a21bravo do u keep the relay unplugged y u try to start the vehicle after spraying the starter fluid
a21bravo hey bro I really need ur help
Wrong again make sure you got battery voltage at fuel pump connector@ pump
2014 Chevrolet Silverado V6 my son drove the truck after the flash engine light was flashing for two days and then the truck shut off and he had it towed. I went and checked the truck out and ran a scan on the truck showed P305 and P 300. I found cylinder one and cylinder three coil packs bad so I changed all the plugs and the wires also they were fouled and very dirty and looked to be original. I checked to make sure that I was getting spark and I was. I tried to start the truck and it would just turn over with no start. I checked the mass airflow sensor and sprayed it out with mass airflow sensor cleaner. I also change the camshaft positioning sensor. Still no start. Any ideas
I tried starter fluid still no start
@@dougmorrison644Its more likely that the Fuel Pump being a wearable part would go out rather than electric suply line is compromised
Sir thank you! thank you! Thank you! Coming from a homeless man that all I have is my truck a local Mech was asking over $330 that i do not have to fix my truck and then God, sent me your Video, and it worked it WORKED!!!😂 under $5 so thank you and God bless you always Sir keep up the great work.
This video is basically saving me hours and the cost of pressure guages etc trying to troubleshoot my car, thanks for the vid.
Thank You for this video, a friend of mine just figured this out and almost spent a fortune trying to find this problem (fuel pump).
1996 Mercedes-Benz SL 320 sat for 9 years solid, didnt even try to seek faults. Just did this right of the bat and low and behold. The fuelpump was faulty... Car started up right away though on the the starter fluid after 9 long years. Thank you Sir this was really a timesaver and relief. Thank you
Yes I didn’t unplug the relay. Testing like this confirmed our opinions. Had figured it was my fuel pump..even after spending $160 for a fuel pump testing kit.. this saved us some time.
Very helpful. thanks to you 3 minutes to find out it was the fuel pump. thanks
Yep it works good,we been doing it for the last 100yrs. Fresh gas or starting fluid either one right down the old throat, it works every time.
LMAO I agree. Theirs a few tips or tricks some people should know tho. Sometimes a bad fuel pump relay etc can be fixed temporarily by tapping or reseating. And yes banging a starter while trying to crank many times does work. Saves you a tow but will not solve the problem.
I've done it on diesel automatic semis many times. Whack that think with a rubber mallet while somebody trys to start it. It'll almost always fire. Fuel Pump relays can be intermittent. Pulling it and reseating it or tapping it on ground sometimes may get that pump to start working. But again lol your still broken. Gets you to the local parts store tho with out a tow.
What he's doing is showing you hard way. Listen for a hum before turning your car to crank position. No humming. It's almost always 1 of the 3. Bad Pump, Bad Relay, Bad Fuse.
Happened to me. I tried a similar test too. My Dodge Dakota 6 cylinder ran a bit better though -- the pump (located inside the gas tank) was still working partially. Likely a clogged filter after 70 K miles! First thought it was a vacuum leak.
If you a weak pump it wont saply the fuel to the rail.
Thanx for posting this video! I'll try this out. I'm almost certain it's the fuel pump gone out on my truck. This will either confirm it or tell me to check something else on my crank, no start issue.
Wow thanks that saves me a lot of unnecessary work
Boy Oh Boy!!!! I watched all the relevant videos re engine codes/crank but no start. i changed throttle body sensors, accelerator pedal sensor and module and still crank no start....THEN came across your video and followed your advise...and ...WOW!!!!!!....it works...heaven sent....considering I'm about to give up...THANK YOU VERY MUCH!!!!!!
Glad it helped
This is the most helpful video I've ever watched with a truck different than mine. Have an 88 f250 with this issue and this video told me exactly what I need to know
Got the same shit going on with an 87 f250
This works!!! Carb vapor worked in a pinch too...
Been having this problem thanks a lot. Keep it up 👍👍
This went over so many peoples head. He took the relay out to simulate a bad fuel pump, relay, etc.
I know. Lol it's crazy how many people probably paid for a new pump when the inertia switch or relay cud be failing. Wow. Is he that ignorant or just wants to cause people extra money with bad advice ? Crazy
Yup
First thing I said crank it without touching anything 😂😂
@@karitunes1 he did it to create content a bad fuel pump can be a number of things and it’s common sense to start with the cheapest things (relay and fuses) cause they’re cheaper then a new fuel pump if you don’t understand that you should be going to a mechanic lol this was a good video
@@karitunes1 😭
your right on any car your advice helped me with a audi 17 model thanx man
Good job. Gives me a starting point.
I have check the relays or fuses On the open road it runs beautiful like a new vehicle Problems develop at low speed under 40 mph.
Mine have same problem what did you do?
Thanks Bud, saved me some time! XO
Great invention!
Thanks for the information !
awesome thanx Im workin on a 0s Audi and you right we need new fuel pump!
Great idea ! Thanks for posting
So,logical and cheap ! 👍🏻💪🏻🤞🏻
I use this process as well but it's really just a start to the Diag process as many other parts on the Fuel side or could be the issue, I wouldn't just say Bad Pump, but sometimes it is just that.
The other thing you can do is bang on the center of the fuel tank and in most cases the engine will fire. When you hit the tank the brush assembly in the electric motor will make contact again and the vehicle may start and run. I used this technique to get off of a busy street when my car died so I could get off of the main road and stop blocking traffic.
Really? Like crawl under there and just give er a bop?
@@justinswehla3793 Yes in many cases this will work for a short time. This only applies to in tank electric fuel pumps. I used a mag lite flashlight on a friends vehicle and he was able to drive home on the back roads and to the mechanic a day later to have the fuel pump repaired. You can check on repair costs in your area online with repair pal .
Oh no way that's super cool thank u for telling me that Haha I'm in a similar boat as your friend! Except mine is an older car so sadly this time I cant use the ol bop
I was wondering about that, I have been having problems with my Dodge Durango 2000, I had a very weak battery, we thought that was it, swapped in a better battery and it worked fine for like a week and then the same problem happened again, out of the blue, the engine would not start after just going into our local grocery store, I came out and it would not start, my friend banged on my fuel tank and it fired up, managed to get it home, so I guess it’s safe to say it is my fuel pump then right?
Yessiree. The absolut quickest way, and can get one out of a jam, saving a tow,. Check for a good ground @ the pump too.
Thanks for getting straight to the point
Brake cleaner works great too. Ss long as you buy the brake clean that says "Extremely Flammable " on the label. Not a lot needed and I usually crack the throttle about half way or a bit less so the spray gets by the butterfly in the throttle body.
Be very careful using brake clean. This will and can create phosgene gas which amounts to nerve Gas!
my Truck restarted after sitting for 30 minutes and Yes putting jumpers on it... Will need to check out the battery....
This only let you know your getting no fuel to the motor. It does not tell if your fuel pump is bad or not. Just that the issue is in the fuel delivery system.which is the ecm, fuel pump relay, inertia switch, tank switch in some vehicles , fuel pump(s), fuel line fuel filter, fuel pump regulated, and fuel injectors
Dont forget vvt crank and cam sensor or timing.
@@kennethcheesbrough6855 don’t forget to check for fuel even, heck that’s the first thing I’d check, I’ve seen many gm products float malfunction and get stuck on about 1/4 of a tank or even 3/4 of a tank and obviously the gauge quit…..
Thank you ,thank you I now know the problem with my no starter
By gally this guy is A genius!
Great video thanks for sharing
That's what I did to test. I have a Mercedes-Benz, and this test worked perfectly
Great to hear!
I would clarify that this only confirms a fuel starvation situation. This could be from a clogged fuel filter with a functional pump. One would have to test the pressure of the pump to verify the pump is the issue.
Most people try and replace the fuel filter before they test this.
This doesn't always mean it's a fuel pump or fuel filter I thought the same thing but after replacing everything to do with fuel the pump filter pressure regulator pump relay fuses still doesn't wanna start but wants to start on starting fluid so I'm down to either fuel injectors aren't getting a pulse or their clogged but also something else is bothering me when I test the fuel pump relay and try to hear the fuel pump prime when key is turned to the on position relay doesn't click or fuel pump doesn't prime now If I use a jump wire on relay my fuel pump runs constantly but with that jump wire with fuel pump running I checked fuel pressure from valve after the pressure regulator fuel spits out very fast so its getting fuel pressure with jump wire but won't start still so back to injectors either not getting power to pulse which since my fuel pump relay won't click when I turn key is making me think it's electrical not getting power to the relay and what powers the relay pcm or ecu are next in line for electrical problems maybe I had an electrical problem this whole time and only thought I had a fuel related problem because I did this test spraying starting fluid so just because it wants to run on fluid doesn't always mean it's fuel related and in some cases on econiline vans have are bad grounds also saw a video of a guy who showed a bad ground but mine looks good from the bottom but I lift up the plastic above where the ground lead is attached underneath van and I see a bunch of rust so I'm wondering if I have a bad ground because of all the rust
@@cheeseburgers82 did you fix fuel problem. Electrical maybe camshaft or crankshaft position sensor(s). Used the starter fluid engine did start. Thinking fuel pump bad but gas leaking around fuel pump (flange)bad o ring/ gasket.
A lot of newer cars have the filter built into the pump, how would you test that? Good fuel pump bad filter?
Did you ever find out what it was? It appears to me you have a problem with the connection of your ignition circuit to the fuel pump. Usually they don’t run together but might be closely related to the dependence of the crank shaft position sensor
GOT 2003 TAHOE,WAS
ABOUT TO CHANGE
FUEL PUMP,INSTEAD LEARNED
THAT THE (2)AMP FUSE GO BAD,
CHANGED IT,STARTED LIKE
NEW-YOUR VERY WELCOME 🙏
Gonna check this thank you
Awesome video man, thanks for sharing!
Thanks a lot
I’m on the same page with you, but how does this verify It’s the fuel pump and not like a fuel filter or wiring? Because I recently within the last year or so change the fuel pump. Now I know that doesn’t matter. I just have a 99 ram 1500 and don’t wanna drop the tank if I don’t have to. I’d like to eliminate all other possibilities first. And yes it popped off starting fluid. Thanks 😊
This exactly how mine is thanx bro
This video just helped me today thank you
Thanks and this helped me
So helpful .. thank you
2011 Chevy Tahoe LTZ 5.3 The fuel indicator is constantly changing from 1/2 tank to 1/4 or empty while driving. The dealership has diagnose it as a fail module. It seems as if every module that located in the rear has failed because of water damage
just feed sme drops of petrol in the caburator or intake for injector.. we always do that in mauritius and works great insteaf of buying this spray
this is right , as a matter of a fact when my truck stopped running and had ford garage check it a mechanic sprayed starting fluid in it almost the same way and it started , it was the fuel pump that was bad , the truck started after the starter spray was sprayed in . the fuel pump was replaced and runs good now. the reason maybe the guy unhooked the relay was to keep the truck from starting on purpose to show an example of what happens if no fuel is going to the engine , and that spraying starter fluid will help you check this type of situation. he is correct . .
How much did the fuel pump replacement cost at the mechanic? I'm thinking about pulling the bed off of my ford and replacing the pump myself.
I had a broken relay on a Chevy truck and didn't know it at the time and had to use starter fluid to start it up every time, almost replaced the fuel pump until I found out the relay was broke, so what I'm saying is that without the relay in when I sprayed starter fluid the truck would start and run and wouldn't cut out.
@@fleet39 (
Exactly what I needed to see!!!! Thanks! I have subscribed :)
I'm going to have to try this. I should spray the fluid at the end of the Intake?
Great idea, thank you!
Good video very educational.
Here's my situation my car wouldn't start.
Use starting fluid CPL times started then died. Tried one more time fired up I let car run to engines temp. Now starts again I have a manual aswell.
Any help I appreciate fuel pump going bad?
Maybe starting fluid cleaned out your egr
Probably you had a light engine flood situation. The starter fluid helped starting once. So problem "solved". ;-) EGR has nothing to do with it.
Yes it did my did the same I did what u did it happen to get it replaced from my back seat 1998 Toyota 4runner limited edition
Thanks
I tapped on the fuel tank a few times with a small hammer and my dodge fired right back up. And used a LITTLE started fluid, reason being I've heard of engines getting ruint if you spray to much
cool I am having weird random non starting problem on my f 150 next time it acts up i will try this, at least it will narrow things down my mechanic cannot duplicate the problem.
Exactly what we did with my Smart 4/2.. with stuck fuel pump. It had a crank / no start. Worked. And pump is replaced.
Good job
Word of Caution!!! If the car backfires you can catch the car on fire. Best to use the carburetor cleaner sparingly and have a fire extinguisher at the ready!!! Caught my Yukon on fire today.
Mine caught on fire just a few days ago and i was scared as hell. Luckily i was able to turn it off😂
Thanks it really helped me
Nice! Thanks for the feedback.
I needed you to show me the relay was out just once more.
According to the comments half the team didn't understand why I pulled it. So I should have showed it 47 more times apparently, lol.
Thank you for that its just how mine is .I though fuel pumps had gone down but not sure ...but now i am 😀😀
So what about no start but starts with starting fluid and will continue to run fine until shut off?
ok here is a good one....same scenario same symptoms almost dropped the tank off my truck (2001 f150) to replace fuel pump. problem..................I was using a spare aftermarket key that the truck would not recognize so it would cut off the fuel system. The kicker is that sometimes it would work fine it just would not always accept the key.
That sucks but very good that you figured it out! That could have got real expensive if you replace parts as a form of troubleshooting like some ppl do. 👍
My problem is intermittent and occurs when I shut the car off between 30 seconds and 5 minutes. After 5 minutes it always starts. How do you know the difference between a bad fuel pump and a bad fuel pump relay?
Thank you
Thank You
I had a bad fuel injector in cylinder 5. I got that taken care of. Before that I had the fuel filter changed. After the fuel filter was changed, the car started sputtering and will die out once it warms up. Is this caused by the fuel pump?
Thanks again
Before I change the fuel pump..... I have followed all your trouble shooting advice (short of using a pressure gage). I can hear the fuel pump when the key is turned over to accessory it sounds strong and when my wife turns the key over it does not sound as strong. To be sure, should I spend the money on a pressure gage? Thanks for a great video.
Men obviously can just turn the key strongly and given that universal fact pump runs strong, unlike women using machine causing dainty pumping by dainty key turning with feminine energy contaminating manly machine.
There's a lot more it could be besides the pump. Filter, pressure regulator to make a couple
A CRANK NO START does not always mean a bad pump, you also have to check the basics SPARK, FUEL, AIR COMPRESSION as well, short to ground is the ecm commanding the fuel pump on when the key switch is turned on.
But, this video is about fuel related causes, not the others... Even though this method does verify spark and compression (If it fires with starting fluid)
Well he obviously ruled spark and air if it starts but does his video mean its the fuel pump not necessarily i like to think of it of starting the investigation in the right direction ruling spark and air and focusing on fuel like pump relay short in the wire to the pump etc…
🤡🤡🤡🤡🤡🤡🤡🤡🤡
Easy way to check as suggested by ATG & me:
1. Required two people.
2. Open the gas cap
3. Turn key to #2 but do not start the car
4. Place ear next to gas lid & listen to the fuel pump making a sound
5. If you can hear the hum sounds, then rule that pump is good.
6. You replaced that Fuel Filter ever 3 years? Open output hose & input into 1 gal milk & start
Or you can jump the relay or hook a 9v battery direct to the file pump if it's accessable
What if the 25.00 cam sensor is bad. The cam sensor is the main input for the injectors. A fuel pump module can run 3 to 400.00. Using starting fluid only tells you if you are or aren't getting fuel in the cylinders. Remove timing and compression questions. I use starting fluid as one diagnostic tool. Not the only one.
Will an OBD reader pick that up?
Pick up if the cam sensor is working?
Short answer ...yes. cam sensor codes are P034x or on the 0340 to 345 range. So if there is a fault, it might.
Yes, there is a BUT.
Sometimes the sensor is intermittent or barely within parameters and it won't set a code. So the diagnostic steps I use are
1. Starting fluid
2. Pressure test fuel system
3. Noid light to check injector circuit.
These steps will give you a picture of what's happening.
did you check the inertia switch? It could be bad?
Well I am going to attempt to try this. Maybe it will work or maybe it won't. Let's do this......
Leslie Hunt Good luck... Remember it doesn't fix problem but helps diagnose a no fuel situation. Let me know how it goes.
Thanks, that helps narrow down the problem.
It actually doesn't. All he did is remove the relay to simulate a bad fuel pump. It can be inertia switch, relay or loose wire before assuming it's a bad pump
So what does it mean when you do this and it actually runs but then stops running after you turn it off and let it sit? Then doesn't even start running after you try this again?
Mines is made the same way gmc 5.3 the starting fluid made it backfire. It was only driving when cold and cuts off when warm
Hey same happening with my mercedes w204 can u help its just cut off when hot then needs to get cold to start
that describes my 2001 ranger to a T. When the weather is warm, it starts just fine. Once we get cold temps, it will only start if I use starting fluid. but once it starts, it runs just fine. Is my fuel pump really the problem? The fuel pump must be pumping fuel once it starts running because it doesn't die.... Any ideas would be greatly appreciated! FYI, I have replaced the fuel filter.
I use this method as a diagnostic tool on a petrol engine to check if the ignition system is working, it 'could' help in diagnosing a bad fuel pump ? But it's not a hard and fast diagnosis that 'you have a bad fuel pump' there's a few more variables of what could be wrong ..... great video though 👍👍
Paul Parsons Correct. A good indicator engine is not getting fuel. Thanks for watching.
Thisw 2works ok as an early test. It proves that you have spark. It eliminates that entire system. How ever it only proves that the fuel system is not working. Mor4e testing needs to be done to prove what fuel component is the malf. Many things can cause the pump not to run.
Yes but the first thing you check is the relay/fuses start the cheapest is that doesn’t fix it then you replace the fuel pump assembly it’s cheaper and easier
@@chancesmall7026 how do you do this? I replaced the relays but still nothing, I don’t hear a click when the car is in the on position like I use to
@@Francofit you need two people to be able to do this trick one needs to lay down in the trunk with your ear against the inside of the trunk, have someone in the car, don’t start the car up but turn the key over all the way. Whoever’s laying in the trunk should hear a sound if you do your fuel pump is fine if not it’s something else. What’s wrong with your car might be able to help
@@chancesmall7026 my car won’t turn on anymore, I bought the new relay for it but nothing, it starts with starter fluid but then it dies right after, I tried hearing a click while someone starts it but nothing, I also can’t hear the click anymore inside like I use to when i put it into the on position
@@Francofit yea it’s most likely your fuel pump bud im sorry but just in case check your fuel filter first it’s a lot cheaper and sometime they get clogged up, also buy some Lucas oil fuel injector cleaner/fuel system cleaner try get it started and run some of that through it. If that doesn’t work it probably is the fuel pump I’m sorry
Is there anything else that can cause no fuel pressure at the fuel rail?
I bought a 84 old pontiac. It wont start. I spray a bit of starter fluid and it will start right away. I could drive around for 10 min. Shut off the engine and the car will start again just fine. It seems to only need starter fluid when the engine is cold. I changed spark plugs already. Any suggestions?
So I have a fule delivery problem listening to utube i changed the crank position sensor in a 2004 mitsubishi outlander sport 2.4l I've pulled the fule pump in the bottom of the pump canister was what looked like mud so I cleaned is and whats next to do any suggestions
I have a relay that didn't work in extreme cold. You can jumper them.
How
@@dustinbowls8887 unplug the bad relay, get a small jumper wire or paperclip and jump the two connections.
for my car, it's the top two on the left of the plug
my fuel pump relay just died on me again so I've had to do that a few times
This video is going to save me a thousand atleast.
See i used starting fluid and it did just that. I didn't have this problem until my altenator went bad. Very rarely but sometimes it starts normally without a problem but rarely.
Pls advice what is durability of diesel fuel pump vw polo
Or it could be injection, pressure regulator, fuel filter, pinched or broken fuel line. Or you could just be out of fuel.
WD-40 a bit safer than starting fluid.
to my surprise it works well on 4 stroke gas engines.
Diesel? not so much on cold start, but it helps & leaves a little lube that ether [starting fluid] removes.
Thanks au biggin
What does it mean after you spray starter fluid and the engine runs but, doesn't shut off until you turn the key off?Every time I turn the key off, I have to use starter fluid.
2006 Impala 3.9 automatic 4 door.
Awesome video. Thanks a lot.
It can be multiple things actually. Mine is doing that right now but my fuel pulp turns on and my car will run until you shut it off then there is no power to it anymore. Last time my car wouldnt start and wasnt getting any fuel it was because of my egr. It can be many problems, it can also be getting vapor locked from the canister.
Just to add on to this, make sure no fuel line is touching anything hot. If you you can use a hanger to space it off of the heat. It can make it vapor lock. Check all sensors not just the relay. Make sure your fuel filter is not clogged as well and that there are no tears in your wiring.
Be careful not to use too much starter fluid, especially when the engine is not cranking while spraying the fluid. My son literally blew up his intake manifold.
@walker.wayne5772
The fact is I did warn my son to go pretty sparingly on the starter fluid. But he had other ideas, as sons sometimes do...
Yup, my Air filter and housing blew right off the car. Did not realize it was too much starting fluid !
@@bhagyawanbhagat2361
Starting fluid should come with a predominant warning label on the can.
Your not 100% right, what you have determined is that you have a fuel delivery problem. Corroded injector harness, blown fuse controlling injector, harness at fuel pump and a few others. Describing it this way may lead DYI’s on the wrong path and pull tank , put new pump in and still no start. Starting fluid , as others have said may not be good if used incorrectly, get air intake cleaner or injection cleaner, less volatile but still combustible to achieve what your describing and greatly reduces accidents
My brother does this all the time with my used cars. It seems I buy them just before fuel pump goes out lol
miriam deltoro same😂😂
My ranger wont start and I did this and it fires up for a sec or 2 then stalls out. Any chance it could be something other than the fuel pump?
Thanks for the video man, although you're getting a lot of flak from some ignorant people.... they probably pour the milk before the cereal.
Carb cleaner also works as starting fluid
This is true... Another good way to test is with a multimeter
i use the top of a flexible straw wd40 on a starter fluid can that way i can twist and get it inti the intake
