    So you have checked that power is getting to the contact on the cut-off
    solenoid. Have you checked that the solenoid is actually working? They do
    fail, either electrically, or stick mechanically.
    There is no immobiliser which will cut the power after you crank the
    If I remember correctly, the central locking on my '93 405 would also
    immobilise the starter. Unless you have some aftermarket system fitted.
    If you have fuel getting into the pump, but not out, how have you checked
    It sounds as if either the cut-off is stuck closed, or you have air in the
    To get the air out, you need to crack open the high pressure connectors on
    the top of two injectors. Then crank the engine with the accellerator pedal
    fully depressed.
    Keep cranking until you get fuel spurting from the connectors. You will
    probably see bubbles first.
    As soon as you get fuel, close those two and open the other two, and repeat.
    Then the engine should start normally, unless you have a leak allowing air
    to continually enter the fuel system.
