OEM BERU glowplugs? Any messages like "Engine Disabled" Cranking speed OK?

ngk glow plugs cranks ok i do have a air bubble in the clear fuel pipe every morning but i carnt find the air leak this is the only thing i can think of

Check that the fuel filter is sealing properly, not a ****part filter by any chance?

Check the O rings where the pipes go in and out of the filter. Well know leak area and covered in Land Rover technical bulletins.

just removed the manifold pressure switch and it is broken would this stop it from starting when cold it runs perfect when started

Could be a weak fuel delivery from fuel pump! This was a common fault on BMW cars with the 2.5 diesel engine..

Could be worht doing a current check on the in tank pump to see if it functioning.

thanks for your help i will fit a new fuel filter and check my tank pump tomorrow it is starting to effect me now getin stressed

just removed the fuel pipe from the diesel filter and turned on the ignition and the fuel only trickeled out its not pumping so i get fuel starvation at 3000 revs does the tank have to come off or is there a inspection cover in the floor

Canyon did a good write up on changing the pump without dropping the tank. Should find it with a search.
