Fuel gauge issues.

[Mycooking]

So my fuel gauge is stuck on full wondering if its the pump/sending unit or some other electrical gremlins. Any thoughts would be welcome. Car runs fine and my estimated to empty when compared with the miles on the trip is accurate so I can atleast keep a guesstimate of when to fuel up next.

You could try one of the stronger fuel injection/fuel system cleaners with a very high concentration of PEAs (Red Line SI-1, Gumout Regane) to see if that 'un-gums' the sending unit's float pivot before opening up the tank.

That has helped on some other cars which had fuel gauge problems in the past (4th gen Camaro, etc.).

seems electrical rather than mechanical. Try a reboot, as in disconnect the battery and pull/reconnect the ECU harnesses.

I tossed some seafoam in and also disconnected the battery... Then had to drive(gently) down to the dealership so my buddy could put the tune back on it(not stock) all seems good so far. I gotta do some driving this weekend any way so I'll update this on Sunday.

Tune doesn't go away when the battery is disconnected.

I felt better safe than sorry as I don't have my own AP yet.

Well after driving over 100 miles the last few days everything is as it should be. Fuel gauge is accurate and working. Thanks everyone for the suggestions before I dove down a rabbit hole. Sometimes it's the simplest solutions 😃.
