I got a 97 saturn sl1 my car got power but won't try to crank. It did it once for about 3 hours then worked fine for 2 days now it won't work at all.

Depends on what you mean that it has power. A battery can have enough power to do everything but start the car which takes the most power. Have you tried jumping the battery?
If jumping works, it is probably a battery problem. If jumping doesn't work, you may have a defective starter or starter solenoid. And always check that the cable connections to the battery are clean and tight. Good luck.
