SOURCE: fuel gage does not work
I just fixed that problem in my 87 Toyota pick-up. My fuel gauge showed FULL all the time. The sending unit in your fuel tank has probably croaked. I had to drain the fuel tank, remove it, and try to remove the screws that hold the sending unit in. The screw heads ALL snapped off due to them being 21 years old. Ended up having to buy a new fuel tank, as we couldn't get the broken ones out of the tank. Found an aftermarket new tank for about $275 at Advance Auto. Sending unit is only avaliable from Toyota for about $125.

sounds to me that the gas tank is not grounded or 12v was supplied to sender unit wire and damaged fuel gauge
run a ground wire from battery neg (black) post to clean metal on tank
