Berlingo cutting out when driving?

[Renex182]

Hi everyone! First time using a forum so please forgive me if I do it wrong!

I've got a 2014 Berlingo, 1.6hdi DV6, I bought it with a fuel fault. The code was P0087, replaced the fuel rail sensor with a £13 one from ECP, made no difference. Then replaced with a £40 one as well as a fuel filter. Right as rain.

Drove 1500 miles and had a service, timing belt and water pump and new clutch in that time.

Now when I drive and the engine is cold, it's fine. Once it gets upto temp, when you drive it'll be fine in first gear, go to second and bring the orange triangle and engine fault on the dashboard. Carry on driving and it will cut the engine off.

First time round brings P0087 on, low fuel rail pressure.
Second time will bring P0093, actuator stuck open.

I've replaced the fuel filter, fuel rail pressure sensor (Delphi), actuator on the high pressure fuel pump (Bosch) and two injectors after having those tested.

Can anyone help me out as I've already thrown a load of money at it and I don't know where else to turn!
I know they're common for wiring going but does anyone have the ECU pinout numbers so I can check the continuity?

Revs and idles fine when warm, only plays up when driving.

Thank you in advance for any info!
