It could be a safety shut off but as long as it runs ok now I wouldn't worry over it.
Automatic fuel pump shutoff. It is indeed a safety feature designed to keep the street from getting flooded with gasoline should a fuel line break during a collision. Your fuel pump will also be shut off if the oil pressure ever drops below a pre-determined level for too long.The only thing that concerns me is that when I was hit the car randomly shut off. Is that a safety feature? If so that will make me feel a lot better since there really is no explanation why it shut off because I was hit in the back.
Ford's are more user friendly, meaning they usually won't require a dealer visit to reset, as for a decade or so there's a button in the trunk area that you could push to reset the system. Newer systems, even from Ford, generally require a dealer visit as their computer controlled.Insurance adjuster said Ford was the only one to have this feature.
Guess he was wrong!
