Mike, Unless you just want to throw money at it, first check the timing of the currently installed IP. It is not hard and costs next to nothing. You have the instructions. The hardest part is removing the valve cover and I think you can even skip that if you can see the #1 cylinder valves well enough through the oil fill hole (I have a 617, not 616 so I'm not sure about this on a 616). You do need to remove the #1 injector line but that's easy. Do the "fuel welling up" test first, that doesn't require the drip tool or removing the delivery valve. You can make a drip tool from an old piece of injector pipe or buy one pretty cheap to do the more precise drip or the bubble method (just like drip but with air).
It will cost a few $$ to run an IP through a real test stand at a good Diesel shop and it will cost more to get a reman IP (which could also be faulty). The fact that two "good when removed" replacement IPs produced the same result implies that your problem is not the actual IP.
