I did some search for you and found on some 525s the fuel pump relay and main relay are located in a box on right side of engine. the orange relay is the fuel pump relay, the white relay is the main relay and the other one is for the oxygen sensor heater. The fuel pump relay is the one in the middle. I am not so sure that this is applicable to your car. Does not hurt to try??? Sorry xgordyx I don't have the schematics for E34 . ANYONE OUT THERE??
