Okay well i drove it to my cousin's apartment complex yesterday and when i was getting ready to leave it wouldnt start or crank at all. The battery is fine, its perfectly good. Whats weird is when i turned the car off and took the keys out, the radio still went, usually it shuts off right when i take the keys out. I checked the Fuses and they were all fine. PLEASE HELP! Headlights, instrument panel, and radio work perfectly.
