    Recently I had a company build me a fuel cell and then have the one sending unit thrown in. We added foam blocks and removed the fuel level swinger arm. I checked the sending unit wire connecting and they all receive battery voltage and ground is under .05

    My thought is that the fuel level sensor wire is telling the Ecm to disable to fuel pump from working since the level arm was removed. Could it be as simple as cutting that level sensor wire to trick the ecm into actuating the fuel pump.

    could some please share a diagram of the fuel sender connector wiring so I know which wires control what out of the 4. I attached a photo below of the sending unit connector that is described.
