Setup and Installation
This section provides general guidelines for the installation of the MSD Street Fire 5526 Ignition Coil. For detailed, vehicle-specific instructions, always refer to your vehicle's service manual or consult a qualified automotive technician.
- Safety First: Before beginning any work, ensure the vehicle's ignition is off and the battery's negative terminal is disconnected to prevent accidental electrical discharge.
- Locate Existing Coil: Identify the current ignition coil(s) in your vehicle. The MSD 5526 is designed to replace factory-style coils.
- Disconnect Wiring: Carefully disconnect the electrical connector(s) from the existing coil. Note the orientation of the wiring if necessary.
- Remove Old Coil: Unbolt or unclip the old ignition coil from its mounting bracket. Keep any mounting hardware that will be reused.
- Install New Coil: Position the MSD Street Fire 5526 Ignition Coil in the same location as the old coil. Secure it using the provided hardware or the vehicle's original mounting hardware. The coil is designed to accept OEM connectors and brackets.
- Connect Wiring: Reconnect the electrical connector(s) to the new MSD coil, ensuring a secure and proper connection.
- Reconnect Battery: Reconnect the negative terminal of the vehicle's battery.
- Test System: Start the vehicle and check for proper operation. Listen for any unusual noises and observe dashboard warning lights.

Operation
The MSD Street Fire 5526 Ignition Coil operates as a direct replacement for your vehicle's original equipment ignition coil. Once properly installed, it functions automatically as part of the vehicle's ignition system, converting low voltage from the battery into the high voltage required to create a spark at the spark plugs. No user interaction is required for its operation beyond initial installation.

Maintenance
The MSD Street Fire 5526 Ignition Coil is designed to be a maintenance-free component. Regular inspection of the coil and its connections is recommended as part of routine vehicle maintenance. Look for:
- Physical Damage: Check for cracks, corrosion, or signs of overheating on the coil body.
- Secure Connections: Ensure all electrical connectors and mounting hardware are tight and free from corrosion.
- Wiring Integrity: Inspect the wiring leading to the coil for fraying, cuts, or insulation damage.
If any issues are observed, it is recommended to consult a qualified technician for diagnosis and repair.

Troubleshooting
If you experience issues after installing the MSD Street Fire 5526 Ignition Coil, consider the following common troubleshooting steps:
- No Start/Rough Idle:
- Verify all electrical connections to the coil are secure and properly seated.
- Check for proper grounding of the coil and associated components.
- Inspect spark plug wires for damage or improper connection to the coil and spark plugs.
- Ensure the coil is correctly mounted and not loose.
- Check Engine Light (CEL):
- If a CEL illuminates, retrieve diagnostic trouble codes (DTCs) using an OBD-II scanner. Codes related to ignition misfires (e.g., P030x) or ignition coil circuits (e.g., P035x) may indicate an issue with the coil or its wiring.
- Clear codes after addressing any identified issues and re-test.
- Coil Overheating:
- Ensure adequate airflow around the coil if its mounting location allows.
- Verify the vehicle's charging system is operating within normal voltage ranges. Over-voltage can stress ignition components.
If troubleshooting steps do not resolve the issue, it is recommended to seek assistance from a certified automotive technician or contact MSD technical support.
