PROBLEM TO BE SOLVED: To prevent a sudden change in starting time by a little difference in the cooling water temperature, in a system for controlling a boosting start. SOLUTION: This starting control device performs " the boosting start " for taking preference of a fuel pressure increase by prohibiting starting time fuel injection in the whole temperature area, regardless of the detecting cooling water temperature of a cooling water temperature sensor 32, when detecting fuel pressure of a fuel pressure sensor 29 is predetermined injection allowable fuel pressure or less in starting. Afterwards, when starting the fuel injection when the detecting fuel pressure of the fuel pressure sensor 29 exceeds the injection allowable fuel pressure, a determination is made on to which of three temperature areas of the low temperature, the medium temperature and the high temperature the detecting cooling water temperature of the cooling water temperature sensor 32 corresponds, and the starting time injection timing is set to an intake stroke in a low temperature area and a high temperature area, and the starting time injection timing is set to a compression stroke in a medium temperature area.
