Ground it with a jumper wire. Turn on the key. The gauge should go to empty. Remove the jumper & the gauge should go to full. If not there is a problem with the wires or the dash gauge.

You should use the "subject" line for your subject instead of your user name. I don't know if I have answered your question or not without a subject showing.
