My fuel gage stays at full all the time and the overhead gage is also not working right also now I cant even put the amount of gas in tank as the readout says I have used so now I really don't know how much gas I actually have in tank
Could be the sending unit in the tank, or the gauge on the dash. A mechanic would check the signal from the sending unit at the tank.

sokol520--Sounds like fuel pump/fuel guage sending unit. They are integrated and located inside the fuel tank, most likely.
SOURCE: fuel gauge
khooper, in another forum, told me that "Chevron Techron Fuel System Treatment Plus can remove harmful sulfur deposits from the sending unit and a filmer agent that can prevent the deposition of said sulfur"
My 05 Trailblazer LT 2WD.
Erratic readings, and when the fuel level was below 1/2 full, the needle would sit on "Empty" with the amber light staying on.
So I went to a dealer, they replaced the fuel level sensor (p/n 19177712 SEN KIT 3.107 $118.62) with labor $270.00 for a total of $398.86 this appears to have fixed it for now.
I also talked to another mechanic who blames ethanol for these deposits !

Sounds like the sending unit in the main tank is faulty.
SOURCE: fuel gage is always full even when the tank is
replace the sending unit in the fuel tank if the wires are not cut off
