Confirm that the engine immobilizer system (security system) is not activated thus preventing the car from starting. If the immobilizer system is on, you may see a security warning light. To temporarily override the immobilizer system, see these instructions. Short circuits and/or reverse polarity, at the battery, in a 12 volt electrical system on a car can cause a variety of effects including damaging the alternator, diodes and the numerous microprocessors on a vehicle such as those in the powertrain control module (PCM). If the starting circuit is functioning, check the fuses, fusible links, circuit breakers, and all of the individual electronic components themselves in the ignition, fuel and other circuits that could have failed due to a short circuit or reverse polarity.
