Please tell me you haven't broken into the fuel rail or cracked off any injectors? It's high pressure common rail and requires specialist equipment to discharge safely and re-pressurise afterwards.
and i cheked injector if they have fuel by loosing that nut thats electrik told me to do hen hes cheked hy my car didint start
Which nut did you loosen? Were you told to by a qualified mechanic?
You should NEVER loosen anything on a high pressure fuel system. You bleed the system by operating the starter for 10-15 seconds several times until the engine fires. Chances are you've now lost all pressure in the common rail.
