An antitheft ignition system and solenoid apparatus for use therewith in a motor vehicle having a starter motor energized therethrough by means of an ignition switch within the driver\s compartment, the solenoid having a metal cannister housing with coils therein and an electronic circuit therein coded for operation in response to receipt of a predetermined series of pulses from the ignition switch for energizing the coils of the solenoid for enabling the starting of the motor of the vehicle. A circuit is provided within the solenoid for detecting the alternating current component of the battery voltage to sense an engine running condition.
