Chevrolet Silverado 1500: My fuel pump does not come on when

Customer Question

My fuel pump does not come on when turning the ignition key to the run position. I have swapped the fuel pump and tested fuses ENG I, ECM B, and ECM I which all turn the light on. When testing the PCM signal slot, I have 12 volts on it constantly, with key on or off. Do you have any ideas for me?
