Fuel pump keeps running on 280SE
 

I have a 1982 Australian (right hand drive) 280SE W126.
The fuel pump continues to run even when the ignition is off, eventually running the battery flat. I have pulled all the relays I can find, but it still runs with them all out. What can I look at to trace the problem?

Should be just one relay that controls that. A wiring diagram will help too. There are some parts houses that have a 'where is the part' help section too.

Welcome to forum. Im sure someone who knows will pop in.
