if there is water in the motor he had to have done it while it was running unless the water flooded up in ur car, let me guess u have a CAI or u hit some big ass puddles. chances are u already bent a rod, once they are bent it wont start up. sohcsicivic or something along those lines hydrolocked his motor too, same complaints as u have. its time for a new motor my friend. pull the head off and see how it looks though.
