A method for advanced crank spark with blend spark retard for an internal combustion engine includes the steps of selecting whether a spark in an engine cylinder will be fired on a predetermined first or second crank edge during an engine start mode, firing the spark on the second crank edge during the engine start mode if the second crank edge is selected, firing the spark on the first crank edge if the first crank edge is selected, determining whether the internal combustion engine is in the engine start mode based on engine speed, continuing to select whether to fire the spark on the predetermined first crank edge or the predetermined second crank edge if the internal combustion engine is in the engine start mode based on engine speed less than the predetermined speed, and retarding the spark from a first spark level to a hold start level at a predetermined rate, holding the spark at the hold spark level for a hold period, and advancing the spark to the first spark level at the predetermined rate, if the internal combustion engine is in the engine start mode based on engine speed greater than the predetermined speed.
