I have a 2013 boss. Out of no where switching out a tune my car won't start. Everything lights up on the dash like a Christmas tree. All the electronics work, but doesn't start. Doesn't even make a noise like its trying to start. Took the PCM to SCT but they say that the PCM is fine. What else could it be? Or could it be the PCM. By all the lights turning on I mean everything, abs,battery,brake,traction,another traction one,security,etc. Goes in ON position but doesn't even click. Checked all the fuzes and they are all working. Any clue?
