I'm sorry to hear that. The fuel pump is in the fuel tank. Make certain that all the rest of the fuel system working before you have to drop the tank. 1.Fuel pump relay or any fuses.2.Replace fuel filter,(inline between tank ane pressure regulator). 3.Trace power and ground wires from tank back to relay looking for breaks or pinches. 4.Look for a pump reset switch. If all that is good, then replace the pump. Good luck.
Make sure the all wires on the steering colum is pluged in tight. You probably don't want to here this but don't settle for anything less than a GM fuel pump. I had to replace one five times in one truck in 6months. If not the fuel pump check fuel regulator. Now on another note if this is the same truck losing power keep in mind the ECM is what pulsates the injectors for fuel to the engine. It could be back to the ground problem
You have fuel runback.Replace the injector leak off pipes then try.If this does not work then have a non return valve fitted to your fuel supply pipe close as possible to the punp.Hope that was helpfull good luck.
If you are getting spark then it may be a fuel pump problem or fuel pump relay or inline fuse. Always start Fuel system troubleshooting by replacing the fuel filter or filters! You may be able to apply 12 volts from the battery (use a fused line) directly to the 12 volt side of the fuel pump and listen to see if the pump runs. Also may need to check that it is getting a good ground to the fuel pump. Then if the fuel pump does not run independently, replace the fuel pump. The fuel pump relay is computer controlled and several other things give the computer inputs which then controls the voltage to the fuel pump relay.
On the drivers side frame rail (inside) is your fuel filter. Cheap to replace. But if you don't hear the pump cycling prior to attempting start it is more than likely pump in the tank. Check fuses first though. Big job
