I have a 1989 Firebird V6 2.8L. My problem is my fuel gauge. Its on full all the time so I know its not working.. But what could cause it not to work. A Fuse? Or what? Any information will be appreciated. Thanks.

One more question, what would be the cheapest way to add horsepower and torque to it.
