I finally got the SS back together from the re-build, now it wont turn over. I've got every wire connected, all grounds in place just wont't hit a lick. I have a diagnostic scan tool, (Auto X-ray), but it is not responding to the vehicle. All the gauges, radio, lights work fine, but when I try to crank it, everything turns off. Then a few moment s later it all comes back on. I've already replaced the ignition switch cylinder and ignition module hoping that might be it, but no such luck. My last 2 ideas are either the PCM or BCM.....Just seeing if there might be anything else before I have it towed to the "Stealership". Any help would be great!
