Auto anti-theft system

An auto anti-carjack and anti-theft system comprising:

• an ignition circuit for an engine;
• a pulse generation circuit producing a control signal operably coupled to said ignition circuit;
• a battery connected with said ignition circuit for providing starting power and running power;
• an engine starter operably coupled to said engine;
• a starter solenoid having a relay coil and starter contacts;
• said starter solenoid relay coil connected in series with said battery and said ignition circuit;
• said battery connected in series with said starter solenoid starter contacts and said engine starter to provide said starting power;
• a first isolation gate connected in series with said starter solenoid starter contacts and said engine starter for selectively conducting said starting power to said engine starter from said battery;
• a first isolation gate trigger resistor;
• a first isolation gate trigger connected in series with said first isolation gate trigger resistor;
• said pulse generation circuit connected in series with said first isolation gate trigger resistor;
• said ignition circuit for initiating said starter power to said starter solenoid relay coil simultaneously with said pulse generation circuit sending a voltage pulse to said first isolation gate trigger resistor for triggering said first isolation gate into a state of conduction permitting passage of said starting power from said battery through closed starter solenoid starter contacts via said first isolation gate to said engine starter;
• and
• said ignition circuit adapted to terminate said starting power to said starter solenoid relay coil as said starting power is cut off to said first isolation gate by said starter solenoid starter contacts opening and said first isolation gate reverts automatically to a non-conductive state;
• said first isolation gate being retriggered into a state of conduction before said starting power energizes said engine starter.
