Q: Will not start

When your car fails to start, the first observation to make is if the starter is cranking over the engine or not. This is the actual sound of the car starting. Otherwise, if you hear a slow crank or no crank, the issue narrows down. This is the sign of a dead battery or a failed starter. The battery could have died die to a light being on, or other simple matter. The battery could have also died if the alternator was not keeping it charged. If the vehicle cranks but does not start, there may be a more serious issue. At that point you will need to check the fuel, air intake, and ignition systems.
