If I turn the key quickly when I start my car there is a very loud, high pitched screeching, grinding noise that ensues and the car does not start. If I then turn the key slowly, it starts and runs fine. It happens alot when the engine is cold if I am not careful/lucky in how I turn the key. What is…
