ford mondeo - Another dodgy mondeo tdci, wont start - track

I just took a 2003 Mondeo tdci, 130bhp model in p/ex. It came as a non runner (kind of) with 2 sets of injectors and 2 HP fuel pumps. the car would tow off and run fairly smooth at low revs, anything over 2500 rpm and it would cut out and need towing / bumping again. Immediate thoughts are fueling issues. I sent both pumps and all injectors to a well respected bosch and delphi diesel specialist. They found both pumps to be good, all eight injectors to be shot. They did further testing and cleaning and managed to get me a good useable set of four out of them. Ive reassembled everything and still the car wont start on the key. It cranks and tries to fire but its as if there isnt enough fuel going in. Give it a quick 1 second squirt of easy start and it will fire up, sometimes taking a few seconds to pick up to normal idle speed. It then seems fine after that, havent dared take it further than my street though. Ive watched the live data with my Ethos machine, everything looks normal though Im a little unsure about the fuel pressure when cranking. At best it hits 250 ish bar. I'm not 100% what it should be but I expected over 300?

Forgot to add, I get the usual codes of low fuel pressure / fuel pressure metering unit etc. These go away once it fires up. Ive learned with these ford tdci's to take fault codes with a pinch of salt.

Common rail diesels must reach at least 10,000kpa (100 bar) Fuel Rail Pressure or the ECM will not operate the injectors. Make sure you have no air leaks allowing fuel to drain back to the tank which will of course be a cause of low fuel pressure.

Took it for a quick drive when it fired up. For about 2 or 3 minutes it was pretty decnet, then it started cutting out at 2500 rpm, had to restart about 20 times to get the half mile home. Quick check using spill of hoses at cranking showed the following amount of leak off after a few attempts at cranking.
2ml, 9ml, 13ml, 12ml

The pople who done the injectors dont think that sounds like an amount to worry about and that I should be looking elsewhere for faults, what do you think?

Are you getting a general injection fault code? If so check the wiring loom near the pulleys for chafing.

Always comes up with usual metering unit fault and presssure in rail above/below desired levels. Just got a load of clear tubing so will get it put in place of the hard black pipes in fuel system tomorrow so I can see if theres any air / debris passing through to rule that out. Wont start at all now and I stupidly left it outside so getting back in a tight right angle entry garage on a hill will be fund!!
