A break down of a Saturn ignition system. The CPS sends a pulsed reference signal to the DIS module which in turn also sends it to the PCM. The PCM uses this reference signal to tell the coil packs when to fire the plugs. Provided the CPS and coilpacks are sound, the problem MUST lie with the DIS module, PCM or the POWER SUPPLIES or wiring going to or from them. No offence, but you are throwing parts at the car instead of doing a complete diagnostic. MAKE SURE that the DIS module and PCM have POWER going to them. That being the case, CONFIRM that the wires running from the DIS module to the PCM are unbroken and suppling siganals to/from the two. Take the time to trouble shoot the ignition completely and correctly and the problem will show itself, the system is just not all that complicated.
