Abstract
A fuel supply control system for an internal combustion engine comprises a start detecting device for detecting a starting condition of the engine, and a starting fuel supply device for supplying an amount of fuel required for starting the engine which corresponds to an output generated from a device for detecting an engine temperature, when the start detecting device detects the starting condition of the engine. A timer is associated with the start detecting device for counting time elapsed from the time the start detecting device detects the starting condition of the engine and generating an output corresponding to the elapsed time. A fuel decreasing device is responsive to respective outputs from a throttle opening sensor and the timer, for decreasing the amount of fuel for starting the engine, supplied by the starting fuel supply device.
