Does the engine run at all?
Put 2 gal of gas in tank to rule out a tank level gage problem.
Remove and reinsert all coil connectors.
I think "rail pressure" is the measured value and "nominal value" is the target/expected value. Your fuel pressures seem low.

N55 may be different, but when I unlock my E70 N52 or open door after being asleep, the fuel pump primes. We need to confirm the LPFP is delivering ~5barg. Check fuel pressure after unlocking and before cranking using scanner. If you can't see it thru scanner, my N52 has Bundy fittings near brake booster that allow a pressure gage to be connected to the LP side of the HPFP.

Does Foxwell allow you to run the LPFP?
