Sorry I kind of lost this thread. First off I went to Tustin Hummer instead of Cerritos, and was a night and day experience. Super cool people, and great service. After we couldn't reproduce the problem, and found no codes, I told him that someone mentioned ignition position sensor or something. He pulled and replaced the whole ignition at the column no questions asked. So I haven't had a problem sense. He did also check fuel system delivery and all that, but said was an unlikely problem because it wouldn't even turn over. HE also checked starter relay and solenoid, and said it was a brand new starter just replaced 6 months ago at a different dealership.
Unlike the last Cerritos guy who told me my VIN # didn't fall into the "problem head" range which I knew to be false, Tustin confirmed I was in the problem range and I have not had a head replacement done yet. He checked compression and everything checked out fine. He also said he would work with me to get a discount on my extended warranty when I buy that because I fell within that range of problem VIN #.
Whatever happens from here, who knows, but at least I left there feeling good about Hummer. I am taking it back this week to get the AC vents fixed, flaps are broke, and 2 new tire sensors and a faulty valve stem (yeah he actually pulled the tires and checked the sensors). Good people though. Go there if youre local to So Cal, Tustin Hummer!
