I have 1993 Mercedes SL500. I have no power going to the fuel pumps. I traced and found the problem , it was a relay controller behind the Passenger seat in the compartment. This controller has many relays embedded inside.. Does any one have the actual name and the part number for this controller? and any Schematics....

The controller you traced to is the one for the convertible top. It has nothing to do with the fuel pump, of course. Your car's fuel pumps arecontrolled by the ESCM module. You really ought to invest $75 in the R129 Tech DVD from MBUSA. It has all the schematics, repair procedures, and diagnostic manuals for your car.
