my gas gauge is sticking on my 2001 Aztec on 2003 Pontiac Aztek

also my temperature gauge for the outside temperature and the direction you go in the car is off. Also the miles left on the gas of tank in the car is off. And the gas gauge always say full and then gauge with go to empty and the low fuel light come on.

Asked by for the 2003 Pontiac Aztek
the gas gage issue is most likely the fuel sending unit have it tested.
