What bothers me is that all the obvious answers we have been offering ought
to be obvious to the OP. When you open the steam valve to the engine, and
it doesn't turn, you turn it by hand. Is there any indication that steam is
entering the cylinder and coming out the other end? Does the cylinder get
warm? Does it drip water? It seems like it HAS to be a blockage somewhere
in the supply. Can you crack a connection and have it hiss at you?
