Full Answer

A starter motor uses electrical power to rotate the pistons and values of an internal combustion engine prior to ignition. Vehicles that have a bad starter are unable to start, and turning the key often produces only the rapid clicking sound of firing spark plugs or the high-pitched mechanical grinding or screeching noise caused by a starter that cannot engage with the engine's flywheel.
