I have a 2003 Saturn vue It was running fine and we went in Wal-Mart came out and it won't start. It won't crank over or anything when I turn the key but the lights come on I don't know whats wrong
Lights can come on , but battery might be not be strong enough to start the car. Call AAA or roadside assistance for help. But since your at a walmart, go in and purchase a multimeter and check the voltage. Is it 12.3 or better? If it's around 12V and battery is 5 years old, time for a new one. Go back into the store and get a battery and a wrench and perform the swap.
