    If the pump runs when you lock or unlock, then if the locking is not working the chance are that you have a spit diaphragm in one of the doors or petrol flap. They will often be fine in one direction but not in the other.

    Reading your first post again I understand better,, inside the pump you have the change leaf type contacts, its possible that one is not making a good contact.



    coincidence ??? I have known it to happen, before anything else, make sure you key is working by pointing it into a camera where the beam should be seen

    sounds very like a key failure to me - does the spare work?
