Winchester m200 pump chamber issue

I have a sears and roebuck winchester m200 12 gauge shotgun and for some reason the action is stuck open, and the feed ramp
Seems to be in the up position for the bolt to feed a shell. Any ideas why the pump wont close shut? Its stuck all the way open

May have something to do with the rail type ejector which is a weak point on that design. Hard to say without at least a couple of pics.

Heres a pic

Got a reply, fixed it. Thanks

Pull the trigger assy out and see what’s going on.it almost looks like the hammer has fell in front of the bolt
