How big is the coil pack on a Ford Focus?

Official ford specs are for 1.6 engine is 1.2mm the 1.8 engine is 1.3mm Just updating here. myself and a friend dug deeper today. We removed the coil packs and tested each one produced a spark on a new plug. They all did. Then we tried all the old plugs, they all sparked.

Can a plug gap cause a coil pack to break?

Bear in mind that plug gaps have an effect on coil packs. There have been a number of threads on here in which it has been stated that the specified 1.3mm gap generates voltages high enough to cause the coil packs to break down. I think this was referring to the 1.6 engines with wasted-spark systems.

Where does the voltage from the coil pack go?

When the electronic control module (the car computer) sends the signal to the ignition control, the voltage is released from the coil pack through the spark plug cables to the spark plug.

When is the distributor replaced by the coil pack?

When the energy reaches the spark plugs, it starts the combustion process. In more modern cars today, the distributor is replaced by the coil pack. This is typically because the coil pack is more reliable and consistent than the distributor.

Can a bad coil pack cause a Ford Focus to stop running?

Bad Coil Packs are one of the more problematic ignition issues that can occur with the Ford Focus. A bad oil pack can make your Focus almost un-drivable. Or it may have little effect at all on the engine’s ability to run. It’ll get worse as they lose their ability to fire the spark plugs.

What are the symptoms of a faulty coil pack?

The usual signs of a faulty coil pack are: The ignition coils are reliable but they can fail for various reasons such as vibration and extreme heat. However, voltage overload caused by plug wires or bad spark plugs is the most common reason for their failure.

When the electronic control module (the car computer) sends the signal to the ignition control, the voltage is released from the coil pack through the spark plug cables to the spark plug.

Can a bad coil pack cause a spark plug to fire?

Coil Packs take the place of the distributor and coil in older vehicles. They receive instruction from the engine’s computer on when to fire the spark plugs. The symptoms of bad coil packs are almost the same as bad spark plugs.
