A fuel injection control system for internal combustion engines wherein an injection reference signal synchronized with the rotation of the engine and in advance of the valve opening times of the inlet valves is produced and the signal is then delayed such that a fuel injection duration modulator for driving the fuel injection solenoid valves is actuated by said delayed signal, while said delay time is controlled by means of signals corresponding to the temperature of the engine and the engine rpm, whereby the fuel injection starting time is changed according to variations in the engine temperature thereby achieving excellent starting characteristics and the optimum rate of fuel consumption.
