Check for voltage at control unit connector (Blue and Black/Yellow wires) with ignition on. If there is no voltage at Black/Yellow wire, check wiring. If there is no voltage at Blue wire, check wire between ignition coil and control unit. Check Brown/Black wire for continuity between control unit and ground. There should be continuity. Check wiring and fuse between control unit connector (Blue/White wire) terminal and ignition switch start terminal.
