Check engine light stays on even when key isnt present.Car was draining battery and seatbelt components were sounding like they were drawing power so I disconnected them.But engine light stays on but car throws no codes.When I turn the lights on the check light goes off.I think its along the lines of the fuel gauge because it doesnt work my car had rodents when I purchased it so imma pull the seats and see but was wondering where should I start and where can I trace wires for the fuel gauge.
