The symptoms tell you that the cams are not being turned at all--folks that lose a timing belt know the feeling when the belt breaks. Watch the cams while someone turns the starter--you may have sheared a key in the crankshaft sprocket so that the cams don't move, but the chains are tight. Hopefully, the engine is a 'non-interference' design so that you won't have to deal with bent valves or 'punched through' pistons. That will be a major repair if so. It might be cheaper to replace the engine with one from a wrecking yard if it is an interference design. Hope this helps!
