Where are you picking up the oil pressure signal? My concern that with an altered oil filter housing, you don't have any oil going to the bearings. RE: The first motor burned down a rod bearing and locked up at idle. The only time a bearing grabs the crank is when there isn't oil flow.

Glow plug operation won't affect cranking speed.

You have a global problem, even if you lost 2 cylinders the engine should still run.
How about putting the original injection pump back and trying?
What are you using for a transmission?
