Have you done a volt-drop test on the engine ground connection?
Do you have a DC current clamp that will read up to 400A? It'd be interesting to see what the starter is drawing.

I haven't I'm afraid as didnt really get any time today. All I have is a multimeter, although dc current clamp is around a tenner on eBay, so happy to get one. I agree it would be worth knowing as it's really pulling some juice.
 
I litterally have the exact same problem with my MY07.
I have changed the cambelt
changed the LPFP as it was just delivering 0.4 bar new one delivering 0.7 bar
Checked diesel return volume (not too bad)
Volt under cranking drops to 9v on new battery
I got it started yesterday after fitting new pump but massive ignition knocking and stopped after 5.seconds
I have tried to disconnect the catalytic converter too rule out clogged exhaust but i cant seem to access all the nuts to get it loose.
Any updates on this problem?

Ah very interesting as I put a rag in exhaust and it didn't blow out so I was considering removing downpipe. But no, sadly not sorted yet, but please also keep me informed.

I might try to dismantle the exhaust right after the cat and see if it is any flow out of the cat because i cant access the bolts on the turbo

Ah ok a bit fidly to get to I suppose. Interested to know anyway. It's also interesting that you had 0.4 bar and it only increased a few psi to make it run. Gunna get me a more accurate low pressure gauge I think as I'm only at about 2psi at the moment.

Have you given the crank pulley a prod and poke with a pry bar?
The knock might not be diesel knock!
