I have a 2001 Monte ss. The gas gauge does show when theres gas In but it just stays at full. And right before it's empty it will jump to E. I'm Itching my head over here. also my computer says everything that could be wrong with it is wrong but it's not. I'm thinking this might be it but I'm not sure. How to reset or clear errors. So I can fix my gas gauge. Thanks

 

Have you checked the sending unit? My 2001 OPC did some thing of the same. Replaced the sending unit. Problem fixed.

 

Your talking about the fuel level sending unit? No haven't tried that but thanks I'll get one tomorrow

 

My Monte does the same thing.. Let me know what yu do or did to get that fixed.. It'd be really niceto have a working gas gauge.. thanks bro..

 

its the fuel sending unit. its easy to change out. theres a access panel in the trunk under the carpet.

 

Isn't there a shrader valve to release the fuel pressure near the fuel rail?

 

There is one, should be near the front valve cover, usually has a little black cap over it that you need to remove first.
