    Start with the basics.


    Do you have engine spark?
    Are you absolutely sure there is fuel in the tank?
    Is there fuel at the injector, and is it properly pressurized?

I have found in these the pins in the fuse block under the hood get weak and the relay itself will show a "heat mark" on the fuse block cover if you look at it from the inside, I have had to run new wire to pump , install a outside relay , and trigger from vcm, power to 30 pin from battery, no problems, this is a manufaturing flaw, the circuit to the pump is supposed to be shared with the oil pressure switch circuit.

Trace the power source from fuse to relay etc and make sure pump is working. if all checks out then check pump working and for preasue at engine. you may have a dammaged fuel line from the tank which would also cause the same problem

The fuel pump wires are positive: pink/black and negative=black. Pull the connector, turn the key on, and check these with a test light. Your pump power runs through the PCM.

2000 silverado wont start


one good way to check that the fuel pump is running to listen. take the gas cap of and put you ear the the fuel tank fill neck. have a freind turn the key from the off position to the on position, but do not start the crank the engine over. you should hear a huming or wizzing sound for a few short moments. if you hear that sound the pump is running and more thatn likely pumping fuel.
