Testing



3.0L Engine
  1. Disconnect the negative battery cable.
  2.  
  3. Remove the ignition coil cover
  4.  
  5. Disconnect the ignition coil harness connector from the coil.
  6.  
  7. Connect ohmmeter leads to ignition coil pins 1 and 2. The resistance should be approximately 1 ohm. If the resistance is outside of specifications, replace the coil. If it is within specifications, continue by testing the secondary winding resistance.
  8.  
  9. Disconnect the coil wire from the coil.
  10.  
  11. Connect the ohmmeter leads to coil pin 1 and the coil wire tower. The resistance should be approximately 10,000 (10k) ohms. If not, replace the coil.
