Message Hi, It's great to join the club. To start everything off... I have a huge problem. I am not getting spark in one cylinder, I have changed coil pack,injector,ptu,plugs,and connectors but still no fire from just that one coil. I have tested all the coil wiring and it comes up the same voltage of 14.6V on every plug... every one including the one that doesn't work.
I can piggy back it off the coil next to it and it fires but runs bad of course because they are firing at the same time.

The center wire is the one that I piggy backed off so it must be something to do with the center wire. What does that wire do?

Does the ecu send a pulse to each coil? Or is there a chance it may be the ecu?

Could the CAS have something to do with this?

WHAT'S WRONG???
