Dead 325

My 93' 325i stopped running, the fuel pump will not turn on and I pulled a diagnostic code 1A (control unit supply). Checked the DME,Fuel pump, and O2 sensor Relays, checked the fuel pump itself and the DME control unit and all checked out O.K. Any advice or suggestions would be greatly apreciated. Thanks alot.:smoker2:

Have you checked the "DME Main" & "Fuel Pump" relays??? they're under a small cover just to the inside [engine side] of the 'E-box' [fusebox].
Keep in mind that if the control unit has NO B+, you wouldn't be able to scan it !
