An anti-theft system and method for automobiles cuts off the fuel supply from the gas tank by not opening a cutoff valve if a car has been improperly started. Auxiliary units associated with the ignition and the gas tank require that a certain timing sequence be gone through in starting; if the key is accidently left in the ignition for an extended period of time, the fuel will be shut off, or if the car is hot wired, the fuel will be shut off. In either case, an operator's personal code must be re-entered.
