What about the switch valve in the frame, and power and ground to each pump.

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.
