It takes information from a device inside the distributor, the PIP (Profile Ignition Pickup) sensor and the PCM (Powertrain Control Module, AKA the Computer) to be able tell the Ignition Coil when to fire.
This PIP sensor has a bigger chance of being your problem than the ICM Module (TFI). After they moved the ICM (TFI) from the distributor to the fender they do not have many problems with it any more.
The ICM.
The PIP Sensor is inside of device below and this device, the Stator is inside the distributor.
Location of the ICM (TFI).

But you still have take out the distributor to press off the gear and take the shaft out.
