If you could give a more detailed explanation of what is happening when you turn the key to start your car.

2) You hear a "click", but nothing else?
3) You hear the starter turning, but the engine doesn't turn?
4) The starter turns the engine, but the engine won't start up?
5) The engine turns over, but very slowly.
