I cleaned my ground wires from auxialllary fuse box to the motor and to the car frame.It would seem to me if no power this fuse only something else maybe or not? everything else is working only the fuse for the pump.really has me throughed off. put gas in the throttle body and it runs for a min. but not getting it with the pump running for a straight minute. could a fuel pump still run but just not with enough pressure to open the injectors or does this fuse and relay supply something else to. pressure regulator?
