YES -
NO -
Go to Step 9 .
  1. Turn the ignition switch to LOCK (0).
  1. Check the No. 33 IGNITION COIL (15 A) fuse in the under-dash fuse/relay box.
Is the fuse OK?
YES -
Go to Step 11 .
NO -
Go to Step 12 .
Is the ignition coil relay OK?
YES -

  1. 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 IGNITION COIL (15 A) fuse, then go to Step 25 .
NO -
  1. Reinstall the ignition coil relay.
  1. Disconnect the ignition coil 3P connector from the problem cylinder.
  1. Turn the ignition switch to ON (II).
  1. Measure the voltage between ignition coil 3P connector terminal No. 3 of the problem cylinder and body ground (see table).
