I am not a mechanic, professional one that is, but from my understanding the HEUI system which was developed by cat and licensed to International...the theory of operation is the same.
You need high pressure oil to fire the injectors.
So if you have thinned out oil, an internal oil leak (bad O-rings), these conditions would create a scenario that while you are cranking you just can't build up enough oil pressure to fire the injectors.
I was watching some you tube videos on this and saw one engine that would fire up when cold, run all day just fine, but when you shut it off and went for a restart, it would not start.
In that video you could clearly see that the "COLD" start the engine cranked a long time before it started.
On this particular video it was two things causing the no start.
One was a blown o-ring on the injector and the other was the turbo vgt was stuck, would not cycle thus complicating the no start scenario.
Hope this was helpful...
