Fuel Pressure Limiting Valve?

[ROH ECHT]

You still have your old HPFP? Is it OK so you could retry it? Or did you replace it hoping to fix this?
If the FPRV was it...the release of high fuel pressure data would look choppy, not smooth.

I installed the new pump, didn't fix the issue. I reinstalled my old hpfp.
