Then I took the car for a drive and recorded a log. As you can see....as soon as I rolled into the throttle, the HPFP pressure started to climb, all of a sudden it took a dump and fell to 400psi....causing another 29DC injector Cutoff fault.

Is this what happens when a HPFP starts to fail? Or is something else going on? It's odd how it fires up and idles fine....but as soon as you put a load on the motor and the pressure starts to built....it just falls on its face. Replace the HPFP??

Just an update....it turned out to to be the HPFP. Ordered a new one from FCP....cara running like a champ again.
