Car is starting to act weird. The condesor fan came on even though the car was still cold. Car was off too. Fuel gauge shows amount of fuel in the car even though the car is off. Should show empty when car is off. Rev counter moves too much even when at constant speed. Car will not start now. Jumped it this morning and worked. Doesn't work again after I switched it off. Need help. Not sure what is going on. Thanks.
