Hi everybody,
I see on FastLane the fuel pump relay is listed as 10 pin (6 and 4 per side)
Mine ('87 420 SEL) has only 9 pins (6 and 3). There is a hole in the receptacle where the 10 pin would go in, but it looks like no metal connector inside the hole.
Did MB change that relay and is the 10 pin the proper relay now for my car?
I have some stumble at idle and suspect the relay.
I tried to pry it open, but I'm afraid I'll break the black box before it comes out.
Thanks for your help.
