I have a 2002 Chevy Malibu and when i turn the key in the on position all of the lights come on but when i try to start it up the car turn over but won't start in the lights dim out. What couldit be?

Check your fuses first but I think its the battery.

Thanks im going to take the battery to AutoZone

Its your battery. Don't buy an Autozone or walmart battery. THEY ARE JUNK! A/C Delco, Interstate, NAPA gold, heck even a Sears Die-Hard is better than Neverstart(Walmart) and Neverlast(Autozone). Spend a few bucks more and get a better battery.

My 2011 Malibu was doing the same thing. I found a list of reasons why online. I followed one suggestion of tapping on the driver side trunk ( where fuse box is) and it worked. I had the fuse box replaced twice now but no longer an issue. Cheap wiring I assume. The fuel pump fuse is in there and that’s the one that was all black. I don’t know anything about cars but I did find these forums helpful so before you go and replace the starter a bunch of times try that.
