I'm having problems with #1 & #5 cylinders not firing. I have checked the coil pack,tested the wires going to the coil. Pretty much tested everything that I got off another site. Everything is good, but still can't get the cylinders to fire.

Is the compression good?

Yes there is compression. The #1 & #5 have a real faintspark but not enough to send a spark to the plugs. I've done all the test that I could find to troubleshoot the problem. I have singled out the coil, the plug and the pcm. So now I'm at a lost on what to check for next.
 






The plug wires...
