Check my logic

J-spec S5 TII-

I cant get any spark. I have power to the coils, so I am assuming that the ECU is not giving the signal to fire.
-Reasons why:
1.Crank angle sensor not wired correctly?
2. Knock sensor incorrectly wired?( I have it wired to a black/yellow wire, but along with it, there is a black/white with red dotted wire that isnt going to anything. Any ideas on whether that may be an issue?)
3. The leading coil not connected to a condenser?(that little black connector with round inlet. There is one on the trailing plug also)
4. Any other ideas?


I've tried checking my CAS wires by checking continuity to see if it goes to the correct ECU pin, but never got a noise. Is there a short or are the wires going somewhere else?

I am trying to remember what the two wires were that you need to switch when using the NA harness.

Could anyone check my logic on this? Any other help would be greatly appreciated!
