did you try to prime it to get it to fire? get a schematic and look for the ground to the cpu. Should be constant power switching ground system, Look for what has the same gound or fuse and see if that is working. is your spark good enough to jump from the boot to block? I have found even able to jump a plug not good enough to ignite. Using known good parts is a good start before buying a new cpu if you can't figure something out.
