Welcome to the forums.

How do you know there is no spark in plug 2 or 5 ?

You check the wires to ground. 1,2 and 4 should pulse when the engine is started. 3 should always be on.

You can't go by the colors.... go by the location.

If you aren't getting a +12v pulse on that wire when cranking or running the engine you either have a broken wire or dirty connector between the coil pack and the engine computer or the engine computer itself is defective.
