4. Setup and Installation

Installation of the HEI Ignition Control Module requires basic automotive electrical knowledge and tools. If you are unsure about any step, it is recommended to seek assistance from a qualified automotive technician.

4.1 Safety Precautions

• Always disconnect the vehicle's battery before beginning any electrical work to prevent accidental shorts or injury.
• Ensure the engine is cool before handling ignition components.
• Wear appropriate personal protective equipment, including safety glasses and gloves.
• Avoid touching hot engine components during and after operation.

4.2 Installation Steps

1. Locate the HEI Distributor: Identify the HEI distributor in your vehicle. The ignition control module is typically located inside the distributor housing, often beneath the rotor and cap.
2. Remove Distributor Cap and Rotor: Carefully remove the distributor cap and rotor to expose the internal components.
3. Disconnect Old Module: Disconnect the electrical connectors from the existing ignition control module. Note the orientation of the wiring.
4. Remove Old Module: Unscrew or unclip the old module from its mounting location.
5. Apply Thermal Paste (if necessary): If the new module does not come with pre-applied thermal paste, apply a thin, even layer of dielectric grease or thermal paste to the metal base of the new module. This aids in heat dissipation.
6. Install New Module: Position the Allstar Performance ALL81208 module in the distributor housing and secure it with the appropriate fasteners.
7. Reconnect Wiring: Reconnect all electrical connectors to the new module, ensuring they are firmly seated.
8. Reinstall Rotor and Cap: Replace the rotor and distributor cap, ensuring they are correctly aligned and secured.
9. Reconnect Battery: Reconnect the vehicle's battery.
10. Test System: Start the engine and check for proper operation. Verify that the engine runs smoothly and without misfires.

Refer to your vehicle's specific service manual for detailed instructions regarding distributor removal and installation procedures, as these may vary by vehicle model.

5. Operation

The Allstar Performance ALL81208 HEI Ignition Control Module is an integral part of your vehicle's ignition system. Once correctly installed, it operates automatically to manage the timing and duration of the spark delivered to the spark plugs.

• Function: The module receives signals from the magnetic pickup coil within the distributor, interprets engine speed and position, and then triggers the ignition coil to produce a high-voltage spark at the precise moment required for combustion.
• Performance: This high-performance module is designed to provide consistent and strong spark delivery, contributing to efficient engine operation and improved combustion.

No user interaction is required for the module's operation after proper installation. Its function is entirely electronic and internal to the ignition system.

6. Maintenance

The Allstar Performance ALL81208 HEI Ignition Control Module is a sealed electronic component and requires no routine maintenance. However, ensuring the overall health of your vehicle's ignition system can prolong the life and performance of the module.

• Keep Connections Clean: Periodically inspect the electrical connections to the module and distributor for corrosion or looseness. Clean any corrosion and ensure connections are secure.
• Check Distributor Cap and Rotor: Regularly inspect the distributor cap and rotor for cracks, carbon tracking, or excessive wear. Replace them as needed.
• Spark Plug and Wire Inspection: Ensure spark plugs are in good condition and properly gapped. Inspect spark plug wires for damage or degradation.
• Thermal Paste: If the module was removed for any reason, ensure that fresh thermal paste is applied upon reinstallation to maintain proper heat dissipation.

Avoid exposing the module to extreme moisture or harsh chemicals. Do not attempt to open or repair the module, as this will void any potential warranty and may damage the component.

7. Troubleshooting

If you experience issues with your vehicle's ignition system after installing the ALL81208 module, consider the following common troubleshooting steps. Always ensure safety precautions are followed before attempting any diagnostics.

7.1 Common Issues and Solutions

• Engine Cranks but Won't Start (No Spark):
  • Check Connections: Ensure all electrical connections to the module, coil, and distributor are secure and free of corrosion.
  • Verify Power: Confirm that the ignition coil and module are receiving proper voltage when the ignition is on.
  • Test Pickup Coil: A faulty magnetic pickup coil in the distributor can prevent the module from triggering a spark. Test its resistance according to your vehicle's service manual.
  • Module Failure: While designed for durability, electronic modules can fail. If other components test good, the module may be faulty.
• Engine Misfires or Runs Roughly:
  • Check Spark Plugs and Wires: Worn or damaged spark plugs and wires are common causes of misfires.
  • Distributor Cap/Rotor: Inspect for cracks, carbon tracking, or excessive wear.
  • Timing: Incorrect ignition timing can cause rough running. Verify timing is set correctly.
• Engine Stalls Intermittently:
  • Heat Related Issues: Ensure proper thermal paste application. Excessive heat can cause intermittent module failure.
  • Loose Connections: Vibrations can loosen connections, leading to intermittent power loss.

For advanced diagnostics, consult a professional automotive technician or refer to a comprehensive vehicle service manual. Do not attempt repairs beyond your skill level.
