1999 Saturn Sport Coupe

U don't have the floor mat under the clutch pedal do u keeping it from closing the clutch switch sounds silly but have seen that happen more then once. Make sure the battery cables are clean and tight.U said ur battery good u had it tested?I would say u had a bad starter or clutch switch u can test switch by unpluging it and putting a jumper in instead of the switch just make sure the car is in neautral then see if it starts. If it doesn't then u will have to go to ur starter and test for power to the purple little wire while trying to start the car if u have power to that wire u have a bad starter. Let me know what u find.
