Never heard of this method in a GM vehicle. I know of the 10-10-10 passlock relearn,.. which is all security but,... not any reset that you turn the ignition on for an hour and resets. You could easily reset the PCM by putting the negative and positive terminals together for twenty seconds...obviously removed from the battery. That will reset all modules.
he said it only takes 30 but I say an hour just to be safe.

If someone needs it, PM me and I'll post it up tomorrow.

I hate how a guy has a problem with his car, turns out to be the same issue you are having then they fix it and don't say what they did to fix it or what the issue was.

Best place to start is to pull your codes off of the DIC and then go from there. Also good to know if you have an auto or six speed as some of the no start problems are a little different based on the transmission.
Also good to know if it's a cranking issue (i.e. no crank) or cranks over with no start.
If you started a threat you may want to point us over there.
