   Three concerns: (1) the engine light is on. mechanics cannot determine why. (2) the car has trouble starting. When I park indoors, the car doesn't start.

(3) when I pump gas, the fuel pump automatically shuts off even though the gas tank is not full. So I have to hold the pump in place and use the gas gauge to determine…
