Default No power to coilpack

Been trying to figure out why Im not getting any spark after I had 30 volts go thru my system. Ive replaced the coilpack, plugs, and plug wires. I've double checked that Im getting power to my CAS, but haven't check the CAS itself, although its fairly new. I've also checked and replaced all the main fuses.

I checked to see if theres any voltage coming out of the wires that go to the coilpack.... nothing, not even when I crank it over. What all could stop the current from flowing thru those wires, a short?

Engine turns over fine and it ran fine before the 30 volt overcharge. Mind you I had it running on a MSPnP, but it was fired and now Im using my stock 97 ECU.


Im slowly tracking this down, I'd just like some help

Hate to throw out the obvious, but have you checked all the main fuses and such already?

Primary power to the coilpack comes in on the blue wire. It does not pass through the main relay, it comes through the 80A Main fuse, then the key switch (IG1 position) and that's it.

If you're getting power on that line, but not getting signal coming in on the brown and brown/yellow wires, that's a whole different ballgame.
