If it was running ok before you parked it up for a week, I would suggest it's highly unlikely "all" the injectors have suddenly failed. When the PRV goes, it usually does it suddenly....however, it's normally the SCV which causes the PRV to blow...I'm not saying this is your issue but the symptoms point to it.
If one or both the valves are replaced, the learns will need doing and your garage will need the right kit to do it.

Im going to get some new denso injectors sent to garage and have them fitted. Please can you tell me if i need or it would be advisable to have the PRV and SCV done at same time, they may or may not be good/bad. trying to keep a lid on costs but prefer little pain now than a lot later if worth doing what ever state they are in.

If the pump was duff it would fail the pump learn part of the process and IDS will abort the rest of the learns, these Mk7 TDCi pumps rarely fail. Do you know it the SCV and PRV are genuine Ford items..? We've had issues with a lot of non-genuine valves not passing the learns. If the learns fail three successive times the PCM will often go into limp mode, I'm not suggesting this has happened, but it is a possibility...just me thinking out loud.
Also, the new injectors need "coding in" as they each have their own calibration correction factors...I would assume this has been done though.??

yes genuine ford parts according to PFJones, brand new PRV/SCV and brand new injectors all from PFjones. no idea if garage done all learns and software etc correct and well but have to take their word they did. curious if not what the symptoms of it would be. how can i find out whats now at fault without just taking out and replacing new part after part after part until found.?
