Did you remove all the spark plugs before you tried turning the engine by hand? If not, you're feeling the engine compression. If all the spark plugs are out of the engine there's a mechanical problem that's preventing the engine from turning by hand. Possibly a crankshaft journal. Major engine repairs are needed. Hope that helps! Jim

Yep internal engine damage has happened. The last rig that I ran into that did this it had thrown a rod.
