TD4 Hard To Start When Cold

Hello all, I have just recently bought a 2006 TD4 Freelander Mk1, It struggles to start when cold but once it does eventually fire up it runs a bit lumpy for a few seconds then evens out and runs fine, Apart from an initial blast of smoke that slowly goes away but never completely, Always seems a bit smokey compared to other diesels i have, Also it seems a bit sluggish at climbing RPM when i give it full throttle at idle, After its warmed up when i stop then start it fires right up with no hesitation, There is no check engine light and no fault codes saved in the ECU. I have tried a new set of Delphi Glow Plugs and also replaced the seals on the high pressure fuel sensor and also tried cleaning the EGR and it was really messy but still i have the same problem, Don't wanna keep guessing and throwing parts at it but with no fault code I've no real specific thing to look at...... When i turn key on with engine off i hear a pump going in the rear of the vehicle for over a minute or so..... Should it run that long? Starting to think maybe it's not getting the right fuel pressure due to a possible bad filter or pump...

Here is a video of it trying to start, Notice i even gave new Dlephi glow plugs a good 10 seconds or so to warm and still same problem.



Anyone come across these symptoms before and if so any suggestions how to cure it..... Poor battery is takin a beating every morning....

Try starting it without a delay, don't wait for glow plugs just turn the key from the off of getting in the car, is the battery fully charged, maybe that the fuel pump is a bit lazy change the fuel filter as par the cause when you purchase any new/second hand car anyways.
