A method for controlling an internal combustion engine at the start of same, by means of a control system for controlling the operation of the engine, which includes a central processing unit normally operable with an operating voltage higher than a predetermined voltage. The central processing unit is adapted to be reset when the operating voltage rises across the above predetermined voltage after closing of the ignition switch of the engine. A plurality of different control manners are selectively applied for control of the operation of the engine, depending upon the position of the starter switch for actuating the starter of the engine, assumed during initialization of the central processing unit. The internal combustion engine includes a multi-cylinder engine, and the engine operation control system includes a fuel injection control system. Preferably, if the starter switch is in an open position during initialization of the central processing unit, a first control manner is selected wherein fuel injections are effected into all the engine cylinders at the same time in synchronism with generation of a first output pulse from a top-dead-center sensor after completion of the initialization of the central processing unit, and if the starter switch is in a closed position during the initialization, a second control manner is selected wherein fuel injections are effected into all the engine cylinders at the same time in synchronism with generation of a first output pulse from a cylinder-discriminating sensor after completion of the initialization. Following the fuel injection according to the first or second control manner selected, fuel injections are effected into the engine cylinders in a successive manner in synchronism with generation of output pulses from the top-dead-center sensor.
