Introduction

Ignition system issues can disrupt your car’s performance, causing misfires, poor fuel economy, or failure to start. Diagnosing and fixing these problems early can save you from costly repairs. This guide outlines common ignition system problems and how to address them using quality car ignition parts from MAPMS.

Common Ignition System Problems

• Misfires: Caused by faulty spark plugs or ignition coils, leading to rough idling or power loss.

• Hard Starting: Often due to a failing ignition switch or coil, making it difficult to start the engine.

• Poor Fuel Economy: Resulting from incomplete combustion due to worn components, increasing fuel consumption.

Diagnostic Steps

1. Check Engine Light: Use an OBD-II scanner to identify trouble codes related to the ignition system, pinpointing specific issues.

2. Inspect Spark Plugs: Look for wear, fouling, or damage, such as carbon deposits or electrode erosion.

3. Test Ignition Coils: Use a multimeter to check for proper voltage output, ensuring the coil functions correctly.

4. Examine Wiring: Ensure all connections are secure and free of damage to prevent electrical issues.

Fixing Ignition System Issues

• Replace Faulty Spark Plugs: Install new plugs matching your vehicle’s specifications to restore combustion efficiency.

• Replace Ignition Coils: Swap out defective coils with high-quality replacements to ensure strong sparks.

• Check Ignition Switch: Ensure it’s functioning correctly or replace it if needed to restore starting capability.
