Re: 2004 H2 Won't start
this happened to me. if the battery goes dead, your alarm will set and will not let the vehicle turn over. It's like a safety feature. I called onstar from my cell and they can reset the vehicle once your battery is juiced up

yes it is a Compustar with auto start. My alarm guy unplugged the wiring harness from the alarm brain while the vehicle was down and it would still not start. He said that this procedure would take the alarm out of the list of possible problems.

Re: 2004 H2 Won't start
Peter, did you take it to the dealer and have them run the diagnostics? The whole dead truck thing happened to my Pewter 2003 H2 and the dealer ended up fixing it...somethng to do with the battery. This never happened to any of our other 3 Hummers so I assume it's not a common problem.
