Car won't start! Help?

[05gtoautoX]

I have an 06 GTO M6, That I just installed pacesetter ceramic coated LTs and off-road mid-pipes, I took the car to my dads shop about 250 miles away to do this(he had a lift) and was told by a reputable tuner it would be fine to drive untuned after the install atleast this far(back home to get tuned), well all was good, it did have a CEL on but I expected that because of the lack of cats, I had driven maybe 200 miles and had to stop at a rest area for my daughter, turned the car off and it never started again, the headlights/tail lights come on, along with the dome and door lights, but none of the guage lights, message panel, seats don't move, trunk won't pop, horn don't work and doors won't lock, and if you try and lock the doors with the key F.O.B., the hazard lights come on and take about 2 minutes before they go off, all the fuses are good, battery is good, connections are good at battery and ECM, I've pulled the negative cable twice to try and "reset" it, hooked up my predator to it but says no trouble codes found, but I think it's due to the message panel having no power and NOT doing a system check. When you turn the key absolutely nothing happens, lights don't dim, no buzzers nothing. ANY HELP WOULD BE GREATLY APPRECIATED, Thanks.

I'd say DOUBLE check fuses. Do those GTOS have that pass key II like the fbodies? If so clean your key. I hope that works, I don't know what else to tell you.

any chance a wire might've got fried by the headers?

[05gtoautoX]

I've double checked ALL the fuses and I don't think any wires were touching the headers, I looked preety good too, I took it to the dealership today they'll get it in tomorrow we'll see what they say, I'll keep you updated. Thanks

it was the ignition switch, shorted out and blew the fuse, it's all good now, runs like a champ.
