Not too familiar with 2.4L, I have a 3.0L and, not surprisingly, the engines look vastly different. If the engine is cranking, but not starting you can try to spray some starting fluid into the air intake while someone cranks the car. If the car starts briefly, then you might have a bad fuel pump and that needs to be replaced. Not sure what that cable belongs to, but it looks like it connects to something with four prongs so it's probably important. Possibly an O2 sensor.
