What could cause a no fuel condition after a fuel line repair?

What is your question?

I recently replaced the fuel pump in my 2014 Nissan Versa S. I apparently didn't fully secure the fuel line connector. It came loose and the car cut off. I reconnected the fuel line to the pump properly. The car still doesn't start. Is there some sort of safety mechanism that may have been tripped because of the fuel leak. I have verified the fuel pump fuse is good.
