Default SOS...06 cts-v not starting

having issues with my cts-v. Does not want to start or turn on radio or turn on dashboard, nothing. Headlights work. Doesnt want to lock/unlock with fob.
Here is what happened...
I was hooking up my nitrous switch plate, had everything connected and by mistake a wire touched the 12 V switch wire and the WOT signal wire on the ARM switch and then everything shut down. Cant get it to start after that. Tried to jump with with jjumper cables with no luck.

Damn it!!!! was getting the V ready for the 1/4 mile track this friday, hopefully we can get it started again by tomorrow.

thank you all

It really can only be either a fuse or a relay that popped when you accidentally tapped the wires. I can't remember which ones are located in the box under the rear seat beyond the fuel pump but I would make sure to check there as well as the box up front.

It will be under the hood, the rear fuses are for fuel pump and interior stuff

i just checked all the fuses and relays under the rear seat and under the hood and they are all ok.

the car now lucks and unlocks with the fob, it just doesnt light the panel lights when the key is put in the ignition and turned. radio still doesnt turn on, car still doesnt turn on, or crank at all.

Just a couple of ideas, based off anything i could think of that would prevent the car from turning over:

1. Fuses
2. Clutch sensor
3. Vehicle security (may have lost its link to your key which you can google the relearn procedure, or may be related to the dash lights not working)
4. Starter, or the wiring to the starter.

Sorry man, I'll post up if I think of anything else.

I checked all fuses and relays...
The ignition wire that i tapped into for the niteous switch playe was getting 12v before all this happened whith the ignition tirned to on, now i get 0 volts. I changed some relays around and still nothing. Could it be that the car thoughth that it was being stolen and shut itself competely off? How can i get it off of theft mode?

I ordered a new ignition switch to see if we get better luck with that. It was only $27. I should get it in the mail today. Will install and follow up with you all.

**** THE IGNITION CYLINDER!!!!! **** YOU IGNITION CYLINDER!!!!!

what a bitch to work with that cylinder, i went at it for a few hours with no luck on removing it. i unplugged the battery, pulled fuses in the back, and inserted an awl from underneath the steering column to release that cylinder and it only released it so much, but not enought to compeltely remove it. I then tried to make more room to work around it and was able to remove the ignition switch (electrical) and went to put everything back in, that focking cylinder did not wanted to go back in its place. So i took the switch out again, and some plastic little ***** in that area and still no luck, im frustated!!!!...Not enough room in the cylinder area, cramped the **** up in there and nowhere to go. I tried removing the airbag and steering wheel and dont know how to either. FML!!!!!!!!

Always,

Felipe

Hate to say it, but...dealer might be a better option. It's hard to know what got nuked. With a Tech II scanner, they might be able to pull a specific code.

IMO, taking the keyswitch apart was a no no.
I think you took out communication with the CPU(PMM) and according to the book, once ClassII communication is lost, if the PMM does not send a "wake up" command to the other modules, you are dead.
Did you probe any of the wires going to the keyswitch for 12 volts before you took it apart?

I did check for voltage on the switch and was getting 12v before i shorted the waires, it was not getting anything afterwards, so that is why i went to the switch.

I finally beat the **** out of the cylinder and it popped out...(I HATE YOU LOCK CYLINDER), with that happening, i need a new one. I called the dealer and they cant seem to find a lock cylinder for my V, let alone for a manual trans vehicle. I looked online and all the cylinders that are for sale are for auto transmissions only...where the hell can i source one out?

thanks

Here are some diagrams of the ignition and associated modules.
I believe you may have screwed up the communication with the DIM and or RIM modules.

If the security light isn't lit, I think you killed the communication.
