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.
How do you test the coils on an eclipse?
The way in which you test these coils varies depending on the type of ignition system and the size of the engine. Secure the Eclipse by putting the gear shift in “Park” and applying the emergency brake. Perform the cylinder drop test with the engine idling. Remove a spark plug with insulated pliers for a few seconds.
Can a car not start with a faulty coil pack?
The coil pack within your car is an important piece of the ignition system. Without the coil pack properly functioning, the ignition system won’t work, and your car won’t start. Although numerous parts of your car are imperative and must work together in order to function at an optimal level, the coil pack may be one of …
What makes up the bigger ignition coil pack?
As we said, the ignition coils make up the bigger coil pack. An ignition coil is an induction coil in a car’s ignition system. An induction coil is a spark coil that produces a high voltage from a low voltage supply.
Why does the ignition coil keep burning down?
I didn’t check #1 and #3 because intake is still in place. Fluctuating voltages are good, but signal voltage is 0.4 at high signal, so each one is continuously firing the coil pack and melting them down. I also checked the ECU to make sure it had proper voltage, It had 12V on cable at pins 119, 120 and 7v at pin 109.
Why is the oil leaking from my ignition coil?
The first is simply due to age: if it’s traditional “wet” coil filled with transformer oil, then the oil can either leak out or simply break down with age. If so, the fix is simply to replace it and there are often modern compatible dry resin coils which do away with the oil filling completely.
What causes a dry resin coil to fail?
Dry resin coils can also fail with age or hard use, but it’s far less common than with wet coils. A failing coil which usually works perfectly well be over-stressed if the vehicle is left idling for long periods on a hot day, such as during summer traffic jams.
What happens if the ECM fails on a car?
The fuel and ignition systems, as well as several other engine management functions, of many vehicles are controlled by the ECM. If the ECM or it’s relay fail, the entire engine management system will be left without power and will not function as a result.

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.
Is there a way to test a coil pack?
You can test coil packs using an OBD II diagnostic scanning tool, or code scanner. It can read error codes with the vehicle’s computer, and can diagnose the functionality of the coil pack. All cars built since January 1996 have OBD-II systems.
How many volts does a coil pack have?
How a Coil Pack Works. When creating a spark at the spark plug, the fire must initiate from a high voltage supply, so as much fuel as possible burns in the cylinder. Whenever the combustion process is started, the coil pack builds up the energy, as much as 50,000 to 75,000 Volts.
