scudo cutting out at idle

Hi i have a scudo common rail that cuts out at idle, the mil light is on and the code is connected to low fuel pressure, it will keep running when the revs are high and when it cuts out the tank pump doesn't run. if i keep putting the ignition on the pump will run and it starts only to cut out again. is there a pressure valve that is faulty? and if so where is it? i dont have any wiring info on it.

Hello mate i am i newbie to the forum but i would suggest that you try fuel pump relay which is situated under bonnet right hand upper corner in a plastic box there are two blue relays it is the one on the right 12 volt 45 amp cheers hope this helps!
