Pretty certain it should read empty in the OFF position. Easy way to test the sending unit is to unplug it, its near the fuel tank. Once unplugged, turn ignition on. If the gauge stays on full then the fuel gauge sending unit needs replaced. If the gauge goes to EMPTY then check the circuitry on the back of the instrument cluster as well as the pink wire from the sending unit. If circuitry and wire is OK then this also points out a faulty fuel gauge sending unit.
