Ford Taurus , 2002 , Came here as a intermittent no start. But i tried 3 days and it started strong every time. They replaced the battery in the Ford Tarsus last week and cleaned the battery terminals. Oil leaks on the ford 3.0 engine seem to flood the starter with oil. Then when soaked with oil the starters act up. Also in the video i can hear the cam sensor chirping .Sounds like a belt. I do use a Foxwell BT705 battery tester to test the battery , starting and charging system. If your Ford Taurus does not want to start , Visually check all connections for corrosion , make sure all connections are tight , test battery , and look for oil all over the starter.
