thanks Jack my sensor must be bad it does nothing when we go through the programming and outside it the gauge does not go to zero either  I think i need to read the ohms on the sensor outside then put in the tank and see if there is a change in readings it could be the gauge bad the gauge unwired does not go to zero but if i change polarity on the power wires it goes to below 3/4 full

any ideas

It should show a valid ohm sweep on the bench.
