Yeah, I know. I don't even get that initial prime sequence with key-on.
I have secured a GM Tech 2 scanner for the weekend so I am going to start digging into the pcm and see if I can figure something out. With this tropical storm/hurricane making all sorts of noise and mess outside it'll be a good weekend to spend some time in the garage.
Thanks for the input.
