Did you test gauge-movement, with sending unit removed from tank, and moving float, by hand, through its extreme positions? This should be done with a wire run
directly from send-unit to gauge--
not using the 'factory' wire. Also, the 'power-input-terminal' should be from 'fuel-gauge' terminal at fusebox. *Check this terminal, with switch "ON", to ensure voltage is present and getting to gauge.* The "TANK" terminal should NOT be grounded directly, but
only through the sending unit.
