no spark cyl 2 and 3

[willnatale]

I have no spark In cyl 2 and 3. I changed the coil packs and the power transistor. Does anyone have and idea I read it might be the ecu but Idk how it would just break I shut it off to put anti freeze in and that was it no start?

Check the obvious first... Check wiring from coil packs, power transistor, and CAS. Could be a loose or stripped wire somewhere. Pull the ECU and take the cover off and check for any burn marks, bad smells, leaking capacitors, etc. If all of this fails you can try swapping the CAS (Cam angle sensor).

Does anyone one where I can find a diagram for the coil packs online? I might have switched something not known it
