Starters

The engine turning on when you stick the key in the ignition is not an act of magic. It's the result of a complex ignition system working under the hood to make it possible. One of the major components of your ignition system would be your starter, which receives electrical currents from your car's solenoid. Hearing a simple click when you turn the key or a bunch of misfiring can be indicators something is wrong with the starter and that it should be looked at.
