Answer
Hi Joni,

If it didn't start right after the accident I would say it was the inersia switch located in the trunk of all newer Ford products. But because it restarted, it is likely the battery. An easy test for a bad battery is this: Jump the car and get it running. While it is running disconnect the positive (red or plus sign) side of the battery. If the car dies, it's tha alternator. If it continues to run, it's the battery. Let me know how that goes! Thank you, hope I was a help.
