Mercedes: 1990 420 sel, fuel pump relay, number search results

Question
i have a no start problem with a 1990 mercedes 420sel
i have no power at the fuel pumps
the car will start with 2+2
i cant find a fuse location for the pump or a relay


Answer
If I recall correctly, it is "in front of" the passenger bulkhead, hiding behind the battery and a plastic dust shield.
The battery must come out, and a STRONG light will help find the relay.
Replace the "Overload Relay" at the same time.
