F/RPS = Fuel/Rail Pressure Sensor
Those figures aren't right, should get about 3bar with ignition and ~280bar while cranking, as above. If you know someone with an HDi you can swap rail sensors with, that would be ideal, as it sounds as if yours is faulty.
Also, seems strange you've replaced the pre-heater and are still getting the TL4226 fault...
