I Had My iphone 3 Charging in My Car Turn The Car Off Phone Went Black

Welcome to iMore! Is the phone not powering back on at all at this point? It could just be frozen up. Try to reset your device by holding the power button and home button down simultaneously until you see the Apple boot logo.
It may just be time for a new phone. Your 3G is almost 8 years old at this point and it's battery is most likely way past its operating life.
