2002 Saturn L300 Ignition Control Module?

2002 Saturn L300 6 cyl Two Wheel Drive Automatic 77000 miles

This problem started a few weeks ago by not starting one time. I waited a few hours and it ran fine for a couple of weeks. My first gut was that it needed a new battery. Since the car started back up I didn't think much about it and kept driving it. Then it started dying when I was idling at a stop light or so. We had it diagnosed as a fuel problem but the injector looked okay - we replaced the fuel filter and put in a gas tank additive. This seemed to work for a couple of more days. Then it started dying again - one night it died for good and it was diagnosed as the ignition control module and a very dry battery. They didn't know how to work on a Saturn. We called the auto parts store and here is where our confusion begins - they had a left and right ignition control module. We tried another store and they stated that Sautrn doesn't have an ignition control module. What is the equivalent part name?
