Mini P2848 fault code, no desired or actual fuel pressure reading

[goballdeep]

Hi I have a error code 2848 relating to fuel pressure I have had the diagnostic on the fuel pressure side and have no readings. I have checked the fuel pressure at 70 psi and checked the three wires to the fuel pressure sensor and have ground 12 and positive 5v and 5v. I have no change when it is plugged into the sensor. New fuel sensor also purchased. I have also had another ecu thinking it was that by having no diagnostic data. The car runs but stinks of fuel and has black dry soot coming out the back we’re the fuel sensor is not doing it’s job. The car is driving me crazy. When the trouble first started the car cut out dead and would not start. I’m wondering if I have a dodgy in tank fuel pump that works then not works.
