Abstract
In a method of permitting an electronic control device 10A that is a fuel injection control device constituting a part of a fuel injection system of an engine 1 to generate a fuel injection signal depending on an engine operation state while determining fuel injection timing by an engine rotation signal, and to output the signal to an injector 5, thereby controlling fuel injection of the engine, the electronic control unit 10A continuously detects a supply voltage thereto, and recognizes starting of rotation of the engine 1 when it is detected that a predetermined fluctuation has occurred in the supply voltage at the time of starting or when it is determined that the supply voltage at the time of starting is below a predetermined reference voltage value, and starts fuel injection even before input of the engine rotation signal.
