On my 03 there are four wires in the electrical plug that's connected to the tank. The outside wires power the pump and the two center wires go to the fuel sensor board. High voltage usually translate to a open. This could be a broken wire, corroded electrical plug or a bad sensor board.

I took the instrument cluster out today and it tripped three other codes but they went away now so I'll see what happens
