Check the ohm output from the sending unit with a multi-meter. Should read about 230 ohms at low and 30 ohms at high (full). If you get a proper reading there, check the output where the wires attach to the gauge. If that passes, then it's your gauge that's bad. Had to replace mine a few months back.
