How cold are you getting? This sounds like a classic bad glow plug relay/dead glow plug scenario. What happens if you plug the block in for 4 or so hours during the day? Watch the RPMs while cranking if you want to see what the CPS is doing.
On the fuel... On the driver side of the full bowl there is a schrader valve. Pop the valve open and see if any air comes out. It may take a few times of cranking/purging air out to completely clear the air out of the fuel system.
Looking at your IPR data the high pressure oil system is operating normally. I really don't think it is the IPR. HPOP also looks good as it is peaking to 3000 psi. Fuel system, however... you should get a good squirt of fuel when you press the tip of the schrader valve (especially if you have just tried starting the engine). I would look closely at the fuel system.. The pumps (even new) have been known to fail sooner than the originals.
