Ok, tell me what happens when you go out to your car and put the key in to the start position. Do you always just get a click from the starter and nothing else? Turn the headlights on and have someone try to start the car while you watch the headlights. Do the headlights go dim when they try to start it and then go back to bright when the release the key?
