Hi, and welcome,

connect a code reader / scanner ,
it's the fuel rail pressures you really need with a "common rail diesel"

any history of the vehicle,
gradual adding to issues.. , any recent work done.., etc,

hi had a pressure reg and sensor fitted just not firing tryed easy start still no joy could it be the glow nplug relay??........................

you need a proper reading of the pressures, or it'll not run..

pump failure is a possibility..

Why change those two parts?
What diagnosis has been done?

Or were you just guessing?

As Charlie says, needs proper diagnostic, otherwise we are all guessing.

Is the stop solenoid not disengaging? Are there any warning lights on?
