Question: where is the intake air temp sensor for 2.2L ?
 Answer: The Intake Air Temperature Sensor (IAT) is located in the intake air runner between the air filter and the throttle. It is not viewable in the picture above though.

Where is the cooling fan sensor?
 The coolant temperature sensor is located on the drivers side of the engine, down in the back.

I have a 2006 chevy Cobalt cranks over have fuel and spark but still won't start any help out there.
 As long as the fuel pressure is correct, then you either have no fuel injector pulse signal or the timing chains has jumped.
