A foot controlled engine start and stop system characterized by a control circuit arranged among an ignition switch, an ignition grounding circuit, a warm-up switch, a starter motor, an accelerator pedal, an alternator and an actuator to disengage the parking brake when the engine is started. The system controls automatic start and stop of the starter motor and engine by feeding back the output frequency of the alternator. When installed on an off-road utility vehicle, this system, will allow the operator to conveniently start and stop the engine by depressing or releasing the accelerator pedal. The system senses the engine speed by monitoring the frequency of the alternator output voltage and disables the starter circuit when the engine speed is at or above a level necessary to allow the engine to run without starter assistance. When the operator removes his/her foot from the accelerator pedal, the ignition circuit is grounded to stop the engine. A warm-up switch is incorporated to disable the grounding switch when the operator wishes to allow the engine to continue to run while not present.
