here's the scoop:

Remove pump after (or before) locking it with the tool at 15 ATDC on #1 (it will only lock at that position.

Verify crank/cam timing, and set to 15 ATDC by rotating ONLY in normal (clockwise from the front) direction using ONLY the crank bolt (27mm). This will get the engine at correct postition.

Make sure the pump is locked correctly -- that is, the locking bolt catches on the "button" in the pump, it's not just holding the pump by friction. I believe you can see the "button" through the lock hole with a flashlight.

Install pump and loosely tighten the hold down bolts so that you can rotate it slightly with the adjuster on the flange.

remove lock tool, rotate engine round normal direction twice and stop at 15 ATDC. Adjust IP so that tool will lock onto locking "button" using the adjuster if ncessary to get it exactly right.

Tighten pump bolts, then install vac pump, etc.

I suspect what you did was turn the crankshaft to adjust the cam timing, and this pulled the IP forward a bit.
