No power to the fuel pumps.
Bought a 1991 420sel. The fuel pumps don't pump. Checked with a multi-meter and no power to them. Any suggestions would be appreciated.
2 options: 1) do it yourself with a wiring diagram and a test light 2) find a good, honest Merc expert- you will need one, eventually-
You can try and replace the fuel pump relays and check your fuses........
This can be caused by a bad ground wire,if relay,s and fuse,s are good.
Change the fuel pump relay. I believe it's on the firewall. If you already changed the fuel pumps, the relay should be changed with it.
