Abstract
There is disclosed an anti-theft device for an internal combustion engine of a motor vehicle that has two features to prevent theft that come into operation upon activation of a single switch that can be hidden and is part of the overall ignition system in addition to the ignition switch. Activation of the single switch causes a three-way solenoid valve to divert gasoline from the fuel pump back to the fuel tank rather than to the carburetor and also causes a break in the ignition circuit between the ignition coil and the distributor.
