I've actually had this problem for a while but my fuel guage stopped working after I got rear ended back in early 2005. I've just been calculating the mileage to about 220 miles before filling the tank back up. It's worked out so far but I want to correct the problem. I pulled the code and I'm getting:
P0463 Fuel level sensor circuit high input
I'm not exactly sure what I would need to replace or repair, in this case.
I do have a Walbro 255lph fuel pump, but it was working after I installed it and continued to work for a year or so. I know it had to be something with the accident but at the time my insurance co wouldn't cover it because I had modified the fuel pump. Any help would be appreciated!!
