An engine starting system for a four-cylinder internal combustion engine includes an electric fuel pump connected to fuel injection valves mounted within each cylinder of the engine, an electric blower for blowing air into the cylinders to increase the air pressure above atmospheric levels within a cylinder housing a piston in the intake stroke mode, glow plugs mounted within each cylinder to ignite the fuel fed through the injection valves, and an intake valve which is normally open when a piston is in its intake stroke mode. The intake valve is constructed to close when a predetermined high pressure is within a cylinder to trap explosive pressure of the ignited fuel within the cylinder to drive the piston when it is in its intake stroke mode such that the engine is started solely by explosive power within said cylinders.
