Has anyone had this problem? There isn't an aftermarket alarm/immobiliser fitted to the car.
The car did run but one day stopped and i found a melted live (red) wire at the ignition switch so replaced that and the wire.
Any help is appreciated as its doing my head in now......
If you check at the connector where the loom connects to the car loom to make sure you are getting a switched 12v to the black wire when the ignition is turned on which will then power up the relays and you should get power at pin20.
