Ryan sounds like your heading in the right direction , it would really help you if the fellow with the scan tool could look at the ICP while cranking , the manual says it needs min. of 500 psi to start , does it have enine oil pressure when cranking ? Also said the oil resvior should be within 1" to the top , good luck !
It is about 6-8 inches from the top, so definitely not good.
Does the rpm reading on the tach move when you crank the engine? If not you may need a crank sensor for it to fire the injectors. From your description it sounds like the oil level in the high pressure oil pump is low, with out seeing it I can't say for sure. That will also cause the injectors not to fire.

Neighbor Brian gave my Dad a new crank sensor when he was working on it, so that is not the problem.
