Otherwise I found it easier to take the top off the pump. Just make sure you note how many threads are on the idle screw and fuelling screw. There's a spring to disconnect on the throttle linkage inside too. Access is so much better after that.

Hmm, I would be cautious about both of those methods, risk for losing parts, contamination, etc. Especially on the turbo pumps (which are the ones with this access issue) it can be tricky to get the top of the pump back on, even more so if you haven't done it before and your first attempt is with the pump on the motor, not on the bench where you can see everything more easily.
If you scribe marks very carefully on the IP and its bracket, you can loosen the four mounting bolts and rotate the pump away from the motor, get the injectors replaced, and then very carefully put the pump exactly back where it was. You need precise marks for this to go well -- rather than a scribe you may be better off giving a tap at the joint with a sharp chisel or other more exact method -- but if you get it back to where it was you'll be fine. Less risky than trying to count turns on the IP setting screws, and as you noted, disassembling the injectors to get them out doesn't help you get the new ones back in, not to mention the risk of losing the small pieces that will come free when you open the injectors up.
Alternatively you can permanently solve the problem by rotating the pump further out, fixing it in that position, and retiming the position of the rear belt sprocket on the cam, but that requires the timing tools and more work.
