Basically any significant positive pressure is good. The HPFP has a vane feed pump that could suck a golf ball through a straw, but having a positive pressure at its input stops it cavitating and bad stuff happening.

I tested the glow plugs, and they are not working except for 1, which seems to draw 0.6 Amps. I'm getting my mechanic to change them next month during the service. I hope he doesn't have trouble as they seem to have the strength of a biro according to Robbie's write up mentioned earlier.

Friends of yours they are not. Good luck

Hello gentlemen.
Also facing the same issue. Tried to change the starter, the low fuel pressure pump, switching up nozzles as well.Is there any progress to troubleshoot this?

Have you got a scan tool so you can scope the rpm signal? Check it's getting a stable rpm value at startup. If not, it could be the crank angle sensor. I had to replace mine.
