If you're going to give a smart-a$$ answer, at least be accurate. Most jet engines have a start switch which opens the start valve and introduces air into the engine to begin the N2
rotation (or N3 in the RB
-211). This same start switch also energizes the ignition. Then the fuel switch is moved on to introduce the fuel. On many engines, this action of introducing fuel also activates the ignition (the start switch only energizes the igniters).
Many modern jet aircraft are equipped with FADECs. In this case, the start sequence is all automatic, and controlled by the FADECs.
None of this applies to the CF34s on a CRJ, as I know nothing about that engine or aircraft. Unlike others, I will not presume to tell you what to do when I don't know myself.
