(12-20-2021, 08:07 AM)50harleyrider For the record, temperature here is 29F this morning and truck would not start even with extended glow times above 30 seconds. This problem only occurs in cold. Maybe I should look elsewhere for my issue and start using the block heater which indeed MB provided on all these 606 engines. Also maybe consider some form of heated supply line like my oe B5.5 vw TDI has. Does this make sense or is my outside temperature too high to consider these things? I know it gets colder in Germany so I don't want to do these items unless I have to. My fuel is fresh and from a high volume truck stop.
Can you confirm the glow plugs are on that entire 30 seconds? (do you have them wired to an LED maybe?). Is there white smoke coming from the exhaust while you're cranking to indicate its getting fuel?
I don't think 29F is anywhere close enough to require heated fuel supplies or the block heater. Those typically help, but at 29F it should have no issue starting without them.
Check your IP rack position while cranking, make sure there isn't something going on related to low voltage at cranking adjusting the position.
I did a very similar swap to yours. I removed the inline EFI fuel pump in my truck and replaced it with a Carter p4070 inline fuel pump (~5psi). Not to say the EFI ford pump with a regulator wouldn't work, but there's a chance the efi pump meant for gas isn't liking cold diesel.
likely unrelated, but some additional questions unrelated to fuel supply
Have you confirmed your IP timing?
Do you know the status of the check valves in the delivery valves? my truck was running really retarded timing at low engine speeds due to high leak down in the valves. It would still start, but would always have a haze of smoke at idle, especially bad when not warmed up. Replacing the delivery valve checks from another pump fixed this.
