Air – vacuum in fuel supply - dunno?
Blocked fuel supply – filters - new filters applied
Faulty diesel injectors - Engine runs perfectly well when started with good mileage

Using the hand primer pump 1st thing in the morning is it already hard or does it need several presses to prime the LP side ? can't find any hand pump

Since it seems to narrow down to bad pressure when cold I'll try the pressure relief valve and the camshaft sensor (since I could buy them cheap)

but I really would need a common rail pressure diagnosis but all the mechanic shops who do this kind of test are frikkin expensive >.<

The list was by ranked order LP should always be 1st eliminated because its cost free 'eyes on', I've never known a diesel other than those with an electrical lift pump in the tank that don't have a hand-primer about central in front of the RAD and always where you can get your hand to it for obvious reasons.

Ah, just noticed from your tag line you are 2.5 not 2.8. Those EUROvans came with both electrical and not electrical lift pumps - I assume you are electrical hence the missing hand-primer.
