    An anti theft system can prevent spark, a defective engine sensor such as a camshaft position sensor or crankshaft position sensor can contribute to lack of ignition spark. Wiring harness issues, fuses, bad electrical connections, relays or Electronic Control Unit problems can all effect spark.
