Just another in a LONG list of electrical problems with this truck. The fuel gauge simply spins around and around constantly. Occasionally, it will stop spinning, point at a level for awhile, then begin spinning again. Was advised by Chevy service department to replace the fuel pump, as the fuel level sensor is attached to the fuel pump. This did not resolve anything. As this is only one of the gauges in the dash acting crazy, as well as the other electrical items in the vehicle not working or sporadically malfunctioning, I suspect it is either an issue with a control module, or the main board behind the dash. So far, the only actual issues it has caused is being stranded when we run out of gas.
