Hi have just fitted new diesel filter to my 03 3.0 and it will now not start have primed it and still no joy .
Battery is now flat so am charging up .:doh
Did you remove the two hoses to change it? I had to when I did mine and it took a little bit of starting. I also filled the new filter up with fuel before fitting as per the club download, which I can see would help.
You could try taking a hose off at a time of to see if fuel is present i.e the pumps working.
Years ago we used to bleed the injectors on deisel forklifts at work. I am not sure if you can do this on the terrano engine though.
