    • Disclosed is a fuel supply control device which can properly control fuel supply at any time by recovering within a short time in the event of out of phase in the drive of the step motor. In a fuel supply mechanism of an internal-combustion engine having a fuel supply control means for controlling the quantity of intake air or fuel supplied into the engine, a step motor for driving the fuel supply control means, and a control value output means for outputting control values to the step motor, the fuel supply control device comprises a position sensor for detecting the control position of the fuel supply control means, a out of phase detecting means for detecting the out of phase of the step motor from the control values supplied from the control value output means and the control position detected by the position sensor, a out of phase step value computing means for converting, into the number of steps of the step motor, a deviation between the control value and control positions at the time of detection of the out of phase condition of the step motor by the out of phase detecting means, and a control value correcting means for correcting the control values of the step motor by using the number of steps determined by the out of phase step value computing means.
