I think I have the dreaded ignition switch problem. Starts, dies, ABS light, engine light. May start later. May not. Towed it in. I have told the dealer 4 times that about 12 of you guys have had similar symptoms and the problem was the ignition swith. However, they said their diagnostic computer said it was a drive train relay. Ha! that only lasted one day and I had it towed in again. Now they want to replace the ENTIRE FUSE BOX, a five day wait for me.
How do you get these expert technicians to listen? Are there any TSB's that might address the ignition switch problem?

Had the same thing happen to me on the way to the Dragon's Tale run in Maggie Valley. I limped it over to the chevy dealer in Gainesville, GA. The mechanic there was having a problem finding out what was wrong. He finally found it after letting the truck run for a while, then shut it of, and re-started it, or rather tried to. When it wouldn't start the code reader finally sent the code that told him what it was. After replacing the ignition switch I haven't had a problem. Strange how you can let the truck sit for a minute or two, after it shuts down, then re-start it. The mechanic told me that GM had this same problem with earlier models of the Trailblazer, the only solution was the replacement of the switch. Maybe your dealer should check the TSB's on that truck for the ignition problem. Good luck.

WELL, YOU CAN TUNE THE PCM...HAVE SOME GREAT PERFORMANCE...AND DISABLE THE VATS AT THE SAME TIME....
THINK ABOUT IT...WHAT GOOD IS VATS? Like who is gonna try to steal your car with a copy of your key with no chip in it??????? Does anyone even sell keys with no chip.....???? It's sooooooo unlikely.........Shut it OFF.
Pretty good chance that turning off the VATS will do it....Recently, I had a late Camaro SS come in for tuning.....Occasionally it would not start...Customer said another mechanic told him it was a bad IGNITION switch....While tuning, I shut off the VATS and now the car is fine....Starts every time.
