In a fuel supply amount control system, during a period of engine startup from the time when a crankshaft starts to rotate by a starter motor to the time when the crankshaft stably rotates by fuel combustion, a fuel supply amount is controlled independently before and after a cylinder stroke determination. This enables determination of the fuel supply amount independently before and after the cylinder stroke determination. Accordingly, the required fuel amounts are provided respectively before and after the cylinder stroke determination. As a result, even if the required fuel amounts are different before and after the cylinder stroke determination, engine startup can be achieved in a short time.
