I own a shop, and work on many vehicles every week. I would suspect there is a problem inside the gas tank. Does the gauge read full all the time, or just when you turn it on, and then it goes to the correct measure? You could have a bad gauge causing the problem. The float assembly inside the tank works to ground. The more ground it sees, the more fuel the gauge should show. GM vehicles will show something else until the switch is turned on, and the only time they show the correct reading is when the vehicle is sitting still, or is at a steady speed going down the road. They tend to go towards full when you slow down, and go towards empty when you are taking off. In other words they move around a lot. Since the gauge works off ground, and if it shows full all the time, either there is a short to ground, the tank sensor is bent out of correct position, or the gauge must be faulty.
Glad to help out, Good luck!!!

If it stays on full reguardless of the ammount of fuel in the tank you may have a short in the wire coming from the sending unit. This may have happened from the wire rubbing something or the plug on the gas tank has come loose and has grounded itself. If that isn't it than the float/sending unit in the gas tank may be broken.

If your gauge reads full when you turn on the key it indicates a wiring problem so i would get a tester and test your ignition and other related components
