Cranks bit won't start 06 Elantra
 

Recently my engine shut off on me and coolant was on the engine bay. My thermostat was broken. Replaced the thermostat, thermostat housing, and radiator. Now my car only cranks but won't turn on. I'm confused on what could of happened. Everything was ok until my engine over heated and turn off on me. I need help

Sounds like the coolant got to some electrical parts
If you have compressed air then blow out the visible connectors
Then should check for the basics
Fuel, Air, Spark, Timing, Exhaust, Compression, etc. ....
That should lead you to what happened

Good luck
