Fuel Gauge Problem

CTScott,

1) On cleaning the resistive strip.
Whats you opinion on using fuel cleaner, Redline in the gas tank to possibly clean the strip.
2) I replied to another thread where the person reset the ECU. Would that re-learn the gas sender to gas bars?

Thank you for your knowledge.

I am not sure about if fuel system cleaner will help or not. I have a gut feeling that it will considering that I had a Subaru that had a fuel gauge issue, which eventually healed itself.

Resetting the ECM will not help, since the ECM doesn't see the fuel sender, just the cluster ECU does. You can try disconnecting the battery to reset it, but it actually reinitializes the fuel level every time you shut the car off.
