Chevy GMC Engine Cranks But Wont Start 

Tim, that was a heartfelt prayer and sentiment. The information on the fuel pump was well said. I'm certain you are a blessing to your community. Peace brother

Thanks Tim. This failure seems pretty common on these trucks. I had the same issue twice on my 98 Chevy.

A heart felt thank you from a nurse 💙

My 07 Silverado would just shut off going down the road. The first time I had to get it towed to the mechanic and they could find anything wrong with it. I had just replaced the fuel pump 4 months before just because it has 160,000 miles on it. So I was pretty sure that was not the problem. Mean while it died on me on the freeway two times in under 10 miles but restarted. My brother came into town who is a good mechanic and we looked at everything and it would not repeat itself until one day outside Harbor Freight were we had just bought a fuel pressure gauge it would not start. So we put the gauge on and no pressure, waited like 30 minutes and it started. I then decided to try my Chevy dealer and they said the fuel pump was bad, so I had then replace it. Just under $700. And a few days later it would not start again. When it did decide to start I ran down to the dealer right before closing and pulled into service bay and then one of the service techs went to move it and it would not start. So the service writer now could hear the problem since she was only a few feet away. So one of the things my brother looked at was the fuse block under the hood, but he did not have the tools with him to check it out. End of story it was the fuse block. Guess when it would get hot it would expand and loose contact with the fuel pump relay. Moral of the story check out that fuse block under the hood before spending $$$$ on a fuel pump. And my dealer did give me a good discount on the second go around.

Thanks a thousand, just had to help my mechanic with some tech knowledge you supplied to us youtubers, the part about not enough psi. My chevy 3500 only had 20-30 psi with a new fuel pump, took it back got a new one and whalllla it started right up..

Tim is an excellent guy. I spoke with him about a failure to start that I was having and he was happy to talk. Thank you sir!By the way Tim, it turned out to be a weak spark from the dang coil!

Your a super good dude! You have helped me out on many occasions with your videos. Thanks for all you do!

Wow, great video all the way around. Thanks for posting and hope you are doing well.

Thanks Tim! Be safe and good health to you!

May God bless you and your wife and bless your business.... continued success

Some great advice on the repair as well as the virus . Stay safe Tim

Thanks for those very Patriotic humbling words Jim, awesome.....

That's a good summary, those GM pumps can be very noisy even when functioning normally. Agree completely with your remarks at the end, stay safe.

Thanks for the video. And for the thoughts at the end. Hang in there

1999 Sierra here, my no start issue was due to ignition switch not sending 12v to the pcm while in the crank position (but only when cold, never had an issue during the summer). I took it to an independent shop, who successfully diagnosed the problem. Shoutout to Denio Automotive in Phillipsburg, Ks! I had them bypass the issue, (instead of buying the correct but very expensive part) with a push button(leave the ign. sw. in the on position, then push the button to run the starter). This was after I had a dealership mechanic(on his own time at my house) replace the intake gasket, because he was "pretty sure" that's what's wrong, never did any other diagnoses. Then I replaced the crankshaft sensor, then the camshaft sensor. Hope this saves someone else some trouble.

Excellent work!

Hope you and your family stay healthy there too Tim.

Blessings Tim. I always enjoy your videos. Well it’s a year later and here we go again! Prayer during these times is very important. My youngest son is in the Middle East. Not a good time to be there. So, if you think about it, please add Bryan to your prayer list along with the nurses and first responders and all who make a living being in contact with others on a daily basis. Bless God America!

Hey Tim, I just subscribed to your channel, and just wanted to say Thank you, for all you do.

Thank you! Be safe!

Good day from Ontario. Yes it is serious out there. Thanks for videos. Be safe.

I love yall man. Stay safe. -PawPaw

This video helped so a big thanks to you

Well said! Good video also. I can hear my pump failing the way my '07 starts. It just doesn't light up the way it should. 115,000 miles. Not bad for a GM pump.

Tim, best wishes from New Zealand. Stay safe.

Thank you so much.......dude your awesome!👍👍👍🙏

Thanks again for another informative excellent video.

Great video tim as always

Love you brother great video. WE WILL SURVIVE.

The short rubber hose that connects the fuel pump to the metal feed line inside the tank prone to deteriorate and leads to low fuel pressure or no pressure at all. I found this myself when I removed the pump from my 2002 GMC 7500 HD Kodiak truck. The in tank filter was separated from the pump that worked unprotected and short lived.

Great video!!!!

Cool good video. Thanks for sharing it. I hope you are doing well and staying safe.

Having similar problem with an 02 Silverado, crank, no start, fuel pump runs, and left me stranded.. ..Fuel pump was replaced a few years ago..I'll have to get it home to test the pressure and check codes..

Pass me that wrench. Thanks for the Tips. I like listening to some one, who knows his stuff. Have a great day. G,)))

Always enjoy your videos. Thank you for sharing. Appreciate the kind thoughts and words. Stay safe yourself.

Thanks for the vid Tim, especially the shout out to the healthcare workers and mechanics as they both have to be extra careful with the pandemic. Stay safe & healthy.

Stay safe tim

You'd figure chevy would have fixed the fuel pump problem by that year. I got a 98 with a few fuel pump replacements. Hello from NC! You stay safe up there. 30 more days of stay home rules here. Praying this thing comes to an end soon. Thanks to everyone that's trying to make a difference.

I had that same exact truck pretty much and did the same thing where it would stall and not start but it would crank. Fuel pump sounded normal and it ended up being a crankshaft position sensor

hey I was wondering is there a year of the silverado between 1990 and 2004 you would say has least amount of issues and is good years for chevy ?

Thank you Tim!!!!

God bless y'all!

We prey you stay well car Dr. We also prey that Chevy had an empty gas tank to replace the fuel pump...HAHA

Subbed. When I use a tip or two of yours that’s the least I can do. Thanks

Some models have the fuel pressure regulator in the tank with the pump.

Good video thanks .

Thank u!!

Hi car doctor, great video. please correct me if I'm wrong . Wouldn't the vehicle try to start with 32 psi . I have a 2010 6.0 ls swapped range rover that has the same conditions. Rarely and randomly chooses when it doesn't want to start . Most always does start. I have been able to duplicate the problem . If I start and run the truck for twenty min , thirty mins whatever. I can immediately turn it off and restart it. And it starts , But if you leave it running and turn it off , wait twenty mins and try it wont start for two three hours. Any help is appreciated . I also have a 2000 silverado 6.0 does the same thing once every blue moon . Then hours later runs no problem

I have a '97 GMC suburban I'll replace the fuel pump spark plug, wires, rotary button, cap, and the fuel modular and it still will not start,I don't know what to do any tips? love your videos

hey man i’ve been looking at videos for this exact problem with my 03 silverado, and i’m in anchorage alaska as well, any way you could help me out?

Thank you

Mr. Car Doctor. I own a 07 GMC Sierra 1500. The voltage gauge at times shows low voltage. Truck starts fine but voltage gauge shows low charging. With day running lights on and AC on is when issues start. Any suggestions? Please and thank you.

hi, my friend stay safe out there.

I will have to look at that. Thank you.

CAN YOU DO ONE ABOUT THE TRAILBLAZER, MINES START BUT ONLY FOR A FEW SECONDS AND THEN THE CAR WITH THE LOCKING SYMBOL COMES ON, ITS DRIVING ME INSANE! I ALREADY TRIED THE 30 MIN RESET AND ITS STILL NOT WORKING

Do you recommend an AC Delco fuel pump??

Hey tim i have a 2003 gmc sierra 1500hd with 6.0 i replaced crankshaft sensor. Camshaft sensor. Fuel pump…fuel filter. Air mass flow sensor. Cleaned my grounds… replaced pcm and its still having a intermenting start… any thoughts.. only thing i didnt replace was throttle body and tps. Think that could cause a intermenting start. Its not everytime i crank. But every few cranks it will have a hard crank…

Well said Tim.....

I have 2001 GMC YUKON DANILE . The engine in good condition and i was driving it, parked it came back to start it. Didn’t even ant to start but was turning over. So i thought it was the fuel pump. Switch it out. Put all back together, now its still doing the same thing. I also took to one best in town mechanics. Got it diagnose. They couldn’t find anything wrong with it neither. They think it could be the anti- theft system that shutdown the fuel. But i still dont know if that is correct. I need of some advice.

Having the same problem but with a 2000 Silverado v6 could it be the fuel pump or fuel pump regulator

I have this 2000 1500, this one time she cranked but didn’t start so I disconnected the battery and she started after that. But now she won’t start again. She has a new fuel pump I installed few months ago. What else can it be?

Where did you find a test point on that?

My 2000 Chevy Silverado won’t start after running out of gas , after I put few gallons into tank .cranks but not firing . Any help appreciated

Sometimes can be the crankshaft position sensor cod p0335. Sometimes no show the code in the scanner.

my 2001 having the same issue. I changed the fuel pump, changed fuel injectors, and plugs. It rain great for a while, then one min its starting, run great, and the next it doesnt start. Im just trying to patch long enough for the new trucks prices to drop.

Very wellsaid.

You are a patriot.

Another good one Tim. M had a few that needed fuel pump replacements. The best way I did then was take the bed bolts out of the drivers side loosen the bolts on the passenger side enough and jack up the bed on the drivers side and brace it. It was easier and quicker than either dropping the tank or removing the bed. Stay safe my friend. We will get through this together.

I have a brand new 2021 GMC Sierra with 500 miles on it and it did this today. Eventually I got it to start. Not sure if this is happening on other newer trucks... It is the 3.0 L Duramax.

Need help can't get truck to turn on 4.3 l Chevy Silverado i cant get it to start changes rotor cap and distributor dont know what else to do can you help 3

Need help juts put a 6.0 on my 03 gmc but fuel won’t go into the injectors if y’all know whys wrong lmk

Could these symptoms be similar with a diesel? 06 Silverado hd

I got the same thing but I have throttle body codes on , any help ?

I had this issue tonight I was driving along felt a surge. I then hit the gas and Nothing then it would crank and not start $250 tow bill and now I'm praying it's just a pump

Dam fuel pump, it sounds like it's working too hard to last. Two balanced pumps in parallel is what it needs ha ha :-D Keep safe tim, stand a safe distance from customers, about a mile away should do nicely ha ha :-D Stay safe mate.

Thanks for the video.. I have 2000 Chevy blazer that cut out then died,will not start back.. Change pump about 2 years ago,had code for the fuel EVAP before it quit on me. I'm thinking it's a fuel issue..

some awesome advice and I thikns my fuel pupm is gone to the place of inoptedness?

I'll never know if it helps, but I almost always keep the tank at half a tank or more. I figured the gas helps dissipate heat. So far so good on my 06. A friend had to replace his on his 00. He used his tractor and lifted the bed off. Seemed pretty easy if you have a tractor, I suppose. Great information on the fuel pressure. It's appreciated you sharing your knowledge.

I replaced my ABS module on my 2002 Silverado 5.3L and did a hard reboot by connecting the battery cables together for half an hour as was suggested by Your Part Source. Now the vehicle cranks for a split second and dies. I keep thinking it is going to start but it won't. Do you have a suggestion? I visited Gwinny's in Anchorage once. Had a great time in Alaska. I would really appreciate your help.

stay safe there

03 silverado ,I believe it's passlock issues . I've reset it twice . My fuel pump only comes on with direct hot to battery and all relays and fuses are good

LOL you look the same as you did in your couple year old video i watched XD

I drove my 2000 chevy home shut it off went out next day all it did was tire over what could it be

What will make my GMC when you crank it reps really high

I am thank you

Hello dr. Big question here. 2002 suburban 5.3 No spark no injector pulse. No power. From de ecm to the fuel pump relay. I got a good waveform. From the cam crank sensor. I got 5 v. Reference. On tps - Map sensor. Etc. i use extra geound wire from battery to frame. Just in case. No ground. Vata system looks working ok Security light come on for 3 seconds. The. Goes off. No codes related to the no start. Condition Only evap system code Do you think the ecm. Will be. The culprit ? Thank you so much.

Good morning my name is George Garza I have a 2002 GMC Sierra with a 5.3 I replace the fuel pump and fuel filter and truck still won't I have power to the ignition coils and fuel pump will only start when you put fuel in the throttle any thoughts

I've got a 2004 Chevy Tahoe that will crank but won't start without starting fluid or gas straight into the air intake

My truck went into low power mode then limped it to oriellys and they said it was probably ignition switch but I just replaced relay for the second time and it fixed it then did it 30 minutes later then I figured I’d buy the switch and put it in now it will only crank and no start and even bought to two more relays and still doing the same thing just still cranks

I have the same problem with my 2000 chevy express g2500 but the fuel pressure is in the 50s, what else can it be?

Hello i got a question for u are anyone. I have a Honda Pilot 06. This morning i got to work. It started leaking from the radiator Reservoir. Would you have any idea what would cause that???? Any help at this time would be thankful.

My truck was running fine yesterday I started this morning and it would start and die I drove to work when I left work is started I got about 20 feet and it died and won't start back up I can hear my fuel pump I do have a week fuel pressure but I'm not getting no spark it's on a 2001 Chevy Silverado 5.3 I need some help ASAP what do you think

My 03 Tahoe just started doing this cranks but want stay cranked could it be a ground as well or the fuel pump would be the issues as I drove it fine yesterday woke up this morning wouldn't start any help 🙏

3 fuckin weeks ibe been replacin part why couldnt i have found this sooner went to start listened and sure enough loud clickin from the fuel pump hopfully this solves my problems will update when replaced!!

My Fuel pump is kind of gurgling? .. and it will start with starting fluid but won’t stay running maybe is my filter clogged?

Can a person bypass the OEM fuel pump and run a 12volt inline fuel pump that runs 80psi ? I just got a 2000 chevy 5.3l it dosnt have fuel pressure at the rail and I'm not sure if it has spark but I fund a vid on the spark issue ground wite
