Car kills and won't restart for a few minutes. the Crankshaft sensor has been fixed. This all happened after I replaced the battery. The last idea I have is could it be a security reset issue or computer reset issue?

Help! I need the car!

 

Dealership is saying computer relay. I will know later this day.
