So it all started while driving 80 down the highway. Engin started to sputter kind of like it wasnt getting enough gas. So I pulled up to a gas station thinking mayby I had some water in the gas, so I poured in some heat, let it sit a little while and tryed it again, same thing, let it run for a little while letting the stuff mix. Kept trying this for some time but to no avail, pulled it back to my place and gave up for the night. Pickup would start run fine untill it started to warm up and then it would start to run uneven and eventually just die, but it would still start right up again. Next day I changed the fuel filter, no help, then looked around for any vacume lines that could have come off, all were on. Thought maybe it could be something with the plugs/wires/ or distributor, changed the plugs, wires, distributor cap, rotor, ignition module, and ignition coil. Now the thing wont even start, it turns over, it fires, it almost starts but just doesnt quite make it all the way there. It almost sounds like there might be a wire that is not connected, I am going to go out and check that now but if any of you have any other ideas that it might be, your help would be greatly appreciated, Thanks in advance. 39
Check the rotor position,It could have jumped time.Could have a bad wire that goes to the coil.When you changed out all your parts,did you put on new,or something you had lying around the shop?
Well, it SOUNDS like a fuel pump problem but modern cars have many systems to go bad. If you don't have access to a scanner and a fuel pressure gauge, I'd recommend you call a wrecker to have it towed to a shop. You can spend a mint throwing parts at an engine that your buddies diagnose with them having nothing to lose.
Well everything seems to be conected and looks like everything is getting spark. Everything I put on was new.

[ QUOTE ] Well, it SOUNDS like a fuel pump problem [/ QUOTE ] I agree..........some thing happened to my 96 Siverado...... New fuel filter, checked the rotor.it was turning and in phrase......so I hit the tank with ABF rubber hammer....and it cranks.... I had the switch on when I hit it. It ran but only for enough to convince me that the fuel pump was DOA. Dropped the tank, WHY are they always full ?, and put a new GM pump in. Back to riding.......
Is this a Chevy Vortec motor? TBI with the plastic intake manifold? I had the same problem in my '38 and after replacing Everything you could think of,I found out it had a crack in the manifold.Never put dry gas in these motors as it damages the plastic manifolds....

Uhh, btw 39, what kinda truck is it anyway? GM? If so, ya might be happier setting the bed back enough to access the fuel pump.8 bolts and a helper gets it done. Had a similar prob with my 95 Silverado--it died dead at random times--thought it was the fuel pump. Replaced pump, problem soon returned. Ended up being the IGNITION SWITCH assy...and my cost was $130
Earl Schieb's story just re-inforces what I was saying. There's also a low oil pressure switch that can malfunction, shutting off the fuel pump. Like was said earlier. Give the bottom of the tank a good hard rap and try to start the engine.
