ANOTHER GM Crank No-Start?? (GMC Sierra V6)
HTML-код
- Опубликовано: 2 окт 2024
- Kind of fitting that the first and last diagnostic calls on this Ohio road trip are GM vehicles that cannot START!
This 2006 GMC Sierra V6 was running rough a month ago and then just died.
Owner replaced the Distributor Cap, Rotor, Spark plugs and Wires, but no joy...
Let's see what we're missing, and pinpoint the root cause of the no-start with NO GUESSWORK.

Thanks Ivan. Kind of refreshing to see a full-sized truck with a basic naturally-aspirated V6 (and a manual). Now *that* is a truck.
It may be a 2006 but that's a straight up 90s fuel/ignition system. Not saying that's a bad thing.
Wait till you see the previous video with a 08 Buick running the 3800 using an even older ignition system that dates back to the late 80s.
Simple yet effective.
Yeah, wow, I had no idea they did that so late. The thing looks like it was ripped out of a TBI engine.
Yeah. As soon as the video started I said. It needs a control module. That’s basically all that ever went bad on those systems other than the cap and rotor.
I have a known good test pair of those coil and module that I just plug in as a quick test to verify and it saves me lots of time. Great diagnosis Ivan! Thanks!
This is a great channel for those of us who want to sharpen our diagnostic skills. I always learn something, watching this channel. Keep up the great work, Ivan.
U look tired on the road ivan.Good job !!!!....work safe!...God bless u & the Mrs. !!!!
Ivan knows I am a GM guy. That system was used on a lot GM V6. I kept a spare ICM in a Blazer I owned after getting stranded once when it died. Saved my butt several times. Nice work my friend.
Looks like something I'll need to grab at pull a part to have in my glovebox then.
GM Guy huh, ... Iikes being abused and having your wallet lightened unnecessarily eh?
@@CedroCron GM has made the most consistently reliable vehicles from about 1960 to 2010. I get why people are fans. They have betrayed those fan recently, but what manufacturer hasn't?
@@_RiseAgainst 😂😂😂 Thanks... Needed the laugh. "Consistently reliable vehicles from 1960 to 2010" ... Really. Might want to check actual scores on reliability done by various consumer groups. Then there is the bailouts they needed remember that "too big to fail". Also I can tell you what has rolled through our doors at our shops consistently is broke down GM's, Fords and Chryslers in that order. Same quality problems leading to the same repeated failures over and over again for years upon years in some cases. Don't make me list all the failures GM is known for. I'd be here all year explaining their poor quality in so many areas.
@@CedroCron well I can't argue with your anecdotes and all these consumer reports that span 50 years which you have memorized.
Another, on-the-fly, accurate diagnostic 🙂 That ICM was probably failing for a while, before it finally died. Good job, Ivan!
Ivan, great job diagnosing that truck. Also great to know it is fixed and on the road again. Hope you're enjoying the road trip. Thanks for Sharing! 🙃🙂
It dont take u long to figure out whats wrong. Great channel
I bet it took at least an hour.😮 Not to mention driving there, making sure he left home with all the right tools, setting up the appointment, dragging out a fuel gauge, an oscilloscope, a laptop, a scanner, untangling the test leads, finding the owners house, checking the oil, reading the codes. Then verifying his own diagnosis by checking wires and pins. Professionals make it look easy
I've a feeling Ivan has seen a few of these in the past.
A bad ICM, on a GM? ... No, can't be. LOL ... Good job Ivan!
That was a very smooth and efficient diagnosis, great work!
Ivan fuel Spark run Best diagnose steps in action ,,Thanks
It's nice to see a thorough diagnose and verification without guesses, again and as always, Ivan!
Awesome combination - Ivan and an oscilloscope.
I wish that some other RUclipsrs would be as straight to the point as you Ivan! Too much talka- talka just to get to the point. I usually fall asleep
half way through their videos. Another great video Ivan, thank you!
Bravo.
Saved some expensive dealership repairs.
At the City Fleet, we had several of the GM mini vans with the 4.3L V6. They were great except when the intermittents appeared in 2 of the vans. Using my old Fluke Scope, I was able to narrow it down to the Ignition Module like Ivan did here. The intermittents took a lot of time to zero in at the ign module, and the driving did help. The scope had a small "Record" memory, but it worked well.
Good one Ivan!
I've seen the pink or the white wires break internally, at the module or coil. Is a common problem with that ignition system.
4.3 v6 bad fuel injection spider or fuel regulator....had one in a chevy S10 Blazer ......rebuilt the entire system
Imagine your car setting for a year over an i.c.m when you actually replaced everything in the ignition system , except the i.c.m lol.
(fac) Obviously, the Oil change did it!
Hy Toyota Corolla 1.3L s maf is over reporting .I change maf but didn't fix.why maf is at 3g/s instead of 1.6g/s.plz fuel trims -30
I suspected a clogged fuel system as soon as you started giving the symptoms.
You eliminated that real quick.
That's why they pay you the big bucks. 😂😅😂😅 😊😊
I had a code W S-10 Blazer that would stall pulling out of toll booths unless I counted 1,2. It did this from day 1. 60mph+ to complete stop if you went back on the gas in less than 2 seconds stall. They replaced the spider 4 times under warranty. Then 4 other mechanics knowing the history and so sure that would fix the problem didn't get paid. 8 spiders from the lot to the junkyard. 160k NEVER RAN RIGHT.
My Astro had two problems in its 280000 miles. One, fuel pump at 147000 miles and ignition module at 205000 miles. Amazing how certain technologies fail at about the same time.
i had one of those and its damp where i live, always had a spare rotor button and cap. change it twice a year until i traded it.
Crank on 10:45, is the cylinder wash or..
The coil must've been 'for good measure'... ;)
Very thorough diagnosis Ivan!
those control modules cause all kinds of problems when they go bad...acts just like bad fuel pump...i have a few older GM vehicles and i keep an extra on my parts shelf..
People dare question the master
For an 11 minute video, it has to be out of gas :-)
😂
@ 10:45 ----> what is "AHAMAY" ?? 🤣🤣🤣
Ivan, Love it brother the way u approach this truck problem even without WIRING diagram JUST BY COMMON SENSE thanks for sharing cheeeers.
Hello Ivan im a new follower here im wondering how do I get in touch with you, regarding pricing on a job. Its a no crank no start on a 2007 Cadillac Escalade I saw your video with Jasons Escalade so I ordered a new computer for the truck says it won't be to me for another 2days I have been watching all of your other videos and I love what you do and how you handle things 😎 im located in Detroit MI and would love to speak with you due to me knowing that I need your help.
@@tolbertkraig website Appointment form 👍
I have an 1994 S10 blazer with the 4.3 first gen. I can't remember off top of my head if that's the X or W 4.3 code. The ground on the ICM was crappy and it kept eating modules. Mine is under the cap though. Moved the ground and haven't had to replace one since. ;)
Sounds like a cat scan after 10:26
Diagnosis: I'm hungry
1996?
I have an 03, it's a 4.8 liter, with 437k miles

From Nick Ayivor from London England UK 🇬🇧 ⏰️ 13:03 Good Afternoon
I like the way you home in on that stuff! I like that truck, too! 2 doors, shifter in the floor..... Mmmmmmm!
Not really my 05 1500 gmc truck had 4.3 I put a 67 mm turbo to make up for loss in power I went pretty good
You count percentage just like tRump, the last check put it to 100% sorry there is no 150% to make you sound like you went the extra mile.
Lol
WTF...
WHERE DID THE ENGINE GO...😮😂
As an electronic engineer with literally zero experience with working on cars, I love your videos! There are certainly similarities between your diagnostic work and the debugging work I do on electronic circuits.
What I genuinely wonder is why I see so many V6s and V8s in your videos, while the majority of the cars in the road have only 3 or 4 cylinders.
Very good Ivan. This again proves as you keep saying, you need to know how the system works and of course homework and wiring diagrams. May I ask, will you ever do a fix on anti collision Lidar.
Yep, gotta use oem electrical parts. Which I have to assume will get tougher sourcing oem parts as time passes, especially on low volume vehicles including most EVs.
Super slick diag. Thanks Ivan!
That seems to be a fairly common failure item on those engines. I had a customer come in once with an old astro van. Crank, no start. He told me he went to start it and heard a loud explosion. Sure enough, coil and igniter are shot. After I replaced them and got it running, I found out what went boom. The muffler had exploded and ripped wide open. It was the craziest thing I ever saw.
Bottom line, always change your engine oil when changing the ignition module🙂
Whenever its a module, you usually replace it. Isn't it often something simple inside that can be repaired, or do they degrade beyond repair?
There is no opening up those little ignition modules on these, just toss and replace. Pretty common failure on this style.
usually they are potted or coated, at least in the engine compartment, my jeep heater control panel lights went out, something like $100 for module, I replaced the light, had it in my junk box.
Modules like this are often " potted" meaning the circuit is built and tested ok, then a resin is poured over the electronic parts to help resist moisture and vibration- induced failures. The unit is then permanently sealed. Digging potting off components is very difficult. So no, component repair is unlikely
A rare combo indeed V6 and a 5 speed manual most of that generation you'd see on the road are autos.
I'm curious what the gap on the old sparkplugs looked like. Might have killed a module by not changing them sooner.
Those darn GM's 😃
19 years old, 150k, simple repair.
Back when an ordinary person could afford to buy a new truck, regular cab, manual transmission, V6 engine, hand crank windows, vinyl bench seats, rubber floor.
@@jamespn And you didn't need to program every nut and bolt to the vehicle.. God I miss all of that.
Fuel pressure? Its that time of year where fuel pumps die.
Replaced a few of those.
It's gotta be nice to get the ocassional easy one.... (Concidering that it's mostly 'troubled child' stuff that comes your way)
always do the distributer cap and rotor as well on those.
Yamaha t shirt, nice sir
👍
RU OK Ivan, you look tired in this one.
@@johnt.848 this was after the crazy Blink 182 concert 😂
@@PineHollowAutoDiagnostics oh good to hear, I was worried.
Good.
Bought new I have a 97 S10 LS extended cab 4.3 rear wheel drive, in the 26 years I had to replace the water pump alternator battery and tires of course and I rebuilt the front end upper and lower control arms etc. The only trouble I had starting it was when I replaced the cap and rotor with non Delco parts, I used the best of the best from advanced and when it rained and for days after it wouldn't start, thinking there was something wrong with the new components i went back and they gave me new ones under warranty, the same thing happened, I went on the line and did some research and found a guy with the same issue, he replaced the cap and rotor with genuine Delco parts and never had the problem again, i said it couldn't be that simple but it was worth a try, advanced carried the Delco, i replaced it and problem solved.
OEM for the WIN!
Considering the owner changed out many parts before you were involved, after he got it restarted - did that slight hesitation disappear that he had for years
He said that the hesitation got a lot better, but there might be another issue 🤔
10:23 Awesome
Ivan on top of the game as usual. 💪
Gotta love the easy fixes !
My God, I hate the parts cannon. Can you imagine how many hrs less people would have to work if they used their minds?
Nice work Ivan.
Great video as always... And respect on the Yamaha top I saw glimpses of!
I swear by my Yamaha motorcycles ;)
AHAMAY in the screen reflection
Looks like the owner wasn't doing any testing just throwing parts at at it .
He basically replaced the entire ignition system...except the coil and ICM haha
Those ignition parts that were replaced before the diagnosis had 70000 miles from me and not sure how many from previous owner. They were due.
CPI leaky fuel rail "spider assy" was fixed by 1998, surely by 2006. I had a 1995 blazer S10 4.3 Liter vortec V6 that i gave up on because we had to lift the intake up once a year to install a new fuel rail. our ignition module died too. I put a non-ACdelco after market module in. I gave up and finally gave it to my mechanic, had to tow it there..BOY OH BOY!! i will never forget the tongue lashing that salty old Navy Veteran mechanic gave to me for putting the cheap ignition module in.😅
I'm 99% sure my 2000 sonoma still has the old poppet valve spider system. It does not idle well with ethanol fuel.
Nice video Ivan.
Could have figured that out in less than 10 minutes
thanks for the insights
Nice
Morning, sir!
Ivan, did the owner also change the ignition coil in case it was shorted which could have killed the module?
@@agostinodibella9939 yes as I mentioned in the last slide 😉
Good morning Ivan!
Good morning! 😁
$180 for an OEM ICM. This has pull-a-part run written all over it.
Why would you buy a junk electronic part that's doomed to fail? Might be good to have as a spare
@@privateer0561 because I can get 10 used oem ones for the price of a new one.
Edit: maybe 20. GM used this same ICM on 100s of vehicles
Ha I see the problem
does that sound like a bad hole as well when cranking? 10:45
probably washed out from the injector test, it sounded fine earlier
Ivan, did you eat at Skyline Chili while in Ohio?
Where is that located?
Yes, and they comped his meal because he fixed their delivery van before his meal came out.

The LIKE and DISLIKE THUMB is missing on my screen. Is anyone else having this issue? I think it is hiding behind the gray box where it shows the view count.
no
Still on my iPad.
Perfect here.
Didn’t even realize an 06 still had this system. Evidently they were still failing. 👍👍🇺🇸
Whoa! which system? the crappy " high energy" ( as it was called) ignition system, or the leaky central port fuel rail system?
@@pootthatbak2578 Both.
@@brianw8963lol😅
Seems to be the same song and dance with these GMs. Just saying.
It seems that Holden did away with an engine which is that old in 2004 which is the 3.8 litre Buick L36 V6 engine.
I know that the engine in the video is a Chevy V6 & not a Buick but in Australia they were using the 3.6 litre litre GM global V6 engine 20 years ago.
GM were still using the Buick L36 V6 engine up until 2008 in the U.S., Holden stopped fitting those old engines for emission control reasons in Australia.
It's like in New Zealand they ceased manufacturing leaded fuelled vehicles in 1996 which was a decade after in Australia they made it mandatory for every brand new vehicle to be made to run on unleaded fuel !
GM took a while to shovel the High Feature V6 into Colorados and Canyons, I think. Cost a fortune to make compared to this pushrod donkey 4.3 l 90 degree V6. Why they made both this thing and the Buick 3800 for years is beyond my ken. GM is beyond my ken. The GM board let that idiot Wagoner lose $70 billion in stock value between 1999 and 2007. Then flat out bankruptcy happened. Anyone ever heard what became of the man who blew GM to smithereens?
As for what happened in Australia and NZ that nobody cares about, sorry, here's another now useless factoid. The EU didn't fully have unleaded fuel availability and cats and a set of pollution regulations until 1992. 1975 in North America. Of course, to listen to Europeans, you'd think they invented all the green stuff, because they have marvelous selected memories.
