'89 560 SEC (W126) Wiring Scematic


<marquee> Please Help! </marquee>

I'm looking for a wiring scematic for a 1989 560 SEC. Just recently, the car fails to turn over, I believe it may be a fuel pump issue. I find it strange that both fuel pumps fail simultaneously, I guess it could be a fuse.

I am not a mechanic by any means, any help would be greatly appreciated.

Best Regards,

Post your question in the 126 forum – in that forum you can also search for ‘fuel pump relay.’ There’s a test to determine if the relay or pump(s) are bad.
