doing your best is the way to go,
From my experience with changing injectors (besides not buying from Ebay😬), on the few I have worked on. If you experience a "glitch" on the initial start up, give it a few cycles to iron out any anomalies that might occur because you are dealing with empty injector rails, lines, etc..... Nice work, as usual, Dr. Ivan! 👍
Hey Ivan there is a middle ground. I had a intermittent starting problem. Mechanic could not replicate. I found a video you did and replaced master relay so for shiggles and to avoid another tow replaced the master relay. No issues since then so copying your work helped a lot so far:)
Great job Ivan! I had a knee-jerk reaction to the long crank after heat soak, the 'super' fancy red coils! Blasted counterfeit parts!

Great diag once again data driven accurate diagnosis. Been watching Ivans vids for a couple of years now as well as Bernie and S M Auto all i can say is how good youtube and these guys are to share their knowledge and techniques. I was thinking incorrect fuel injectors after Bernie Thompson had similar issues on one of his epic diags. Anyway counterfeit rubbish again with scam packaging . I find usually in life if things look too good to be true they usually are not . Trying to save some $$$ is fine but if the parts are extremely cheap the alarm bells should be ringing. Hopefully the owner learnt a good lesson from his cheap parts cannon repair fiasco.
Chevy thunder ⛈️ 😊
You are right Ivan i bought a set of inyectors for my Avalanche a while ago from ebay and was a disaster and ended up cleaning the old ones and is running lake a champ,,
What a great channel. I'm glad I found it. Thank you.
Awesome video. Really surprised no one else figured that out. SO SIMPLE. But stumped so many. About 1/2 way thru I was like HAS to be FI's. BTW how do you like that scanner? Does it work for all cars? Will it reset the tailgate ECU's on a 2019 Silverado. I had a similar hot soak hard/no start issue with a 4.3MPI Mercruiser in my boat. Turned out to be the Fuel pressure regulator at the end of the fuel rail. It was dirty and allowing the pressure in the rail to drop after shut down and in the hot engine compartment I got vapor lock. The fuel system doesn't return to the tank but returns to the filter on the side of the engine.
I have never bought any car part from flea-bay and this is a great example why...
My guess in the first video was off! You made the excellent call in regards to the fuel injectors. I should never assume things are factory pieces. People using non factory parts is crazy unless they take the full responsibility for doing so. Excellent call, got my sub!
first of all- I'm not in love with you Ivan- lol- even though it wouldn't be so much of a bad idea- 😂- I made a RUclips video tribute to you- it's in my RUclips channel- you just deserve that and more- it'a a 16 minutes video with me talking and I little system of a down music- this tribute to you was made here in Caracas Venezuela- the Land that will soon be free- here in Venezuela, well, we also like to study and work to earn our money- well, stop politics and get back to you Ivan- thank you bro-
The owner MAY want to change where the fuel is bought. I've seen problems in the past with "cut rate or off brand" fuels, but generally the branded gas stations are good. I know they're more expensive, but "you get what you pay for."
Good one Ivan!
Ebay and Amazon got to crack down on sellers who sell fake / counterfeit parts
That's a nice looking truck including the color! This repair proves what a PITA counterfeit or cheap parts can be. All is not lost however. The customer has plenty of fuel pumps!
Please come to Brooklyn or SI, Ivan.
I have something right up your alley. ;) Can’t seem to figure it out for a year already.
Another job well done. I can't understand how people think they can diagnose any problem without theory of operation and not reading the manual. Ivan knows me and my primary job is computer networks and network trouble shooting. That said if you use logic and do a little reading and your research you can diagnose most things. Maybe not as fast as others but it can be done. I was asked to look at a metal detector at the school district where I work. It was showing a battery error message on self test. Read the manual open the machine where the battery module lives. BINGO found the charge cable unplugged, Plugged back in turn the detector on no error. Battery showing 14% charge. The end users states see it's using 14% of the battery. I showed them in the manual that was show how much charge was left in the battery. As a wise Master Sgt in the Air Force taught me. R.T.F.M! READ THE F*ING MAUAL.!
RTFM and RCA (root cause analysis) should get you about 95% there.
I just replaced the front 3 fuel injectors on my lexus rx300 with amazon specials. $75 for 6. The misfire on cylinder 4 is now gone and its running normal again, but this video gave me a real eye opener to fake parts and and the frustration it could lead to.
I wouldn't trust those long-term at all haha
you are a rare mech you understand how things work electrically and mechanically had a interesting problem with injectors 1 injector was bad flowing to much fuel bought a set of injectors from amazon 1 injector was bad flowing to much fuel found out if you can blow thru the injector like a straw you can know that injector is bad
I had a Buick brought to me that a shop gave up on. The customer bought a tps and a maf sensor both off rock auto , he bought the cheap parts and both were bad. The other shop assumed they were good because they were new. We have to always test , not guess all parts because we are getting scammed every day.
Beautifully done ✔️
Nice work as always Mr. Ivan.
