Zero other faults or codes.
Not flashed.
As I mentioned already tried a known good EKP and same issue.
When car starts, pressure is around 6 bar, then bleeds down to 3.6 bar for 1.5 minutes then shoots up to 7 bar, just before the start/ warm up procedure ends.
Nothing apart from some service work, plenum came off about a dozen times chasing an air leak on one of the boots is all.
Sensor Wiring checked as good.
I'm leaning towards the pump, as in the screen shot from INPA you can see on top right it's not reading in the correct zone for fuel flow (230L/hr) my reasoning is due to not enough flow the DME/EKP is requesting a higher pressure to compensate.
Only thing I haven't checked for is a damaged fuel line, maybe something got damaged when on the lift
