I have a saturn SL2 and i cant figure out what the problem is. I turn the key and nothing happens, the starter doesnt even try to turn. The lights and radio will go on fine. It has died on me once before when i tried to start it and i figured it was the battery, i jumped started it and it worked fine. So when it died this time i thought i needed a new battery. Ive replaced it but still nothing. Help please!

maybe a bad ground or bad starter

It started fine with a jump? I don't think thats your starter then. If I'm not mistaken, Autozone will do free starter checks for you. Do your cables look good around the post? Are they overly corroded or too loose?
