I have no spark on any of the four plugs. I have tried moving the bottom cdm to the top because the best I remember reading somewhere it starts with the fire at the bottom which is then tranfered to the top cylinder. Anyhow, I have moved the cdm's around to see if one of them was bad and still not spark on none of the four cylinders. What next? Am I looking at a bad stator? Also, could the ignition switch be a cause of no fire? I have multimeter and was curious of what to look for or any test to be done. Any information would be great.

Do you have the manual for the test values? If not, post your engine s/n as should have the manual for your engine and can forward it to you if you PM me with an email address.

Disconnect one cdm at a time while checking spark on the other three.

A bad cdm can cancel spark on all the others. Once you have spark on three replace that one that is disconnected.

Worth getting the CDI Troubleshooting manual. Stop circuit problem ?
