A fuel injection control apparatus for an internal combustion engine capable of expediting an initial explosion and hence enhancing an engine starting performance. The apparatus includes a crank angle sensor (1) for generating a crank angle signal indicative of angular position of a crank shaft of an internal combustion engine, various types of sensors (2) for detecting operation states of the internal combustion engine, fuel injectors (3) provided on a cylinder-by-cylinder basis for injecting demanded quantities of fuel (Fs) for individual cylinders, respectively, a cylinder identifying element (4) for identifying discriminatively the individual cylinders on the basis of the crank angle signal to thereby generate a cylinder identification signal, a fuel injection control element (5) for controlling actuation of the fuel injectors (3) of the individual cylinders, respectively, on the basis of the crank angle signal, an engine operation state signal derived from the outputs of the sensors (2) and the cylinder identification signal, and a fuel injection quantity correcting element (6) for correcting time durations for which the fuel injectors (3) are driven upon every fuel injection on the basis of the crank angle signal, the engine operation state signal and the cylinder identification signal.
