A gas gauge that always reads full, or beyond full, is a bad power (+) wire for the gauge. Check the wiring at the gas tank sending unit. If that checks out it's the sending unit in the gas tank. HTH -Jim

How many miles has the car been driven? If the tank was over-filled, it might take 40 miles for the needle to register. If not overfilled, the fuel sending unit might be stuck. Its part of the fuel pump which is located inside the fuel tank. If you are unfamiliar with operation of a fuel sending unit, you should take it to a qualified mechanic for diagnosis/repair.
