Posted previously on incorrect board (sorry).. 1993 Subaru Loyale AWD Wagon (SPFI) with no spark condition. Tried new distributor, coil/power transistor assembly and ECU(used). 12 volts at both positive and negative coil connections which seems odd. Car was at dealer for repair and they couldn't fix it for lack of accurate electrical system diagram. Engine wiring diagram in FSM is functionally correct but many of the wire colors don't match. Any suggestions would be much appreciated...
