p32 8.1 erratic fuel gauge
My fuel gauge is inconsistent. When I first turn the ignition to ON, the gauge either snaps to 0 and floats to correct reading, or snaps to about 1/3 full and then floats to pegged at top (assuming the tank is has plenty of fuel). 3 times out of 4 it pegs. If it pegs, I can turn the ignition OFF for 10 seconds and then back ON again for another chance.
If it pegs, it seems to be reporting actual + 1/2 tank or so, so as I get low on fuel, it will decline to FULL and below.If it doesn't peg, then it seems to be accurate until I shut off the engine again.
Pegging indicates an open or high R in the sender line, but it's strange it doesn't always do it, and makes its choice at startup. And more mysterious, the "information message" in the speedometer area seems to report the correct miles-to-empty in any event, so I've started using that instead of the gas gauge. I'm guessing a bad contact on a relay somewhere. Anyone have any ideas??
(NB: I've had rats chew through engine computer wiring twice. So could be something I missed in there.)
