    Hey has a b180 cdi with om651 engine. The problem arose after the tensioner for the chain had to be replaced and after that it did not want to start.
    Check and it is still good in markings.

    no error codes has found

    I have found a problem and it is that the fuel pressure is 270bar when you turn on the ignition but when you turn the engine, the fuel pressure almost completely disappears. Any ideas?

    Hi
    Where did you connect the pressure gauge?
    What is the mileage on the engine?

    Hi thanks for reply!
    I have used delphi computer.

    The car went perfectly before but rattled by the tensioner.
    The car has gone far 40.0000km
    I hear that the pump is working in the tank, stands on the computer about 4bar thank you for answering!
