Recently when i start my car in the mourning i hear a faint whine similar to a jet engine. It only last a few seconds and it is around 50 degrees out. I am assuming it is my fuel pump. If it is the fuel pump starting to go about how long will it last before i should replace it? Also should i go with a replacement stock pump or an upgraded version??
