Would it be safe to say probably it is NOT a shorted wire since the gauge does work from full to 3/4 of a tank of gas and it does this consistently?
As for the microprocessor, if it controls all gauges and the microprocessor is bad, wouldn't it have some kind of affect on the other gauges also?
Is the yellow/white wire you mention located in the plug that plugs into the fuel pump and how do I measure the resistance (from where to where) and what would be a normal reading?
You mention the cluster may need rebuilt. Is the entire set of gauges (fuel, temp, and speedometer considered the cluster?
Is there a way to check the microprocessor?
How is the gauge cluster removed? What would be the cost to have this job done including parts and labor? Is this something I could do? I have many years of automotive repair experience but I'm not sure if this is something I could do.
One more thing. I went through all the readings of the self diagnostics found when the odometer button is held in and the key turned on and the button held for about 5 seconds. The reading for the FP (fuel level) was 212. Is this normal?
Thanks so much.
