Picture was sent to me by my mechanic...dont know if it seized, also dont know about the springs. Pump mount under the hydro head (on the 1st injector's side) was loose, had even one bolt missing completly. We guess that was the reason that it blew up...such a shame...i believe that pump itself was in pretty good nick actually..
i hope that debris didnt get to injectors to clog them
Doubtful any debris made it out of the pump to the injectors. When the plunger breaks there's nothing to push fuel out to them any longer.
Guess you're looking for a new pump!

Wow, I wouldn't have thought running out of fuel could cause this.
I don't think the mounting bolt being loose had anything to do with it.
I do recommend blue lock-tite on the bolts holding the bracket to the block,... I've seen those go missing a few times,... without this result.
Thanks for posting this and the pics of what happened.

I don't think he was out of fuel, or even low enough to make a difference.
I think his out bolt got plugged, or something in the IP failed (like one of the springs).
Would be nice to know if the collar is seized, or the shaft is seized in the head, or both/neither.
Possibly springs, as i think that pump was incorrectly timed (engine shaking much more than others ive seen, and noisier) and having heavyer cold starts.
The plunger seized in a pump head and broke...
That is pretty amazing. Please let us know if you find any other issues inside the pump if you tearing it down; wonder if some metal fragments get swept into the plunger from some other part of the pump?
Mech changed the head of the pump with the plunger, and cleaned it. Works like wonder now!
