My car will not start after I ran out of gas, but I put some in. Usually it cranks up, but this time it did not. What could be wrong with it?

You should never run your gas tank that low.

In tank fuel pumps are cooled and lubricated by the fuel in the tank. When you run a car out of gas or very low, it pumps a lot of air through the pump which overheats it and causes some severe wear and many times, failure when they cool off.
You will need to use a fuel pressure gauge to verify this.
