I know that my fuel pump relay (green) is under the dash next to the steering column, along with the main ignition relay (brown) and another relay with a white plug. What is the white plug relay for?
Reason is that my car has not been starting. Have gone through everything, now just need to check that the fuel pump relay is working or not. What can I do to check this? Can I swap the relay that has the white plug with the fuel relay (they are both the same)?
