    Check the wiring diagram in the haynes.
    eg, the one for the Vectra (only haynes I have near me at the mo) says F22 (20a) goes to pin 16 of the diag socket.

    The one I have does, and it'd be unusual for a live feed not to pass through a fuse first.

    Re: no power at deignostics plug

    Sorry, Not sure what your diagnostic plug looks like, I can only check against a Calibra X20XEV plug. even this is all over the place in Haynes manual shown as X13 being the connector and which pin is which is hard to tell at a glance.

    I would think if your car is not starting then there could be a bad earth or some other electrical continuity problem including the ignition switch.

    are your dash lights on?, does it crank? and so on.

    Its still not bstarting then? I will need to go back to that thread and check out so far what has been tested and done and see if there is anything else that I can suggest a bit later on then.
