First, confirm that the wire is attached to the sending unit, then:
With the ignition on, momentarily ground the sender terminal on the gauge. It should read full scale (hot). If not, be sure the gauge is getting voltage on the other terminal. If the gauge works with a direct ground, either the sender is bad or the wire from the sender to the gauge is open somewhere. If you have voltage at the gauge and grounding the sender terminal doesn't get a response, the gauge is toast.
