ABSTRACT:
In fuel injection system of an internal combustion engine of a vehicle, a fuel injection valve is activated to inject pre-start fuel in response to turn-on of a main switch by a vehicle driver. A starter motor is not activated until a predetermined delay period (T.sub.D) elapses after the turn-on of the main switch. During the delay period (T.sub.D) the injected fuel is vaporized. After the delay period (T.sub.D) the vaporized fuel is taken into engine cylinders when the engine is cranked by the starter motor so that fuel is ignited in the engine easily.
