    Yes battery is fine. After changing fuel pump it works fine for a week or two then it just dies. This is a 5.7 EFI truck. I checked the fuse and it is fine.

If you run tank very low often, it can shorten pump life (don't know if you do) If voltage to pump is correct and system is not overcharging or spiking, check the ground for the pump...If it's not very good it will cause the pump motor to overheat from resistance. (Make a separate direct ground if unsure of condition.) I'm sure you wiped down the inside of the tank and it's very clean inside and you changed the filter when you did the pump???

This is another thing you may want to check. Make sure you have power to the fuel pump and or your fuel lines maybe clogged. Hope this will help.

A relative of mine has a '97 GMC 1500. 2 years ago I spent several weeks chasing gremlins on it. Replaced everything - plugs, wires, ICM, TPS, and some other items. How many miles on your truck? It should fire within 1 to 3 turns of starter engagement. I have to ask, how do you know there is no spark or fuel when the engine does not start? Have you checked fuel pressure? Our trouble ended up being the fuel pump. We pulled the bed off the truck and found that the lines and wires at the top of the tank were severely rusting and eroding. I would have never guessed this kind of degradation due to the fact that the truck is so well taken care of. Check your fuel pump and tank thoroughly. Also check the tank filler neck and vent. If it runs for 15 minutes then quits, sounds like the fuel pump might be cutting out. Will not hurt to check and may save you time under the hood. I have poured over those electrical diagrams for the GMC. Alot of things tied into keeping those engines going nowadays. Let me know how things work out. GC.

2000 oldsmobile bravada, won't start. I replaced


This sounds familiar to me. I assume you replaced the fuel filter, if not, do so. Anyway, the same thing happened to be and I made it to the garage somehow and they said it was the pump, located inside the tank. 3 days later I picked it up and paid $350.00. It happened again a month later and I had it towed home ( the service garage changed hands and would not honor warranty). I unbolted and unstrapped the gas tank with a jack under it. The gauge said 1/4 tank so I figured on 40 lbs of fuel plus the tank.....wrong.... The tank was empty and the fuel pump had never been replaced. I has just never run my tank down that low before, so I had no way of knowing the gauge/float was miscalibrated. You never know....

1995 nissan pickup truck fuel problem


Fuel injected or carb? Make sure fuel line itself is clear. Some pumps are designed to self regulate (carb systems) some continually pump and a psi regulator sends back the excess fuel back to the tank (fuel inj systems) If the line is obstructed then pump can't deliver fuel fulltime.

If you think pump is not on consistent, try running a dedicated wire through a switch directly to the pump. If it works then you are looking for an electrical fault going to pump. Good luck.

1995 Chevy 1/2 ton v6 starts then dies


The fuel pump inside the fuel tank might have a bad armeture or brush failure. Have someone crank the engine with the key inside the vehicle while holding foot on brake pedal and e-brake on.
Take a large hammer and bang on the bottom of the fuel tank while the engine is cranking. This should wake up the pump. This is only a temp. fix if the truck starts. That was a sign that the pump has failed and should be replaced.
Good Luck.

Replace the fuel pump relay. And if your truck has dual tanks there's three fuel pumps, one in each tank and another secondary fuel pump.

the gas gauge contacts get corroded by the chemicals in your gasoline over time, the only way to fix that is to replace the fuel sender unit...unfortunately the sender unit is usually incorporated into the fuel pump. fuel delivery problems like you describe could be clogged or dirty fuel injectors...if it's dying out on you as you drive it probably is indeed the fuel pump...usually an expensive fix. try an auto wrecker to find one for about 100 bucks.

Truck will idle about 15 seconds and dies or bogs down


You need to take a pressure and volume measurement, most fuel pressures for a carburetor engine are 3 to 7 psi, then you need to make sure the volume is consistent for a period of time, 20 to 30 second of engine cranking while the fuel is transferred to a container of some sort, make sure the ignition system is disabled to prevent you from blowing up the property.

I would check the fuel lines themselves and make sure there is no blockage. If not you might want to check your fuel injectors and see if they need to be replaced. also make sure you didnt install fuel filter backwards.
