Trying to chase down a no-run condition w/code 14 and I figured out that cyls #1 and 6 (1st coil pack) are not getting spark. I've checked continuity in the coil pack harness and between the igniter and coils and all checks out ok. I've tried my spare ECU and also tried swapping coils and a known good pack doesn't work plugged into that location.
After studying the circuit I'm thinking it has to be a bad channel on the igniter since I'm getting spark on every cylinder but 1&6 unless I'm not understanding the TCCS Tech Doc and how it uses the IGdA and IGdB from the ECU to determine when to fire the cylinders and it's not getting the signals it needs which would possibly a wiring or CPS issue.
Thoughts? Any help would be greatly appreciated, was hoping to take advantage of some of the cooler weather we're having down here...
