Check the contacts on the rail pressure sensor.

Start at the beginning.. Have you had the suction screen out of the fuel tank?? Changed the filters, checked the hoses etc??

Hi
Yeah I've replaced all the hoses and it's been serviced 60 hours ago, had the screen out the tank back end of last year and that was clean

Is the O-ring in place between the primary filter and the glass bowl??
Are there any error codes??
Have you tried it on a dynamometer??

Yes mate replaced the o ring when I serviced it brought a proper one from jd dealer, not sure about error codes did find one a while ago cant remember the code but I no it meant problem with the fuel supply
