Repair Guide: Nissan Skyline GT-R (1996) - Coil Pack Failure

This guide will detail the process to diagnose and repair a problem commonly associated with the 1996 Nissan Skyline GT-R: Coil Pack Failure. While Skyline is a reliable model, especially for its contributions to automotive technology in the 90s, this particular issue could impact the performance of the vehicle if left untreated.

Tools Needed

Diagnostic Steps

  1. Start by identifying the symptoms. This may include rough idling, decreased fuel efficiency or a lack of power when accelerating.
  2. Next, use a multi-meter to measure the resistance on the coils. If the reading is outside the manufacturer's specification (1-10 ohms for most coil-on plugs), then the coil pack is faulty and needs replacing.

Repair Steps

  1. Once diagnosis is complete and a faulty coil pack has been identified, the first step in the repair process is to disconnect the negative terminal on the battery. This ensures there is no power going to the coils during the replacement procedure.
  2. Next, remove the old coil pack by disconnecting the connector cable and removing the bolts using the socket wrench.
  3. Once the old coil pack is removed, put a little dielectric grease on the inside of the boot on the new coil pack, this prevents misfires and ensures optimum performance.
  4. Install the new coil pack by aligning it with the plug, securing it with the bolts and reconnecting the connector cable. Remember not to overtighten the bolts, as this could cause damage.
  5. After all new coil packs are installed, reconnect the negative terminal on the battery.

Potential Pitfalls and Tips

  1. A common pitfall when replacing coil packs is not diagnosing the issue accurately. Ensure that all tests are conducted thoroughly to ensure the fault lies with the coil pack and not another part of the ignition system.
  2. Ensure that all connections are clean, and any corroded wires or connectors are replaced at the same time as the coil pack to prevent problems in the future.
  3. Use dielectric grease on the boot of the new coil on plug to ensure a solid connection and prevent misfires.
  4. Do not overtighten any cables or bolts to prevent damage to the new coil pack.

Conclusion

By following these steps, you should be able to successfully replace a faulty coil pack on your 1996 Nissan Skyline GT-R. Remember to always put safety first, and if you are unsure seek the help of a professional mechanic.
