Comment 1
Is the ground in the wiring harness that plugs in the fuel pump or is it separate ? Also I checked the fuses under the hood and the pump relay and they are good. I'm having a hard time finding the switch valve in the frame rail. I can't see any wiring running on the frame rail for the valve. -
