won't start - oil pressure?
I'm having a miserable time with my E350. Seems to be oil related. Starting is the main issue. Once running, it rarely quits. I have changed my lpop for a Melling, and got only a slight improvement. The hpop reservoir empties itself sometimes - even with the Melling.
Another oddity it does is if you downshift for a hill i.e. revving hard in 2nd, and then you pop it into D because the road is flattening out, it quits. Has always restarted for me before I need to pull over, but get worrying with up to 10 seconds of cranking to restart.
I have manual glowplugs, mechanical oil pressure gauge, and a mechanical hpop gauge.
When 'warm' the readings with the old lpop are:
hpop: 600psi idle, 1300psi revved
lpop: 5psi idle, 45psi revved
readings with Melling lpop:
hpop: 600psi idle, 1300psi revved
lpop: 10psi idle, 80psi revved
It seems like my lpop can't keep up with my hpop.
This serial # is not supposed to have a de-aeration valve (that can fall out). And my oil filter base has its relief valve retained by a snap ring. I'm not too sure where else I can be losing oil pressure.
Any ideas?

No groove. The timing cover looked good.... and so did the old pump that came out.
