Need Fault Code Help

2be9 cylinder injection cutout: pressure too low in high-pressure fuel system.

I am fbo e50 with stage 2 lpfp

Went wot in 2nd and engine just stopped. Stalled out a few seconds after. Wouldn't start with a long crank. Fueling system is 100% the issue just don't know what part. Thinking lpfp or hpfp. If anyone has some advice I'm desperate!

Only happens on hard throttle. I'm chilling everywhere else

Sounds like your HPFP. I'd also replace the pressure switch in the fuel rail just after the pump. I know you have codes but...

Sure it's not your charge pipe ? Btw... N54 or N55 ?

N55
Charge pipe is made of aluminum. I was just driving along and went wot in 2nd and at like 4K rpm the fueling just completely cut out, car stuttered then stalled when I stopped. My high pressure pump has always been solid even during the times nothing else worked so I really don’t think it is the hpfp. Is there any way to test the hpfp or lpfp? Besides data logs because if it is just the logs my hpfp has always been 100%, can’t log lpfp in n55.
