If the tank is currently full, do you ever drive the car? That could be the problem

What happens if you unplug the non-ground wire from the sender, insulate it from touching anything, and then turn the key on? If it still goes to full, that means there's a connection to ground somewhere that shouldn't be. If it doesn't, then something's bad with one of your components.

usually all it takes is to post a problem here for me to have a "Dr. House-like" epiphany about the problem.

it was a wiring issue. duh.

thanks all

So now I'm curious--what was it? It would be useful to know the cause so that others debugging wiring could follow that symptom to the cause.

I promise you, whatever it is, we've all done something dumber (if it was something you did), or overlooked something more obvious.

I spent two weeks trying to track down a wiring problem that turned out to be a tail-light bulb that was inserted wrong (by PO).

Do tell, my guess would be the brown wire was on the positive and the black wire was on the ground. I bought my super with this issue...took me about a week to trace back to the PO replaced the tank, but wired it opposite.

now it only goes up to empty and climbs as the tank empties

Yeah I found that if you get the 2 connectors on the top of the cap the wrong way around the guage registers and even beyond full.
