Re: Bad gas guage
test the gauge thus..Disconnect the sender wire from the gauge, and with the ignition on it should read empty. Hook a jumper from the sender terminal on the gauge to ground, and it should read full with the ignition on. If this does happen, then ohm the sender wire from the gauge end to the sender end, after you disconnect it from the sender. You should get lots of continuity. if you have lots of continuity, and the gauges tests out okay, that leaves the sender in the tank. Girst, be SURE the tank and sender have a good ground with a jumper wire, and see if the gauge works then. If not, you get to pull the sender, and replace it. You can use a universal sender from NAPA, you may have to buy a gauge with it to be accurate.
