At the back of the truck where the sending unit plugs into the wiring harness there is a two wire connection to the fuel pump. When you turn the key to the on position should one wire "gray" be powered for a few seconds and the other be constant or no power, or is that wire for the fuel gauge? I am trying to determine wether my fuel pump is good or not.
have the same problem?
