CS83 is the Borg Warner part number off my 92's ignition control module. Never used it either, I replaced all the fuses, relays, starter, battery, cables, etc, etc, etc.

I noticed that when I jiggled the PDC it would start, then not. When it doesn't start I rake the box towards the passenger side turn the key and it fires. Guess I should figure out the problem...but now I know how to start it.

what is the PDC?
what box do you shake?

Power Distribution Center. Guess maybe your on the right track, CPS seems to be a common theme. You might try unplugging and re plugging the connector first as it also is known to cause trouble.

do check for codes key on key off

Replacing the crank sensor may do the trick.

A failing crank sensor is the #1 cause of no spark on the Jeep 4.0 engine.

Let us know if this resolves it.

PDC is the main fuse/relay box under the hood
