Gremlins in the gas tank

GoneYukon · February 7, 2006

If I let the fuel level get to a little less than 1/2 to 1/3 tank she won't start after sitting over night. Our driveway is very slightly inclined, maybe 5-10 degrees and I pull in, not back in so the front is a little higher than the rear. Where is the gas pickup? If I add 5 gallons when it does this it starts right up. Its kind of a pain to have to fill it at 1/2 tank all the time. Anyone else experience this?

That's odd! What happens if you back in? Just seems like with that much fuel sitting at a slight incline wouldn't make a difference.

My thoughts exactly! I haven't backed in to try it.

Not exactly your same problem, but every since I replaced my fuel pump in my '97, if my fuel level gets like yours, when I drive up my driveway the truck will sputter. If you figure out what it is, post it. It may help me figure out what's going on with mine. Thanks.

I have an 03 silverado and I know the gauge pickup is in the rear of the tank. If I park on an incline with the front higher than the back the gas gauge reads higher. That doesn't mean the fuel line pickup is in the back though. I have been almost empty and parked on an incline and not had a starting problem. You might have another problem.

you obviously have a problem with the suction, pick-up, part of the pump system. It has nothing to do with the placement of the pick-up.

Drop the tank and inspect the intake filter. I believe the problem will be obvious.

Any one want to second that? How difficult is it to drop the tank?

Real hard when full, not so hard when empty.

That doesn't help me....

Well i know those pumps are completely bathed in gas until you get below 1/4, so it really doesn't make sense that it wouldn't pick up. I'd have a look at that pump.
