MOT Result & Fault

[johnboy]

also dont know if its worth mentioning but sometimes the faults go away then other times they reappear, but if you boot the car it goes into limp mode, but is perfectly fine driving under 60 odd below 3000rpm

just that the fuel pressure is within the correct range mate, that would prove the pump. You say the rail sensor was replaced? The codes could be old, and just need cleared...

ah ok, didnt see your last post till i sent mine.

Booting it would drop the fuel pressure if the pump cant keep up with demand, then clear when the rail pressure rises again when you slow down....

I am starting to think the pump is failing but its only an educated guess till your under-load fuel pressure is measured.

yea now you say it i guess it is possible the pump could be on its way out.

It was the fuel pressure regulator i replaced so im guessing it is ok.
