Pour a bottle of Techron in it and run a tank through. You may have to do this a couple times and it will clean up the sensors and the tank will read correctly. Common problem on C5s and imagine GM uses similar sensors on the F bodies.

sounds like something is coming apart in the swing arm inside the tank...
or te contacts are severely worn... how many miles are on it???

the techron thing seems to make sense but it seems to easy, my car has 130,000 miles on it so mybe its just worn

could be time to replace it... but sit down. O'Rielly's wants $188.00 for the "unit", which includes the gauge sending unit and the pump all together... no one i have found sells just the sending unit...

my gas gauge doesn't work, i've been told its a common issue with our cars. mine will read somtimes if a hit a bump in the road hard or something but 95% of the time it just doesn't work, what causes this?

It could be worn, but at the price and hassel of replacing the sending unit giving the techron a try can't hurt. My Z was doing exactly the same thing at 65K until I started feeding it a semi regular diet of techron. You can always spend the big bucks later.
