Dodge Journey 2014 won't start after overheating

We were driving normally when all of the sudden vapor started coming out from the engine. The car turned off by itself and I was able to park right away.

One "tee" plastic coupler that goes by the heater core had broken and caused the leak. After I replaced it, the car wouldn’t start again. I used up all the battery trying to start the car but no luck.

Any advice? Thank you.
