1. Safety First:
* Disconnect the negative battery cable before starting any work. This is crucial to prevent electrical shocks and accidental damage.
2. Locate the Ignition Module:
* The ignition module is usually mounted on the distributor or very close to it. It's a small, rectangular or square electronic component. Refer to your vehicle's repair manual (a Haynes or Chilton manual would be ideal) for the exact location and picture. This is the most important step – a wrong location can lead to unnecessary disassembly.
3. Access the Module:
* Depending on its location, you might need to remove some components to gain access. This could include:
* Air cleaner assembly: Often needs to be moved out of the way.
* Intake components: Possibly some vacuum lines or other parts obstructing the view.
* Distributor cap: Sometimes the module is mounted directly on the distributor, requiring cap removal.
4. Disconnect Electrical Connectors:
* Carefully unplug any electrical connectors attached to the ignition module. These are usually simple push-on connectors. Gently pull them straight off; avoid bending the wires. Take a picture or make a note of how they're connected for reassembly.
5. Remove Mounting Bolts or Screws:
* The ignition module is typically secured with one or more bolts or screws. Use the appropriate size socket or screwdriver to carefully remove these fasteners.
6. Remove the Ignition Module:
* Once the fasteners are removed, gently pull the ignition module away from its mounting location. Be cautious of any fragile wires or connectors.
7. Reassembly:
* Reassembly is the reverse of the removal process. Make sure all connectors are securely plugged in and all fasteners are tightened properly. Reconnect the battery's negative cable.
Important Considerations:
* Repair Manual: This is essential. It will provide accurate diagrams, torque specifications, and specific instructions for your vehicle's engine. Attempting this without a manual is strongly discouraged.
* Photography: Take plenty of pictures during the disassembly process. This will be invaluable when putting everything back together.
* Careful Handling: The ignition module is sensitive to physical damage. Avoid dropping it or applying excessive force during removal or installation.
* Replacement: If you're replacing the module, ensure you get the correct replacement part for your specific vehicle's engine. The part number should be clearly visible on the old module.
If you're not comfortable performing this repair yourself, it's best to take your vehicle to a qualified mechanic. Improperly handling the ignition system can lead to serious problems.
