This patent describes a fuel injection timing control apparatus for controlling the injection advance angle of fuel injected from a fuel injection pump to an associated internal combustion engine. The fuel injection pump including a solenoid valve which is located between a high pressure chamber and a lower pressure portion of the fuel injection pump and is opened/closed in response to a driving pulse signal so that an injection advance and an injection quantity of fuel from the fuel injection pump can be controlled, the apparatus comprising: It consists of means for outputting a first data relating to an angular position of a driving shaft of the fuel injection pump which represents a target advance angle of fuel injection determined according to the operating condition of the internal combustion engine; means for detecting the actual values of a timing which influences the beginning of the combustion of fuel in the internal combustion engine; and a speed detector responsive to the rotation pulse signal for producing speed data relating to the speed of the internal combustion engine.
