    14.  

  6.  
  7. Connect the negative battery cable.
  8.  


NOTE
Two ignition coil packs are used, one for each bank of cylinders. This procedure is for removing 1 ignition coil pack, but the procedure remains the same for either side.

  1. Disconnect the negative battery cable.
  2.  
  3. Detach the ignition coil and radio ignition interference capacitor electrical harness connectors.
  4.

Testing



Primary Winding Resistance
  1. Turn the ignition OFF .
  2.  
  3. Disconnect the negative battery cable.
  4.

Fig. Testing the primary ignition coil resistance-4.6L engine

  1. Disconnect the wiring harness from the ignition coil.
  2.  
  3. Check for dirt, corrosion or damage on the terminals and repair as necessary.
  4.  
  5. Measure coil primary resistance between ignition coil pin 2 (B+) and pins 1 (coil 2), 2 (coil 3) and 3 (coil 1).
  6.  
  7. Resistance should be 0.3-1.0 ohms. If resistance is out of specifications, replace the coil pack. If resistance is within specifications, proceed to secondary windings testing.
  8.  

Secondary Winding Resistance
  1. Measure coil secondary resistance between the corresponding spark plug wire towers on the coil.

    Coil 1-cylinders 1 and 6
     
    Coil 2-cylinders 3 and 5
     
    Coil 3-cylinders 4 and 7
     
    Coil 4-cylinders 2 and 8
