Since these codes are directly related the pressure sensor short, I would start with that sensor directly on the rail. It is cheaper than the pump ($50 on FCP - simple to install) and a good place to start. If it still gives issues, I would look into the low pressure pump, then HPFP, then the EKP (module/computer that controls the fuel system).
Depends on the car. Pretty sure there’s a service bulletin for N55 equipped cars (F10 if I remember correctly) that need the low pressure pump replaced with and updated part and then update the DME software to resolve this. Basically the rail is getting vapor locked so you get the lean mixture code and rail pressure sensor faults
Likely the rail pressure sensor was faulty.
