Before servicing any vehicle, please be sure to read the precautions section, which deals with personal safety, prevention of component damage, and important points to take into consideration when servicing a motor vehicle.

  1. Lift and support the intake manifold as outlined in the engine mechanical components section.
  2.  
  3. With support, install the J 45482 Debris Screen.
  4.  
  5. Disconnect the EI module harness connector.
    WARNING
    To avoid getting water and debris into the spark plug holes, use compressed air and shop rag to blow off the ignition module before the assembly is removed.


    NOTE
    Bolts can be screwed into the ignition module to aid when removing the module from the cylinder head.

Testing



Before servicing any vehicle, please be sure to read the precautions section, which deals with personal safety, prevention of component damage, and important points to take into consideration when servicing a motor vehicle.

When it is suspected that one or more spark plugs may not be firing and the spark plug wires do not seem to be at fault, this test offers a quick check to see if the ignition module and coil packs are producing spark voltage.


CAUTION
The DIS system produces extremely high voltages. Never disconnect or touch a system component while the engine is running or the key is in the RUN position. Furthermore, it is always safest to disconnect the negative battery cable before servicing any system components.

  1. Turn the ignition to the OFF position, then tag and disconnect all 4 spark plug wires from the ignition module towers.
  2.  
  3. Make sure that you are not touching the vehicle, then have an assistant crank the engine for a few seconds. Sparks should appear alternately between each pair of ignition coil towers while the engine is cranking.
    NOTE
    Do not crank the engine for more than a few seconds at a time or starter damage may occur. Crank the engine for a few seconds, then release the ignition key and pause for an equal amount of time before cranking the vehicle again.

  4.  
  5. If sparks appear between the 2 towers, the DIS module, Crankshaft Position Sensor (CPS) and the ignition coil packs are known to be good.
  6.  
  7. If a single coil pack is suspect from an initial spark test, or no sparks appeared between its 2 towers, switch the coil pack to the opposite position on the ignition module (the coil packs are interchangeable) and check to see if the problem follows it. If the problem follows, the coil pack must be replaced. If the formerly good coil pack does not produce spark when switched with the suspect coil on the module, and the suspect coil works in the new position, then the ignition module is bad and must be replaced. Also, using an ohmmeter, check the resistance across the suspect coil's towers; it should be 7,000-10,000 ohms.
  8.  
  9. If no spark can be found across any tower, proceed with the NO SPARK TEST.
  10.
