No fuel pressure.

No fuel pressure.
I parked my 2008 R55 yesterday, and it will not start this morning. Pulled the back seat to see if I could hear the fuel pump running at startup, and nothing. Oddly, after turning the engine over a few times and then pressing the start/stop button again, the fuel pump relay makes and the pump will kick on about 10 seconds later and run briefly. I've read lots of issues with the fuel pump relay on the JBE, but this one seems to work fine - just not when I need it to! Good pump, good relay, non-starter. Anybody have any ideas here?

I have 2007 “S” and I have no prime which sounds like your problem. With key/ fob in fuel pump should come on 3 - 5 seconds and prime fuel system. My fuel pump works on crank and run but no initial prime which results in hard / no start. I have a post on here for “no prime signal to fuel pump” but no responses for wiring diagram to see where fuel pump relay gets it’s prime signal.
