Why they were busy? (Not OK)
==> When you make a question in English using the verb BE (is, was, are, were, etc), you need to invert (i.e. switch) the subject and the verb, like this,
They were busy because....
Why were they busy?
Why did they come? (OK)
When they came? (Not OK)
==> When you make a question in English using a verb other than BE, you need to add "DO" before the verb:
They come at 5:00 in the morning.
When do they come?
If the verb is present tense, then add "do"/"does",
He comes at 5:00 in the morning.
When does he come?
==> The "s" on "comes" is moved to the word "do", making "does".
If the verb is past tense, then add "did", like this,
They came at 5:00 in the morning.
When did they come?
==> "came" changes to "come".
