Ignition system repair

Is your car cranking but refusing to fire up? Don’t get stranded! Ignition system problems can leave you at a standstill. Our mechanics are experts at diagnosing and repairing all aspects of your car’s ignition system, getting you back on the road quickly and reliably.


    Difficulty Starting

    The most common symptom is the engine cranking but not starting, or taking multiple attempts to crank before starting.

    Rough Idling

    The engine vibrates excessively at idle due to misfires caused by weak spark or improper timing.

    Engine Stalling

    The engine may stall while driving due to misfires or complete spark failure.

    Reduced Engine Performance

    Ignition system problems can lead to a loss of power and acceleration due to inefficient combustion.

    Check Engine Light

    Modern vehicles often trigger the check engine light when the engine computer detects problems with the ignition system.

    Faulty Spark Plugs

    These are responsible for igniting the air-fuel mixture in the engine’s cylinders. Over time, spark plugs can wear out, become fouled with deposits, or have improperly gapped electrodes. This can lead to weak spark or misfires, causing difficulty starting, rough idling, and reduced engine power.

    Malfunctioning Ignition Coils

    The ignition coil steps up the voltage from the car’s battery to create the high voltage spark needed by the spark plugs. A failing coil can deliver insufficient voltage, resulting in weak spark and starting problems.

    Ignition Switch Issues

    The ignition switch is the component you turn to start the engine. A worn-out switch or electrical problems within the switch can prevent it from sending the necessary signal to start the engine.

    Distributor Problems (Older Vehicles)

    In older vehicles with distributor-based ignition systems, problems with the distributor cap, rotor, or sensor can disrupt the proper timing and delivery of spark to the cylinders.

    Sensor Faults

    Various sensors in the engine, such as the crankshaft position sensor or camshaft position sensor, provide crucial information to the car’s computer for proper ignition timing. A faulty sensor can send incorrect signals, leading to ignition timing issues and engine performance problems.

    Corroded Battery Terminals

    While not directly part of the ignition system, corroded battery terminals can impede the flow of electricity needed to power the entire system, including the spark plugs and ignition components.

    The key players in your car’s ignition system include:

    • Battery: Provides the electrical power needed for the entire system.
    • Ignition switch: Activates the system when you turn the key.
    • Ignition coil: Converts the battery’s low voltage into high voltage electricity for the spark plugs.
    • Spark plugs: Deliver the high-voltage spark to ignite the air-fuel mixture in the engine cylinders.
    • Distributor (in some cars): Routes the high voltage electricity to the correct spark plug at the appropriate time. (Modern cars often use coil-on-plug systems without distributors)

    When you turn the key, the ignition switch sends a signal to the battery, which supplies electricity to the ignition coil. The coil transforms this low voltage into a high voltage current. In cars with distributors, this high voltage electricity travels through the distributor, which directs it to the correct spark plug based on the engine’s firing order. In modern cars with coil-on-plug systems, the high voltage electricity travels directly from the coil to each spark plug. Finally, the spark plugs ignite the air-fuel mixture in the engine cylinders, creating the combustion that powers your car.

    Several symptoms might indicate trouble with your ignition system:

    • Difficulty starting: The engine might crank but struggle to turn over, or multiple attempts might be needed to start the car.
    • Engine hesitation or stumbling: The engine might sputter or hesitate during acceleration or while maintaining a steady speed, due to inconsistent spark delivery.
    • Rough idling: The engine might vibrate excessively at idle due to improper combustion caused by weak spark.
    • Reduced fuel economy: A faulty ignition system can lead to inefficient fuel burning, resulting in lower gas mileage.
    • Check Engine Light illumination: The Check Engine Light might come on, potentially indicating a problem with the ignition system.

    A typical ignition system repair session might involve:

    • Diagnosis: The mechanic will use a scan tool to retrieve trouble codes and assess engine performance data.
    • Visual inspection: They’ll visually inspect the ignition system components for signs of wear, damage, or corrosion.
    • Testing: Components like spark plugs and ignition coils might be tested to assess their functionality.
    • Repair or replacement: Based on the diagnosis, the mechanic will recommend repair or replacement of the faulty components.

    Repair times depend on the complexity of the issue and the components involved. Simple repairs like replacing spark plugs might take less than an hour, while diagnosing and replacing a faulty ignition coil could take up to a few hours.

    • Costs can vary depending on labor rates, the specific components needing replacement, and the complexity of the repair. Spark plug replacement can be relatively inexpensive, while replacing an ignition coil might cost more.

    • Regular maintenance: Following the manufacturer’s recommended maintenance schedule ensures timely replacement of spark plugs and other critical components.
    • Use high-quality spark plugs: Cheap spark plugs can wear out faster and lead to problems.
    • Avoid fouled spark plugs: Certain engine issues or low-quality fuel can foul spark plugs, preventing proper sparking. Address any underlying engine problems and consider using fuel injector cleaners periodically (consult your owner’s manual).
    • Coil-on-plug (COP) systems: These eliminate the need for distributors by placing an individual ignition coil directly on top of each spark plug for a more precise and efficient spark delivery.
    • Direct Ignition (DI) systems: In some modern engines, the spark plugs are located directly within the combustion chamber, allowing for more precise ignition timing and improved engine efficiency.
    • No spark at all: If the engine cranks but doesn’t even attempt to start, it could indicate a complete failure in the ignition system.
    • Strong electrical burning smell: This could signify a short circuit or overheating within the ignition system, requiring immediate professional attention.
    • Visible damage to ignition system components: Cracked, worn, or corroded components pose safety risks and should be addressed promptly.
