A fuel supply control method for controlling the fuel supply to an internal combustion engine at deceleration, wherein the valve opening of a throttle valve of the engine is detected while the throttle valve is being closed and each time each pulse of a predetermined sampling signal is generated, a variation in the same valve opening occurring between adjacent pulses of the sampling signal is determined as a control parameter value, and the fuel supply to the engine is interrupted in dependence upon the control parameter value. The above interruption of fuel supply to the engine is carried out during either of the following intervals of time: (a) a period of time during which it is determined that the value of the control parameter obtained at the time of generation of a present pulse of the sampling signal is smaller than a predetermined negative value and at the same time it is smaller than the value of the control parameter obtained at the time of generation of the preceding pulse of the sampling signal, and (b) a period of time starting from a time it is determined for the first time that the value of the control parameter at the present pulse of the sampling signal has become larger than the value of the control parameter at the preceding pulse of the sampling signal while at the same time the former is smaller than the aforementioned predetermined negative value, until a first predetermined period of time elapses.
