WARNING: This page is about a different car, the 1996 Mercury Villager and 1995 Mercury Villager. However, it is still accessible from the selected car via links, so may be relevant.
  1. Disconnect ignition coil wiring harness connector. Turn ignition on. Measure voltage between connector Blue/Yellow wire terminal and ground. If voltage is 10 volts or more, go to next step. If voltage is less than 10 volts, repair Blue/Yellow wire circuit.
  2. Turn ignition off. Measure resistance between ignition coil primary terminals. Resistance should be 1.4-1.6 ohms. Measure resistance between ignition coil positive primary terminal and secondary terminal. See Fig 1 . Resistance should be 9800-10,000 ohms. If resistance is not as specified, replace ignition coil. If resistance is as specified, go to CIRCUIT TEST IGNS in the TESTS W/CODES article.
