Worn poppets? Inj questions

Truck - 2001 f350 138k - stock
Ok, so I'm dealing with a cold start issue and so far I've replaced:
- gpr
- all 8 glow plugs
- starter
- alternator
- 5w-40 syn rotella with filter
- fuel filter
- EOT sensor
- ICP
- both batteries

Next weekend I'm installing a quad gauge set up - aeroforce scan gauge (I can monitor inj pulse width, duty cycle, etc.) pyro, trans temp, boost. So when I'm doing this ill have more answers from the scan gauge. Will also change CPS next weekend

But my problem is unless I have my heater block plugged in my truck won't start(when the truck sits for more than 6 hours) or cranks and cranks and possibly starts.

From all my reading this is most likely injector problems. And most likely worn poppets. I think this is correct because the symptoms align up. The colder and thicker the oil is = poppets don't function correctly.

HERES MY QUESTION OR AREA OF NEEDED HELP - TWO PARTS

Part one
I've read that if you pull the valve covers off you can look for an oil squirt from the injector? To verify the poppet is working .... Or something along this process - can someone elaborate this and explain it correctly to me. Also to achieve the oil squirt am I simply turning the engine on and turning it over, etc?

Part two
Once I get my aeroforce interceptor scan gauge installed what are the desired amounts I want to see for duty cycle, pulse width, ..... And can someone explain what the duty cycle is looking at

Actually a third question - I'm also pricing out a new set of stock inj - most likely reman because of money but I've read that using an AD injector in #8 won't make a difference - from my understanding inj 1-7 are AD and #8 is AE the longer injector - but other members have said it won't make a difference and also that aftermarket inj are all the same size (not a longer lead one for #8) ..... Can anyone verify or give input

Thanks - I'm looking to become a DIY on my powerstroke so any knowledge is helpful

I can try and help alittle. Ipr duty cycle should be 10-12% at an idle. it will probably jump when cranking themotor over to start, but one idling 10-12 is what you want. My bad ipr was idling at 29%. I don't know alot about the injectors but i know there are poppetts in the hpop lines at the hpop. Maybe that's what they were taking about. hope that helps alittle. I don't know what the pulse width is supposed to be.

No problem:-), Another thing to keep in mind. Ipr duty cycle and icp pressure should correlate to each other, but your pcm will go into a factory preset mode and they may not correlate. My icp pressure was reading 725 psi through the pcm with an ipr duty cycle of 29% at an idle, so i stuck a manual gauge on my hpop and is was actually about 2000 psi....
