This is a good video I think it might help me out in the morning when I try to start my car we're going to try it and see it if it'll work

Not sure but on mine the fuel pump primes for a couple seconds when you turn the key to the on (not run or start) position. I’ve experienced what you describe with old carburetor cars where the gas is slowly pushed and sucked up to the engine when cranking. You might want to try replacing or swapping your fuel pump relay and also look at the lower left hand corner (7 o’clock position) when you pull the relay out for a little hole that might be marked on your fuse diagram as PRIME. You can try jumping the 30 relay hole spot (it has constant power) with the PRIME hole to see if that causes the pump to come on. It should. If not, then the pump may be on its way out. Also, I suppose the fuel filter might be clogged. Hope that helps. Cheers.

I agree! Takes a couple minutes and it doesn’t cost any money, so it is time well spent!

How long will it run before quitting? And then how long before you can get it started again and is that just by waiting or by pulling or tapping on the relay or taking a rubber hammer to fuel tank?

@@ChanceSummer it will start up and shut off 5 mins later and wont start up keeps turning but was told it could be a senser im not sure have to wait 2 hours to start it back up.and only runs 5 mins and its out

@@ChevyCruze410 wow, that is very specific so I’m thinking likely not fuel pump or filter or even relay. Sounds like maybe computer. Have your tried disconnecting and reconnecting battery to see if that clears whatever memory it has? Also, have you tried jumping relay like in this video to see if it will run longer than 5 mins? If it won’t, I personally would rule out relays and solenoids and the pump if it is always 5 mins. Did you check for engine codes to see if some engine fuel management or misfire is being reported? Sorry I’m not much help on this as I’ve never experienced that one before. If you are desperate you can always wire a 30 amp (only needs 15 but I always double to be safe) rocker switch and wire it directly to fuel pump and battery thus by-passing all computers. Basically, turn switch fuel pump comes on, turn switch off and fuel pump dies. Common in race cars not so much in road cars because it defeats the safety feature that’s supposed to turn off fuel in the event of an accident. Good way to test things though.

I guess I had something similar in a 1996 Jeep Cherokee where it would run fine for x minutes and then always die at idle and not restart until battery was disconnected and reconnected. It was the idle Control Valve. Cheap and easy to replace.

The fuse is also on the engine compartment fuse box. The relay is before the fuse (the fuse sits between the relay and pump) so if the fuse is burnt out jumping the relay won’t do anything.

It might be labelled IGN, which is I suppose linked to the computer that tells the fuel pump to turn on or not. Of course, if all your fuses are good you can try swapping a relay from something else in the fuse box compartment to see if that makes it work. If no go, then the fuel pump could be dead. I had to replace mine.

Checked. Mine is labelled PRIME, to the left (bottom) of the relay. If that is burnt out, my pump gets no power.

Not sure but if you can find the relay you can certainly give it a try.

If you have a voltage meter, you can start by making sure there is 12+ volts on the “30” terminal. It should have constant power. The relay essential works by switching (connecting) the power from 30 to 87 when the computer tells it to. All the jumper does is force power to 87 (fuel pump side). If it works, you’ll hear fuel going to the engine (fuel rails) right away. Let me know how it goes. Other guys in the future will want to know. Cheers.

Hi, thanks for watching. Note, I’m no mechanic but my crap breaks a lot so I’ve learned a lot. Look at around the 50 second mark and pause it. Look for PCM fuses next to relay. You didn’t say what year or make your truck is. Best to Google that along with fuel pump fuse location. For example, here is a result I found for an 05 Sierra, which matches my 04 Escalade. www.justanswer.com/gm/7jbku-fuse-fuel-pump-2005-chev-2500-hd.html

@@ChanceSummer oh Sorry I Have A 2002 GMC Yukon SLT 5.3 . Stalled at the light . I’ts A Crank No Start now & I Don’t Have Any Fuel Pressure Coming out the Rails As Well . I Tried The Pin Trick Yesterday & Had No Luck . I Was Told The Fuel Pump Is Bad but I’d hate to do that job and the truck Still Not Start So im trying to rule out the Silly Stuff that could Cause The Same Symptoms As A Bad Fuel Pump.

@@findon143 Got it. I’m surprised a fuel pump would fail while running. Did it give you any symptoms like hesitation, cutting in and out or not starting sometimes before it died? Mine did. And when it was doing that I would take a big rubber mallet and hammer the bottom of the fuel tank (under passenger behind driver side) and it would work again for a bit. Haha. So you can try that. Also, if you have multi-meter you should check for constant power in the top right hole after you remove the fuel relay. It should have 12v all the time. If no power then my understanding is the computer (PCM/ECM/whatever it’s called) has cut power to it. This can be caused by loose key in ignition or loose ignition so it thinks there is no key and the anti-theft mechanism GMC used at this time was to cut power to fuel pump. Does your little key / lock icon on your dash go away after you put key in ignition and turn to ACC2 (not enough to engage starter). You can try wiggling key around or another key if you have one. Then the fuse you want to check on yours appears to be the same as mine which is right next to top left (looking down on box). Look at the link from my previous reply and it is circled in a box. But your fuse cover lid should have a map. Check all fuses that start with PCM. If no luck then maybe the pump is indeed dead. The fuel pumps are a real pain to change in these trucks because you have to drop the tank or cut a hole in your floor.
