If there is a clicking noise when you attempt to start the engine and the engine does not crank, it typically means there is something wrong with the battery, such as a low or discharged battery or corroded or loose battery cables. If the engine cranks when you attempt to start the car, but fails to turn over, this may mean there is a problem with the fuel or ignition. Other common reasons an engine may fail to start include a failure of the starter motor relay, a clogged fuel filter, a defective fuel pump or an ignition switch failure.
