Leaking injectors or a failing check valve was my suspicion as well, just from general automotive experience.
I didn’t realize these cars monitor fuel pressure. I have bimmerlink with obd2 dongle, I believe that will display the pressure real time. If not, I will find a scanner that can do it.
If it is losing fuel pressure, I’m not sure how fast. It has no issue with hot starts.
I am out of town for week, but will report results this weekend.
Thanks,
Chris
