Good evening all,

1990 Mercedes 560 SEL 231,000 miles. Been a few months since I replaced the fuel pump relay(used unit ). Moved the car yesterday and parked it. Went back to move the car a day later and no start. I tried jumping the relay for the fuel pumps. Did not make a difference. What else should I check before switching out the fuel pumps. Is there a way to tell if only one pump is back and not the other? I did get the car to start with starting fluid.

Is there a fuse related to the fuel pumps? Which one? I don't have the details sheets inside of my fuse box.

Any information/ suggestions would be greatly appreciated.

Ron
