If the crank shaft can't be moved at all from the front pulley, you're wasting time taking out injectors and all that stuff. Any engine that is not siezed will turn at least a little in either direction and if it has been standing there will not be enough compression in any cylinder to stop it moving. If it doesn't move, it is siezed, end of story.
Question is, is it siezed on the crank or in a cylinder? It could be either but my worry is why didn't an alarm go off? Either an overheat or low oil pressure would have caused an alarm to scream (assuming they're working).
The other thing that could have happened is a leak in the header or a sleeve due to corrosion that would cause salt water to leak into a cylinder or two. If this has happened then that/those piston/s will not be moved, forget about boiling oil and all those "fixes". Nothing deteriorates quite as fast as a cylinder sleeve subjected to salt water. I know, I have had this and in two days the engine could not be moved.
I suspect this is probably what happened and if so, then the yard is not responsible. Just my opinion but born of bitter experience.
