My 2010 Mini Cooper Clubman S, turbo, has low fuel pressure upon start-up. Engine dies and stumbles for a moment. Then, it picks up and runs well. I was occasionally having a loss of power at higher speeds, but changed the fuel filter and that problem has gone away. It acts like a bad fuel pressure regulator. I haven't measured the pressure at the fuel rail, but feel that it goes to zero after the car sits for a while. If you start up soon, it runs fine. IS THE REGULATOR BUILT INTO THE HPFP? Can it be fixed separately from the high pressure pump? Thank you so much.
