I can get the first engine to start but the second one does not start surg the E and A buttons? Am I doing something wrong?

I'm watching Ikrananka's tutorial videos for the original game right now to re-learn the game. In video #3, he says that the engines are selected individually as Q (1), W (2), E (3), and R (4) and then A to start. This is the "automatic" start method.

While I own Redux, I haven't done anything with it, yet - maybe it works the same?
