the speedometer is controlled by the VSS (vehicle speed sensor) there must be a circuit fault somewhere ? disconnect fuel tank sender unit elec connector .. turn on ignition(not start vehicle) if gauge indicates full .. replace sender unit ... if guage indicates empty .. there is a fault at the instrument cluster .. either faulty gauge or gauge grounded in some way ..
