PROBLEM TO BE SOLVED: To prevent an air fuel ratio from becoming overrich in restart due to fuel leaked from a fuel injection valve during engine stop. SOLUTION: A map for storing start time injection pulse width corresponding to start time water temperature and engine stop time is provided, and based on the start time injection pulse width retrieved from the map, fuel injection in start is controlled. When the start is completed, an air fuel ratio is detected by an air fuel ratio sensor. At the time of next start, the start time injection pulse width is corrected based on the detection result of the air fuel ratio, and data on the injection pulse width in the map are updated.
