Abstract
A fuel supply control system for an internal combustion engine has first and second step motor drivers for driving a step motor operatively coupled to a fuel supply control means such as a throttle valve. An initial step position setting memory stores an initial preset step position of the step motor, and a target step memory stores a target step position of the step motor dependent on an accelerator pedal position. A driver selector selects the first step motor driver for driving the step motor to the initial preset step position in response to a signal from a power-on detector, and selects the second step motor driver for driving the step motor to the target step position in response to a signal from an engine self-operation detector.
