In an electronic fuel injection system, fuel is applied to an internal combustion engine for the duration of individual control pulses developed in synchronization with the engine rotation. During cranking of the engine, additional control pulses are supplied at a frequency which is inversely related to the temperature of the engine and which is also inversely related to the supply voltage of a power source. In a preferred embodiment, the frequency of the additional control pulses is doubled when the supply voltage falls below a minimum acceptable level.
