Check your basics first spark and fuel...
If there ok and your sus on it being flooded, pull all your spark plugs out and crank the enging do blow excess fuel from cylinders... clean the ends of your plugs, then put them back in and see if it goes....

P.S. disconnect the coil and injector leads when you crank the engine with no plugs, you don't want a bit of spark catching some fuel vapour....
