    Is there continuity? 

    YES  -Repair a short in the wire between the ignition coils and the ignition coil relay. Also replace the No. B11 IG COIL (15 A) fuse, then go to step  26.

    NO  -Check the under-hood fuse/relay box, and replace it if needed (see REMOVAL AND INSTALLATION ), then go to step  26.

  16. Reinstall the ignition coil relay.
  17. Disconnect the ignition coil 3P connector from the problem cylinder.
  18. Turn the ignition switch to ON (II).
  19. Measure the voltage between ignition coil 3P connector terminal No. 1 of the problem cylinder and body ground (see table).
