I filled the gas tank earlier during the week and I've driven about 80 miles and the gas gauge still indicates that the tank is full. When I turn the engine on and off, the needle moves as it should. The problem is that it's not indicating the proper amount of gas remaining in the tank. What could the problem be?

sender unit in tank may be failing. have a sweep test done to check the dash unit. if that is ok, then the sender in the tank is at fault.

Pull the connector to the fuel sending unit in the tank. You have to remove an access cover to acess.

W/ ignition switch ON the fuel gauge should show empty. If it stays on full, you have a short somewhere in the wiring that's grounding the voltage supply line to ground. Trace short.

If gauge shows empty, then fuel gauge sender is faulty and must be replaced. Remove from tank and replace w/ new or used working sender.
