When you turn the ignition key, the starter motor spins the engine a few revolutions so that the combustion process can start. It takes a powerful motor to spin a cold engine. When you turn the ignition key to the "Start" position and nothing happens, if all you hear is just a click, or the starter cranks very slow then you may have a problem with the starter. Get your car back on the road, and don't worry about being left stranded by a faulty starter, by replacing yours today.
