Fuel System Problem
A Corvette buddy of mine has this problem:
1. DIC says Service Fuel System
2. Check Engine light
3. Fuel Gage goes to E
4. Without warning it may start working again intermittently
5. The problem continues to occur
(He had the dealership drop the tanks and put in a new fuel pump because the plastic nipple for the tank broke and leaked fumes into the garage)
After new fuel pump and the first problem they put some GM fuel additive product that supposedly removed the "varnish" but the problem persists.
This 08 C-6 A6 with 43,000 miles

If its throwing a P2068 code its the fuel sensor on the passenger side tank that is bad...they should have just replaced that when they put in a new fuel pump because now they get to go back and do it all over again.......they should have known to do that....the sensors are crap.....all the cleaner in the world won't cure it.........thanks GM!

Took my 36K 2010 GS into the local Chevy garage today to get the sensors replaced......I had contacted GM thru a service rep found on another forum back when the problem first started, when the car had 25K and was just out of the 3 year warranty.......5/100K does not cover fuel systems.....imagine that.....
Anyway....GM is covering the whole thing except for a $100 deductable......so I have to give GM some credit, they did what they should have done.....thanks GM.....
