What is am ignition module
I think your question is : What is an ignition module? An ignition module is an electronic unit that takes the place of the old points and condenser that ran cars for years. They have gotten smaller through the years. Most of them are now either mounted inside, or just outside of the distributor, most of the newer vehicles it is part of the ECM.
Seen your other post. The ignition control module on the 2.8 v-6 is attached to the coil pack "rack". It is mounted under the coil packs. The coil assembly is on the front of the motor below the exhaust manifold. I have/had many of these motors and have never had a ICM failure, but it could happen. The GM TBI motors are bad. What does the motor do or sound like when it dies.
It misses like a sob
I connected a wire to 2 towers on the 3n 6 coil to get voltage to dead tower
