Question about Cars & Trucks
I would do a fuel pressure test at the rail and see that you have enough fuel before doing anything else. My guess is you have a bad fuel pump in fuel tank

The problem could well be dirty injectors, try taking them out and leaving them in a container of gasoline for a couple of days then banging them out. Can it idle pretty much forever? Does it only die when applying throttle? It may be the fuel pump not delivering enough as well. Test those (the pump and injectors) and let us know how you get on.

probably not fuel filter . probably going to have to remove the upper intake and replace the fuel injector spider(fuel inj assebly) if it is droping fuel pressure it is leaking into the upper manifold

If this engine is a VORTEC then you may have a problem with the internal fuel system. Under the top plenum there is a fuel reg and poppet valves that inject fuel into the cylinders. Sometimes the tubes that run fuel from the reg to the valves can leak and cause your problem. This cannot be found with pressure check because this occurrs after the reg. PS fuel mileage will go down. Let me know if this helps.Moe

Before spending several hundres on a fuel pump, I recommend doing a fuel pressure test. You can get a test gauge pretty cheap at a parts store. If the pump is junk, you raise the truck, lower the fuel tank, unplug the electronics from the pump at the top of the tank, then with a hammer and flat head scrwedrive, gently tap the lock ring in a counter clockwise direction until it pops off. Pull the pump assembly out and install the new one. Reverse directions to install.

you have a fuel pump relay that may be defective, or fuel pump or maybe the crank position sensor,a cam position sensor.the best thing is to have a scan performed with an obd1 scanner and you will know where to start the repair.
