Sometimes starter does not turn over the Engine, It just makes a click.

That was just crossed my mind as I thought more about it or I thought possibly the alternator

My wife found this one! The starter switch is worn out! The simple solution is to just not press the key all the way to the right. The car starts every time! I think that the plastic in the switch body is dented and the switch has too much travel. Easy does it starts it every time/ Press hard and you are going nowhere.
