Whether your Ford or Mercury car or truck CRANKS but DOES NOT START or runs with a MISFIRE Condition, this article is for you. With the tests I'm gonna' show you, you'll be able to pinpoint the problem to the ignition control module or the ignition coil or the Profile Ignition Pickup Sensor (PIP Sensor) or the spark plug wires or the Distributor Cap. This article applies to both the Gray colored Ignition Control Module and the Black colored Ignition Control Module. The Gray colored Ignition Control Module is called the Push Start Module and the Black colored Ignition Control Module is called the Computer Controlled Dwell Module. These Ignition Control Modules (ICM) are not interchangeable but are tested in the exact same way. Also, the photos (in the image viewer) show some of the tests performed on a V8 engine. This might make you think that they don’t apply to your 3.0L, 3.8L V6. Well nothing could be further from the truth. All of these test steps apply to both the V8, V6 and L6 Ford engines. As you can see from the image of the Ignition Control Module (in the image viewer on the left), the tests apply to the fender mounted Ford Ignition Control Module.
