In this article we’ll explore the key components of a standard Ignition system and some of the reasons things stop working. A vehicle’s ignition system is responsible for activating the reactions in an internal combustion engine or more simply put, it turns the car on. This is accomplished by a series of parts known as ignition components that work with one another. These components vary by the type of ignition system inside the vehicle.

Most cars, trucks, and SUVs will have one of three types of ignition system. Either Distributor-based, Distributor-less, or Coil-on-plug.

Battery and coil ignition systems rely on mechanical parts to pass a high current through a coil which then causes the ignition. Electronic ignition systems use a similar method, except there are no mechanical components in use and instead rely on sensors to activate the coil.

Despite the differences, the following components are usually evident in both systems:

• Coil
• Spark plugs
• Spark plug wires
• Ignition module
• Distributor rotor

When one or more of the components is faulty, or begins to fail, the car’s entire ignition system is affected. These effects look different and will depend on the component that has failed. There are signs you can look for that can point to one or more component failures in your vehicle’s ignition system.

IGNITION LOCK CYLINDER

The ignition lock cylinder is the first component of an ignition system that is activated since it does so when your key is inserted and turned. Signs of a failed ignition lock cylinder include failure to start the car and trouble using your car keys. You may even experience some grinding when turning the key or the key not turning.

BAD IGNITION COIL

A coil takes the battery voltage and amplifies it to a voltage that is high enough to jump a gap. A coil that has gone bad will not be able to convert energy from your car’s battery into the voltage it needs to ignite the engine. A spark plug not receiving enough voltage could be a sign of a faulty coil, along with engine misfiring, difficulty accelerating, and poorer fuel performance than usual can also mean the coil has gone bad.

FAILING DISTRIBUTOR ROTOR AND CAP

The distributor rotor and accompanying cap orders the voltage to go to the right spark plug in the right order. The ordering of the voltage is a metal-on-metal connection and does wear over time. When this part fails it makes the car impossible to start or causes the engine to misfire. Drivers may also notice strange noises coming from under the hood, since parts of the engine will not get enough voltage to continue the chain of ignition.

SPARK PLUGS

Spark plugs do just what their name implies, they ignite a spark that then creates the reaction inside your engine. Spark plugs that are dirty will cause misfiring, low gas mileage, and shaky idling. Broken or damaged plugs will lead to hard engine starts and poor acceleration, so drivers should never let their vehicle pass the 30,000 mile mark without giving them a look.

See Something, Do Something

With three convenient locations in Georgia - Kennesaw, Woodstock, and Roswell, and servicing areas including Powder Springs, Acworth, Mountain Park, Crabapple, and Towne Lake, our shop emphasizes the importance of regular inspections of your vehicle's ignition system. It's advisable to visually inspect this system annually, and if you notice any issues, don't delay in getting them checked. The engine's reliance on the ignition system means ignoring early signs can lead to more severe and costly repairs later.

For example, replacing an ignition coil may cost between $300-$500, significantly less than the expense of replacing an entire engine. By paying attention to your vehicle's performance and ensuring annual inspections, you can often identify and address major issues while they are still manageable.
