ABSTRACT:
A control system employs a microcomputer, which controls the starting operation of a spark ignition type engine provided with a fuel injection system. The control system is loaded with, at least, contact information of an ignition switch for connecting an ignition device to a power supply and a starter switch for connecting a starter motor to the power supply, and an output signal of a temperature sensor for detecting the temperature of cooling water of the engine. Where the cooling water temperature is not higher than a predetermined temperature, a fuel pump which supplies pressurized fuel to an injector of the fuel injection system is started simultaneously with the closure of the ignition switch, and this fuel pump is stopped during the operation of the starter motor.
