A method for starting a multicylinder internal combustion engine having electromechanically actuated inlet valves and outlet valves includes, during a starting operation, for at least one revolution of a crankshaft of the engine, operating the engine so that pistons of the cylinders, which are simultaneously at top dead center, perform in parallel an operating cycle including intake, compression, working, and expulsion, respective inlet valves of the cylinders being simultaneously opened and, after executing the intake and compression stroke, performing one operation selected from the group thereof consisting of ignition, fuel injection, and both ignition and fuel injection, simultaneously, and, after executing the working stroke, opening the outlet valves simultaneously for the expulsion.
