An internal combustion engine fuel injection control apparatus is disclosed in which a basic fuel injection signal for light load is calculated as a function of the manifold pressure when the engine is operating with a light load, and a basic fuel injection signal for heavy load is obtained with the revolution number and the throttle valve position as the parameters when the engine is operating with a heavy load. The engine load condition (light or heavy) is decided in dependence upon the throttle valve position or the manifold pressure. The circuit employed for switch-over from a heavy load to a light load or vice versa preferably has a hysteresis characteristic.
