This sounds like your high pressure pump its a common problem so do no worry.

you can check this by removing your air box you need to remove 2x8mm nuts at front and 1x10mm nut at rear to remove air box next disconnect and remove air box


now you can see clearly you should be able to get to the part its located on the right hand side if looking at van from the front end


The valve is a 17mm nut .Remove the diesel relief pipe from the valve ( normally held in place by a clip, push in red tab to release... Unwind the valve with 17mm spanner. If upon removing the valve you find that you have 'several bits' this means that the valve is damaged and needs replacing



please note this cant be replaced yourself you must go to ford as the computer will need an update after otherwise you will break the new part if done before the software update... if you find their is no faulty part an update alone will fix it





I hope this help and if I can assist you further please let me know


Thank you

hi dan,there is nothing under the air box,the fuel pressure release vale is on the end of the common rail,a new no.2 injector has cured the starting problem but we still have an uneven tick over albeit intermiant

Expert:  dansgarage1 replied 4 years ago.



I am happy you have almost fixed your problem I was convinced it would be the fuel pressure valve as so many transits are coming in with this problem at the moment


that's right the sensor on the fuel pressure rail was what I was talking about.


did you replace this or check it for faults? as many transits are coming in now with this problem


also did you have the software update done?


and also one last thing you can try if it ticks over is bad now and then is the clutch switch this is behind the dash and your clutch controls the switch if you remove the switch when your stationary don't drive off but see how it ticks over without that switch in


if I can give you more help please let me know



Many Thanks
