The diagnostic procedure is basically universal. If you ground the fuel gauge wire, and the gauge shows Full, then the gauge is good (and the sender is the culprit).
The wire needs to be removed from the sending unit before doing this. Attach the connector to a good grounding point and turn the key to the 'run' position. The needle will sweep from its rest position to the opposite side.
