Having problems with your 1988 Chevrolet C2500 ?
I need instructions on how to replace a fuel pump in a chevy sierre 2500 truck.
Those are pressurized pump in the fuel tank. You should have a inspection access plate on top of the fuel tank(s). If there is more than one tank be sure the relays and the system to change over tanks is working properly. First thing starting it , in the morning , turn all out side noise off, turn key to on position just short of cranking the engine over ,and you should be able to hear the pump in the tank , making a low growling noise , if it is working propery , this will last about 30 seconds while the pump builds pressure.
