Alright guys took me a little longer than I expected. Here's what I have after my hpop change, rpm 156 fuel PW 6 MS ICP 31 psi (way low) ipr BW 14.8% icp .22V, I dead headed the pump and I'm getting nothing on my mechanical gauge. Am I looking at a junk pump off the shelf? Bad ipr? Need some help here. Injector buzz test was good no codes, not a pcm or idm problem.
Added questions- the pump dead headed will still show low pressure with a bad ipr, correct? Shouldn't the ipr BW climb higher closing the valve to direct more pressure to the heads??? I'm going the right way here aren't I?
Yes, the IPR% should increase if everything else is good. Are you sure the PW is 6 MS? It should be 0.6 MS waiting for ICP to climb to 500 PSI or higher then go to 1-6 MS. Try unplugging the ICP and see if any of the parameters change.

here's what my computer gave me hussler, I'll try unplugging the icp here in a bit, I just woke up, gotta love working nights lol
Yes, that's .6 milliseconds, that's good. It means the PCM is detecting CPS and the PCM and IDM are in lock (talking with each other).
.006 would be 6 milliseconds.
So for some reason the PCM is waiting for HP oil to ramp up but it's not, so ... It's puzzling why the IPR% isn't even trying. If it's not the PCM is waiting for some other parameter to kick start everything.
Stupid question, but you do have the HP oil reservoir full of oil?
Update, unplugged the ipr to check voltage, it has 12.15-12.2 plugged her back in duty cycle goes up to 65% while cranking still no pressure at dead headed pump

Yes sir, res is full, I'm going to hook everything back up and crank again, I'm wondering if I have a bad test gauge. I wasn't getting any movement out of the D.C. this morning
Here's where I'm at now, everything hooked back up, removed mechanical gauge unhooked icp, now it's showing 2219-2230 psi of injector pressure. Truck still won't start. Shows 33% DC with 2200 psi
