Re: Fuel pump runs after shut off- help needed!
If the oil is thicker that could affect the pressure and cause the pump to stay on longer. If you disconnect the wire to the oil switch the engine will start but shut off when you release the key, because the pump is not sensing oil pressure. Depending on the year and setup of the system there is different amounts of computer control.
