C# yield problem

I'm having trouble adding a wait in c#. This is my setup.

//This method is calld by Update()
private void introPart() {

        if(!preTOff) {

            //Wait
            preTakeOff();

            preTOff = true;

        }

    }

//I then have the following method for the wait
public IEnumerator preTakeOff() {

        print("before");

        //Play particle flame
        //Play particle smoke

        yield return new WaitForSeconds(2);

        print("after");

        introState = IntroState.End;

    }

It just seems to pause forever and doesn't print either "before" or "after"? The method works fine when I make it a normal method so its being called.

Any thoughts?

Have I got the setup right? All I'm trying to do is make the script wait for 2 seconds before it starts the next part of the intro.

You need to call StartCoroutine to call it:

private void introPart() {
    if(!preTOff) {
        //Wait
        StartCoroutine(preTakeOff());
        preTOff = true;
    }
}
