This question might or might not be a problem for me, but here goes: how does one get the relationship between injection pump state and engine state approximately correct, so that when you go to do the final injection pump timing via the drip method the correct rotational position is within the range of adjustment of pump angle? Does an injection pump rebuilder typically deliver you a pump with the shaft set at some defined angle, and then you rotate your engine to the corresponding point (say, cylinder 1 TDC compression) before installing?

This might not be an issue for me... I have two pumps in play. I dropped a low miles Pick'n'Pull pump off at the rebuilder for an opinion; so far I have not heard back from them. Depending on project timing I might end up just transferring the injection pump from my old engine straight over. In that case I think that I can just set the old engine angle to TDC before removing, then transfer over to the new engine (which came at cylinder 1 TDC compression). But it got me wondering about the general case. Is it just trial and error via the drip method: try and time it, find out you can't get it, pull the IP, rotate the cuff, install again, rinse, repeat?

Thanks for your education on this...
