I have a 93 JGC and estimated fuel left in the tank does not work. It just says OC. Can't figure out why it doesn't work. Everything else works great. (Temp, odo, tip, etc). Any ideas? PCM, Pump? Thanks.

Nedd to go to dealer, and have them re-set the computer. Its in SAFE mode or something simmer to it. this will correct this prob. I know this can happen when it is trying to get the out side temp on the display.
