When you start your car, the engine turns over and starts. This process is called cranking the engine. The car’s ignition coil helps to do this by sending an electric current through a wire coil. The current causes a spark in the wire coil and sets off the engine.
How an Ignition Coil Works
When your car starts, the spark from the key turn starts a small fire in the coil. This small fire gets bigger and bigger as the coil supplies more and more electricity to the spark plugs. The heat from this big fire melts the metal on the plugs and sends a spark racing down the plug wire. This spark turns the engine over.
The Parts of an Ignition Coil
In this blog post, we will be discussing the parts of an ignition coil and their function.
An ignition coil is a small device located in your car’s engine that helps start your car by providing a spark to ignite the fuel in the engine. It consists of several metal windings wrapped around an iron core, and it needs to be properly maintained in order to work properly. The following are some of the main parts of an ignition coil:
1. Coils (or wire strands) – These are the actual coils that create the sparks when you turn the key in your car.
2. Core – The core is where all of the metal windings are wound around. It’s also where the spark is generated.
3. Plugs – The plugs are what connect the coil to your car’s electrical system. They’re usually made out of nickel-plated steel and must be replaced every time your car has its coil replaced.
4. Wires – The wires come out of the plugs and go into your car’s electrical system. They help to supply power to the coil and also keep it isolated from other electrical components in your car.

Diagnosing and Repairing a Car Ignition Coil
If your car won’t start, you may suspect the ignition coil. This small, but important part of your car’s electrical system helps bring the engine to life. In this article, we’ll explain what an ignition coil is and how it works. We’ll also give some tips for diagnosing and repairing one if necessary.
What is an ignition coil?
An ignition coil is a small device located inside the distributor cap of your car’s engine. It’s responsible for igniting the air/fuel mixture in the cylinders when you turn the key to start the engine.
How does an ignition coil work?
When you turn the key to start your car, electricity passes through the ignition coil. This electric current causes a spark in the air/fuel mixture inside the cylinders, which starts the engine. If your ignition coil isn’t working properly, you may not be able to start your car.Symptoms of an ignition coil failure may include:
-Your car won’t start regardless of how long you wait
-The engine dies after only a few seconds of cranking
-The car has a difficult time starting in cold weather
-The engine seems to lose power after being started for
How to Change the Car Ignition Coil in a Ford Focus
Changing the car ignition coil in a Ford Focus is an easy job that can be done by any car enthusiast. Here are the steps:
1. Open the hood of your car and locate the brown wire connected to the battery. This wire will be attached to the coil pack.
2. Disconnect the brown wire from the coil pack and gently pull it away from the rest of the system.
3. Remove the six screws that hold down the coil cover and remove it from your car.
4. Locate and remove the old ignition coilpack. It should look like a small black box with several wires coming out of it.
5. Install the new ignition coilpack in the same way as you removed the old one, making sure to reconnect all of the wires correctly. Replace the cover and screws and you’re done!
