Unfortunately......you have a gas sending unit that has failed....and yes it is located in the fuel tank...these GMs have had a very notorious tsb for the fuel tank pump and unit assembly failing due to design.....theres nothing you can do to repair this ....but you can replace this unit.....it's kind of a bear with a full tank of gas if you're gonna be doing this yourself....on the ground...this fuel tank pump unit is found quicker and more reliably at the dealership. ...HOPE I HELPED!!!!!
It's possible the sending unit just went, and it is inside the gas tank.
