Red Spark from Coil: A Sign of Ignition System Trouble

The ignition system is a vital part of your car's engine. It is responsible for providing the spark that ignites the air/fuel mixture in the cylinders, causing the pistons to move and the engine to run. If the ignition system is not working properly, your car will not be able to start or run.

One of the most common signs of ignition system trouble is a red spark from the coil. This can be caused by a variety of problems, including:

• A bad spark plug wire


• A bad distributor cap or rotor


• A bad ignition coil


• A bad ignition control module

If you see a red spark from the coil, it is important to have your car inspected by a qualified mechanic as soon as possible. Driving with a faulty ignition system can cause serious engine damage.

Symptoms of a Bad Ignition System

In addition to a red spark from the coil, there are a number of other symptoms that may indicate a bad ignition system, including:

• Engine misfires


• Rough idling


• Stalling


• Reduced fuel economy


• Increased emissions

If you experience any of these symptoms, it is important to have your car inspected by a qualified mechanic as soon as possible.

Causes of a Bad Ignition System

There are a number of factors that can cause a bad ignition system, including:

• Wear and tear: The ignition system is a complex system with many moving parts. Over time, these parts can wear out and need to be replaced.


• Heat: The ignition system is exposed to a lot of heat from the engine. This heat can damage the components of the ignition system and cause them to fail.


• Moisture: The ignition system is also exposed to moisture from the air. This moisture can cause the components of the ignition system to rust and corrode, which can lead to failure.

Preventing Ignition System Problems

There are a number of things you can do to prevent ignition system problems, including:

• Regular maintenance: The best way to prevent ignition system problems is to have your car serviced regularly by a qualified mechanic. A mechanic can inspect the ignition system and replace any worn or damaged parts.


• Use high-quality parts: When you need to replace ignition system parts, be sure to use high-quality parts. Cheap, aftermarket parts may not be as durable as OEM parts and could fail prematurely.


• Avoid driving in harsh conditions: If you can, avoid driving in harsh conditions, such as extreme heat or cold. These conditions can put a strain on the ignition system and cause it to fail.
