Hello !
I have a C class 2.7cdi . When I leave the car overnight it refuses to start in the morning , until I force it to start with an easy start spray ( which I believe is not very good for the engine ) . After that during the day it cranks 5 6 times before firing up . Yesterday as I was driving the car just shut off . I had the injectors checked , none of them is leaking . I had a computer diagnostic check yesterday and it says rail pressure fault . Is this the high pressure fuel pump problem or common rail issue ?
Thank you
