Well you have confused me with that pump location, the 2.2 DCi is a high pressure common rail system with the pump and suction control valve on the back of the engine

Okay, I'm referring to the one that sits in the fuel tank underneath the back seats I've heard it called the lift pump or Sender unit. This is the one I have ordered a replacement for as there was to fuel coming out of the outlet when the engine was being cranked.

it's not a pump but the fuel level sender to the gauge. I simply don't understand if the fuel pressure is meant to be OK if the primer does not work, except for air getting in the fuel line between tank and primer or primer and fuel pump on the back of the engine.
Have you tried the fuel pump reset?

I've just tried the Pump reset but no joy.

I am on a slight learning curve at the moment haha. Reading the ESM I was under the impression that there is a "Fuel level sensor unit, fuel filter and fuel pump assembly" Ref: FL-6.
   However this is with the exception of the YD22DDTI. Is the YD22DDTI the engine that is in the 2.2 DCI model? Or not.

If this is the case and there is no pump but just the sender unit in the fuel tank, does that mean that if I were to remove the out put line and crank the engine no fuel would emit from the sender unit as it requires suction to exit?

When the pressure was checked was via the ECU I believe as apposed to a guage on the lines.

Thanks for your patience

The YD22ddti is the low pressure turbo version of the DCi so they are not quite the same. Your second para assumption is correct. Start checking those line for splits, tears and loose connection points

Ahoy, almost a year late - however I thought I’d return to this post and summarise as I know people (inc myself) read through old posts to assist with fault finding and identify similar symptoms.

Long story short, the hand primer was faulty, along with misdiagnosed from the mech I called out... I was at a loss. Ended up taking her to a diesel specialist and it ended up being the SCV after all!

She's been running sweet since it was replaced and hopefully for many more years to come, many thanks again for D&G TS.
