In a fuel injection control method in which the injector is activated for fuel injection dependent on the interrelation between pulses produced from a crank angle sensor and a timing sensor, all the injectors are activated by any timing pulse before the injector to be normally activated for the fuel injection is determined during start-up of an engine, so that start-up characteristics of the engine can be improved.
