Something I've seen is the end of the pump rod being bent out of shape. That 90 degree bend where the rod hooks into the bolt is a weak spot. Repeated pumping can cause a fatigue crack, which may prevent the bolt from coming fully forward and firing.
If the rod is cracked or bent in any way, it may be contributing to the issue at hand.
