Hi all seeking advice. Car intermittently idles rough and stops. Checks faults and has
1 fuel pressure regulator B control circuit open
2 fuel rail system pressure too low
3 fuel rail pump control valve stuck open
Just curious if anyone knows if these are related to the High pressure fuel pumps. If the regulator is located inside the high pressure fuel pump or somewhere else.
Again if the control valve is within the high pressure fuel pump
I have cleared the codes to see what comes back, but cannot trust as it comes out of nowhere.
