  13. Disconnect all ignition coil 3P connectors.
  14. Check for continuity between No. 1 ignition coil 3P connector terminal No. 3 and body ground.

    Is there continuity? 

    YES:  Repair short in the wire between the ignition coils and the ignition coil relay. Also replace the No. 33 IG COIL (15 A) fuse, then go to step  25.

    NO:  Check the under-dash fuse/relay box, and replace it if needed (see REMOVAL AND INSTALLATION ), then go to step  25.
