Im not understanding why you replaced the injectors and coils. Where they bad? Did you do a test on the injectors? It seems you wasted money and time without correct diagnosis.
I would put my bet on the HPFP and Low pressure fuel sensor. Change those two out and your issue should be fixed.

I went to the bmw dealer so they can run a diagnostic to see what was wrong with the car and they end up telling me that I had a misfire on cylinder 2 and 5 and that I need to change my spark plug and coil to see if that fix the problem and if the problem keep happening then I need to replace my 2 and 5 so I end up just replace all of them at ones.. But my problem keep happening and when I use my obd tool it says CYLINDER CUTOFF BANK 1. So I don't if a hpfp problem or what?
