@lookup , Larry, General motors fuel sending units have been bad for years, they are found in the fuel tank as part of the fuel pump assy. Then in about 2003-07 faulty gauges became a problem because of flawed gage motor(stepper motor) which control the needle on the gage. The problem could be gauge, sending unit, fuse or wiring. The most common gauge problems are either a bad ground at the tank, or a fuel sender problem. It is best to check the fuse and all wiring connections are clean, tight and free of corrosion as a first step. Some times the fuel gage/sending unit problem can be picked up by the on board computer and is called a trouble/diagnostic code, Some of the auto parts suppliers offer free code reading like Pepboys, Nappa, Advanced auto parts,etc and some of the guys are very knowledgeable and may have seen the issue often and put you on the right track.

The links below will tell how to run through some test to diagnose the problem. Good luck. I hope this helped you out, if so let me know by pressing the helpful button.
