ELECTRICAL PROBLEM 1
Problem - Fuse no 18 on the main board has blown and there is a short to ground somewhere on this circuit. This fuse serves the central locking, fuel flap, and some element of the electronic ignition. With this fuse gone, the fuel pumps don't cut off at start up, but car runs ok. I have disconnected the motors for the central locking and the fuel flap, but the short to ground is still there. Car is a 1991.
Possibility 1 - The best way to go about this is to pull the fuse, open the fuse box panel, note the wire colors going to it. Switch on the ignition. Find the +12 V pole of the fuse then from the other pole measure resistance to ground. If it is 0 you have a short. Disconnect the same colored wire at fuel pump see if the wire still goes to ground, if not then the other side of the fuel pump etc. Follow the wires as best you can around the car. If it is a transient loose wire rubbing occasionally against the frame it will be a real pain to identify!
