A system is provided for automatically shutting off a running internal combustion engine after a predetermined length of idle time has occurred, for installation into a vehicle having electronic diagnostic and control computers incorporated to the vehicle. A first switching apparatus is provided for disconnection along an ignition signal wire between the ignition system and the engine running circuits, the first switching apparatus having an open and closed modes for disabling and enabling the ignition system respectively. A second switching apparatus is provided for disconnection along an ignition signal wire between the ignition signal wire and an ignition signal input to an ECM (engine control module), the second switching apparatus having an open and closed modes for disabling and enabling the ignition system respectively. A data collection device receives data from said connected vehicle diagnostic port consisting of. battery level, engine RPM, vehicle speed, door ajar status, ambient temperature, handbrake status and brake pedal position. A computer is programmed to determine if said data from said vehicle diagnostic port set up the prerequisites to safe shutdown engine running operation, and to signal the first and second switching apparatuses to shut down the vehicle engine.
