I have 2001 Saturn L300 (ever heard of those?). My problem is that the fuel gauge is pegged at full the moment I turn the key on and stays that way until I shut it off regardless of how much fuel is in the tank.. something about constant low or high resistance. I had fuel sending unit replaced at a saturn dealer but the problem remains. Saturn service rep was rude and insulting when I asked why that wasnt fixed. He said that I just wanted fuel sending unit replaced... that I didnt ask for diagnosis. So much for good customer service of Saturn.

I will still get it diagnosed but just want to know if anyone came across similar issue. It is a major nuisance since I constantly have to monitor the trip odometer to determine if I need gas. A sudden drop in mileage (if it happens) can cause me stranded with no gas while the fuel gauge reading full
