hi there i hope some one out there can help me with this 05 plate d40 2.5dci. Truck starts and runs fine has got full power then you let it sit at tick over for a min[i.e in traffic or at a junction] try to pull away loss of power all the way through the gears stop engine restart pull away back to full power...
since this problem started the truck has had.
1.full service
2.MAF sensor
3. neutral switch disconected tryed and reconected
all thing that have tryed have not worked its also has not brought on the management light and the local nissan dealer is about as much use as a chocolate firegaurd because his little computer cant tell him what is the matter with it.


Replaced fuel pressure regulator on back of fuel pump and done fuel pump perameter reset. Now its all fixed. Pressure regulator ÂŁ130 from Nissan.

sounds like it could be the vacuum valve inside the diesel pump matey...

or if its happened after the service, air in the fuel lines if the fuel filter has been changed, have the fuel lines be put back on corretly and in the right order or even a pin hole in the fuel lines where the clamps are that hold it onto the fuel filter.
