Got the pump pulled out and the tool locked in on the wing. Ready to start putting everything back together.

How far off was the pump timing? How much did you have to rotate the IP to get the locking tool in place? My understanding of the OM603 timing chain / injection pump timing gear relationship is that there is a pin inserted in the front engine cover (or into the block behind the cover, I don't recall which just now) that creates basically zero room for the chain to jump or move off of the IP timing gear. In other words, this pin traps the chain against the gear, so that what you think happened is not possible.
