Possibly, I like to replace those together at the same time, and even replace the ECM relay when I have replaced the module and pickup.

Ok I don't understand what are you replacing together, and what is a ECM relay, and where is that relay located?

The ICM and the PIP coil inside the distributor. The relay is in a little long narrow black box on the drivers side attached to the fender, it should be marked on the top of the box.
