An engine control system in which control of an engine can be performed after there has been a momentary power disconnection of a power supply, such as the vechicle battery, from an engine control unit of an electronic circuit which executes an anti-theft function. A power supply detecting circuit detect a connecting of the power supply to the engine control unit. A further circuit determines on the basis of the vehicle speed and the RPM whether or not the vehicle is running. When a connecting of the power supply to the engine control unit is dectected, a determination is made whether or not the power supply connecting has occured after a preceding momentary power disconnection if the further circuit determines that the vehicle is running. The anit-theft function of the electronic circuit is disable when it is determined that there has been a preceding momentary power desconnection.
