prob the ignitor...

my car had 12v on the coils and they never pulsed.. turns out it was a bad ignitor

Yup, most likely a bad igniter. You can hook up a 'test light' to the CAS and see if it flashes, but first replace the igniter with a known good one, or see if yours works in a friend's car.

UMM i think that the CAS sends the signal to the ecm which tells the ignitor to fire ?? Are you sure that the CAS is good ?? Or that one of the wires isn't cut/hooked up wrong ??

No cheap CAS's. Sorry ~ you can try and find one used, or from an importer... otherwise it's $tealer$hip.
