Here's where it started.... I did a wire tuck to put the starter solenoid and all the wires around into the inner fender, I get done and then the pump doesn't work. Iv changed the fuel pump relay and it's getting power just can't figure out why it won't turn on

If it was working before you did the tuck seems maybe a wire is pinched or maybe coating cut making it ground out.he is a troubleshoot on the fuel pump

Thanks for this I'm going to go test the relay now! Iv heard that the relay will stick click even if it's bad, is that true? It would make sense because there's to circuits that need to open so one could be opening and still cause a click?
