Gas Level never full

scflaw · 10-11-2012, 04:45 AM

Do you guys have the same problem as i do? I fill up my car to the brim and my car still says i have 3/4's of a tank... I wonder if its stuck

Never had or heard of this issue. I have experience the pump stopping before the car is full. I just kept pumping it until I think it's full. I'll keep an eye out just incase this is a new issue.

Sounds like the level sender float is stuck on one side or another. There may be a code in the instrument cluster for level sensor implausible on the right or left side, would be a good place to start. Otherwise it is just an annoyance.

yea, its just an annoyance.

That happened to me a while back. I re-set the gauges and it solved the problem.

=O how do i restart the gauges?

Do you have a JB4? That's how I was able to do it.

scflaw · 10-11-2012, 08:08 PM

Could also try putting a good fuel system cleaner in your gas tank.

Read car thru cobb and see if any shadow codes exist.
If sensor is failing it will show. There are 2 if not 3 sensors related to fuel level that could be failing. 2 in-tank and one in cluster I believe.
