Where is the coil pack on a car?
by Will Howard. A coil pack is a pack of ignition coil generally located in the top area under the hood, above the engine. Part of a car’s ignition system, it is typically box-shaped in appearance, and amplifies the voltage sent to individual spark plugs. There are several ways to determine if your car has a weak coil pack.

Can a bad spark plug cause an ignition coil to fail?
The ignition coils can fail due to faulty spark plugs – it is actually the most common problem and cause of ignition coil failure. Bad spark plugs can overload the ignition coils and overwork them. If you don’t solve the spark plug issue, the oils will fail again. How Much Does It Cost To Fix The Ignition Coil?
What happens if the ignition coil does not work?
If your ignition coil does not transmit enough energy to the spark plugs in your car, your vehicle will have to burn and use extra fuel. This is the only way that the vehicle can keep running – by burning the extra and residual fuel.
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.
When do you need to replace the resistance coil?

Why is my spark plug still not working?
Still no spark If the magnets are good, it’s gapped even reasonably close, the small ground wire from the base is disconnected, you’ve not got rust or corrosion between the coil and the mounting posts, and you’ve tried at least two new spark plugs (sometimes even new ones are bad), then you have another bad coil.
What should I do if my engine won’t start?
You should see a bright spark jumping the gap in the spark tester. If you don’t see a spark, repeat the test. This time, adjust the spark tester to 30KV. If you still don’t see a spark, repeat the test and set the tester to 10KV. If this time you see a spark or no spark, you have a problem with the ignition system.

How can I tell if my ignition coil is open?
Check the reading on the multimeter and compare it to the resistance specifications for both the primary and secondary windings. If the reading falls outside the normal resistance range, you’ll need to replace the ignition coil. A zero means the coil shorted internally. An excessively high reading means the coil is open.
Why is a coil pack better than a distributor?

When is an ignition coil needs to be replaced?
If the trouble code changes from P0302 to P0303 (cylinder 3 misfire), the ignition coil that was originally at the cylinder number 2 is bad. Ignition coils are also recommended to be replaced if they show cracks, traces of arcing or other damage that may cause it to short out.
How is the ignition coil pack in a car controlled?
This electronically-controlled pack consists of ignition coils that are controlled by the car’s main computer. The main function of the coil pack is increasing and building the energy needed, then releasing the voltage through the spark plug cables. When the energy reaches the spark plugs, it starts the combustion process.
How does the ICM work in a car?
The ICM functions in two modes. These are the Start and Run modes. When starting the engine, the ICM allows full battery voltage to the coil. This ensures there’s a hot enough spark to start a cold engine when the fuel mixture is rich, and the battery is dragged down from the starter.
