Presuming it is swinging (starter turning engine) and the
glow plugs are working well and diesel is clean, the other alternatives are a
drop in fuel pressure through the injectors which is necessary to ignite the
diesel, or engine compression. If the compression is too low the diesel will
not ignite. Test the injectors and
compression across al cylinders. Being a turbo the compression si already lowered and the slightest drop will have an effect. Happy hunting.
