| Gasoline Fuel System problems |
Faulty gas gauge on a 1997 GMC Envoy which first lead to inaccurate and random fuel level readings. Now it doesn't work at all, prompting the check engine light to be on constantly which means the check engine light is ignored since it is constantly on - this may mask other check engine situations from being noticed.
