2005 GMC Envoy Q&A
2005 GMC Envoy Question: The gas gauge is not working all the time what can I check for this?
more than likley its the sending unit in the gas tank but a lot of times you have to get the whole unit with fuel pump which could get expensive - goodguy
recomend you have fuel tank droped and change out fuel level sensor. It a common problem with these GM SUV. there is a recall out for this problem. - epereira
