My fuel gauge has always been wrong on my 1995 Firebird. When the gauge comes off full, I know that I need to get gas fairly soon for street driving and immediately for track driving.

Yesterday through the use of a scan tool, I also learned that my water temperature reads way too low while also learning that GM has two water temperature senors in the car - one for the ECM and one for the fool behind the wheel. The ECM sensor seems correct and the in-dash water temperature gauge is wrong.

Should I be treating these two problems as separate or is it possible that these are related?

The fuel guage in my 96 was very non-linear. 3/4 tank indicated was really around half, half was closer to 1/4 (or less), and below that all bets were off.

The guage in my 2001 is better, but still not linear.

In my 96 CMC car, I installed an Autometer fuel level guage and it appears to move with the fuel level quite well. It uses the factory sender ... just attach the purple wire, power and a ground.

But in my '98, it too seemed to fall very rapidly after the first 5 gallons or so was burned off.

I wonder if it's some sort of internal resistance with the guage?
