My bad I thought I was talking with Billybobf getting you a dial gauge will be more difficult. There are four bolts that hold the IP pump in place, three 13 mm from the back side one through the IP pulley. The one down low is most often overlooked. Crack the IP nuts a bit and the pump should rotate easy then. Move pump towards engine, retighten IP nuts on lines and one bolt up front to secure pump. Then restart. Once running you can loosen IP bolt and move pump and secure when it gets right. Then tighten all the rest of the IP bolts but loosen all the nuts to relieve tension on them. Then retighten.
If the belt is not tracking straight, check the hidden bolt and conical nut that hides beneath the injection pump opposite the belt end. If missing or loose, can cause this.
ok, so I have to ask, is IP timing best set by ear after getting it running right?it seems to me worn parts and other issues would cause mechanical timing measurements to vary widely compared to actual injection points
