When trying to start and lights go out, this usually means a power issue - battery, battery cables and their connections. Unless you're familiar with car batteries, bring it to your favorite auto store selling car batteries for testing. Tests go one of several ways; dead, partially discharged and needing a charge or good. Your descriptions are either a dead battery or poor battery cable connections. You can always try a boost from another car battery or portable battery booster but you must ensure your car battery cables are clean and free of corrosion.

When using a boost from another battery, the red cable jumper always connects to each battery red terminal post. Some Saturns have a second red terminal next to the engine fuse box with a cover, flipped up to reveal a red post for a jumper cable connection instead of the battery side terminal. Ground is connected to the engine block, any bare metal bolted to the engine or large bolt for the alligator clip to grab onto. The larger surface area allows more current to help boost a dead battery/startup. Once started, if the drive belt and alternator are working, the alternator takes over - supplying all the electrical needs of a vehicle while slowly recharging the dead battery.
