2006 f350 no start, FICM good, no codes, sync+ ficm sync good, no smoke, whats next?

ill try to make this as short as possible
i work at a car dealer and got a good deal on an 06 f350 diesel non-runner.
the car now cranks, but dosent start, no white smoke comes out, rpm rises a little bit when cranking, sync and FICM sync shows as good when cranking.

there seem to be a weird smell after cranking for a couple of times

here is a list of everything done to the car so far:
1.replacement ecu (old one missing, came off a same year model car with same features)
2. replacement FICM (was also missing) tested gives 48v and no problems with scan tool
3.new Camshaft sensor (old had a broken connector and was giving a sync problem)
4. new fuel filter (both replaced)

tested:
-took out injectors and had them tested they where good
-did the key on engine off test from the diagnostic scanner, everything good
-removed ICP sensor and tried to start it same thing.
-did injector test through scanned, again no codes or problem showed up

from what i have read the only thing left is to remove the IPR and check if it has metal shaving?

what else can cause this problem? everything seems good from computer side and there was fuel in the fuel filter so i know the pump is working, i will try to check the IPR tomorow but was wondering if anything else i should check before?

any help would be greatly appreciated!!!

thanks alot for the help, i did some more diagnostic and ended up replacing the HPOP (got used one) new STC fitting and seals (one of the seals was bad) but im still getting no start with low icp pressure.

when cranking the ipr is at 84.76% the icp is anywhere between 16-25 psi (.26 V) i tried unplugging the icp that didnt work. i was suspecting a bad IPR but i read somewhere that a bad IPR would result in 0 PSI pressure (not sure if its true or not) that same post also said that a bad injector seal would result in low pressure but somewhere around 300psi.

so as of now im lost again, based on what i have read the low (16-25psi) PSI would point to a leaky stc fitting, but i just replaced that and all the seals that comes with it

could it be that the replacement pump i got is bad?!?

IPR is a commanded position, not an actual position. So you need to check it. Apply shop air to the HPO system to see if you have a leak and hopefully find it with a good ear. It may also help you determine if the IPR is bad, the HPOP is bad, a seal/o-ring is leaking or some of your previous work needs adjusting.
