My daughter's Sport has developed a problem I believe is related to the fuel gauge sending unit. If the fuel tank is not absolutely full, and you park on a slight incline, the fuel gauge sticks on "EMPTY" and the check engine light will come on. This is intermittent problem, the check engine light goes on and off, and the vehicle passed emissions this week. A fellow Isuzu owner told me the gauge can go bad and cause this, there was a replacement kit for the sending unit that cost about $85.00 but labor to install this is about $250.00.

If anyone knows anything about this I would appreciate hearing about it.
