Okay so I just got a bunch of stuff done to my car... New JDM motor, clutch, timing belt, water pump, rack and pinon, master and slave cylinder, pressure plate. I got my car back yesterday and it felt amazing. This morning I was on my way to work and when I slowed down in the parking lot I started hearing this clicking noise and then a crack, suddenly my car turned off and it won't start again. Every time I go to start the car I just hear a loud click. The engine won't crank or anything. Can it be the Starter/Alternator? please help

 

I'm better either the JDM hand grenade seized, or it hydrolocked. Put a breaker bar on the crank pulley and see if you can turn it over by hand.
