Here's a general outline; you'll need a socket set, possibly a wrench, and possibly some needle-nose pliers. Consult a 1989 Ford Ranger repair manual specific to your engine for precise locations and diagrams:
1. Locate the Ignition Module: This is usually mounted on the distributor or on the firewall near the distributor. The location varies by engine type. Your repair manual is crucial here. The module itself is usually a small, rectangular black box.
2. Disconnect the Electrical Connectors: Carefully unplug the electrical connectors attached to the ignition module. These are usually held in place by a locking mechanism. Gently push and/or pull on the connector to release it. Sometimes a small tab needs to be pressed to allow for disconnection. Take pictures or make a diagram before disconnecting anything to ensure proper reassembly.
3. Remove Mounting Hardware: The ignition module is usually held in place with one or more bolts or screws. Use the appropriate socket or wrench to remove these fasteners.
4. Remove the Module: Once the fasteners are removed, carefully remove the ignition module from its mounting location.
Important Considerations:
* Engine Type: The exact location and access method will vary slightly depending on whether you have a 2.3L, 2.9L, or a 4.0L engine. A repair manual is essential for accurate instructions.
* Fragile Connectors: Be gentle when disconnecting the electrical connectors. Damaged connectors can lead to ignition problems.
* Grounding: Ensure you're working in a clean, dry area to avoid short circuits.
* Repair Manual: A factory service manual or a reputable aftermarket repair manual specific to your 1989 Ford Ranger is highly recommended. It will provide detailed diagrams and instructions for your particular engine.
If you are uncomfortable performing this task yourself, take your vehicle to a qualified mechanic. Improperly handling the ignition system can lead to damage or injury.
