96 Grand Marquis digital gas gauge now shows CO instead of gallons of gas left why?

Answer 1

Sometimes the fuel sensor gets to high and it causes and error. It is always a good idea to stop pumping when the pump shuts off. I can now answer my own question above. About 2 months after my digital gas gage on the above car started showing "CO" instead of how much gas was in my tank, I came out to start my car and it would not start. It had ran fine the day before so there was no warning. My starter turn the engine over but it would not fire. I pulled one spark plug with wire still attached and turned the engine over and saw a spark. I thought it must not be getting gas but I knew I had an almost full tank. I had car towed in to a garage. They told me some small animal, probably a squirel, I have a lot of them around, had chewed my wires leading to my gas pump. After they replaced the wires the car started fine. The bonus was that now my gas gauge works again. They said the wires were in the same group of wires they replaced. I dont know for sure if the animal had chew some wires 2 mths earlyier and then came back to finish my car off or what but a least the car now runs and the gas gauge works again like new.
