What makes a fuel pump have a low voltage?
What makes a fuel pump have a low voltage? The only items in this circuit are the fuse, the relay, the inertia switch, and the pump. Low voltage to the pump can only be from a low voltage at the source or a resistance in the circuit (“dropping” voltage). What should the voltage be at the fuel pump relay? You should have 12 volts at the dark green/yellow wire at the fuel pump relay. The inertial fuel shutoff switch is between the relay and the fuel pump. The pink/black wire from the inertial switch to the fuel pump should have...
