Don't take it apart..
The easiest method (quick and dirty) is to:
* Remove the CAS from the timing cover* Remove the coil packs but keep them connected to the loom* Remove the spark plugs and insert in each coil pack* Rest the coil packs somewhere where you can see the spark from each plug* Plug the CAS in, turn the ignition to "on only"* Spin the CAS by hand and watch each coil pack for spark and listen for the injector click, they should happen very close to simultaneously* If either one doesnt happen through the cycle, there is possible issues with the CAS and you should try a different (new or otherwise) CAS to see if the issue is replicated in the same manner
Now this will not 100% point to the CAS being an issue as there are other variables that impact the operation of the CAS, but it will eliminate possibilities..
Hope this helps you
