How is the coil pack on a Ford Mustang controlled?
How is the coil pack on a Ford Mustang controlled?
The coil pack is controlled by the PCM (powertrain control module) to deliver spark to the individual cylinders upon request. The coil pack eliminates the need for a traditional distributor and coil ignition system.
Can a bad coil pack cause a misfire?
There is more to your Mustang’s ignition system than just the coil packs. There’s also spark plugs and plug wires. There are also non ignition related circumstances that can cause a misfire. That would include lack of fuel pressure, bad fuel injectors, or even a timing chain (or belt) that has jumped.
What kind of ignition system does a Ford Mustang have?
This article applies to the V6 Ford Mustang (1994-2004). By the early 1990’s, the traditional ignition system consisting of an individual ignition coil coupled with a distributor was being phased out by Ford, and their new Mustangs were coming with a state-of-the-art electronic ignition system.
Do you need new spark plugs when replacing coil pack?
Yes! It is highly recommended that new spark plugs and spark plug wires are installed when replacing the ignition coil pack. This will ensure that the new coil pack is not being overly stressed by old plugs or wires that could potentially lead to premature coil failure.
How can you tell if your Mustang has a coil pack problem?
Using your test light or multimeter, test for voltage at the power pin of the electrical plug while a friend cranks the engine. If there is power at the plug, the coil pack is receiving power and the problem is likely within the coil pack instead of the PCM, fuses, relays, or crank position sensor.

Can a bad spark plug cause a bad coil pack?
A bad spark plug may be causing a rough running engine or engine misfire that is misinterpreted as a bad coil pack. Similarly, check that all spark plugs wires are fully seated on the spark plugs and coil towers, as a disconnected plug wire could be causing the engine misfire.
Is there a problem with my Ford Mustang V6?
A common problem on the 1994 to 2004 Mustang V6 models is that the ignition coil pack is prone to failure and can lead to rough running, poor idle, and an unsightly check engine light. Fortunately, a faulty coil pack can be quickly diagnosed and easily replaced.
