Guys truck still doesn't run. I've logged everything possible. Nothing seems to be out of range. No dtc's no leaks. Truck starts and shuts off in 1 -2 seconds. Loosing my mind here. :banging: Still thinking it sucking air somewhere.
Mild build won't run.
- Thread starter SHOTZY
- Start date
heard of that before. i think it was a vats (security) issue. i think you need a tech2 but do not remember enough details to say for sure 
I have no Idea, I'm just throwing out ideas.. IDK what years they starting doing this, so dont try till we find out. Maybe keep the key in start position, because I know on my 2006 if you turn it to start with the engine running it will not engage the starter.
This may be able to tell if its in the ignition or not... Just a suggestion

Duh, sorry guys. Brain is fried. Scanned with tech 2 today. Nothing unusual. Should I try turning the vats off or can you do that? All grounds are good as far as I can tell.
my wifes 02 grad-am did the same thing and i reset the vats with my scaner i know it's not a dmax but still mite work
8 months. The wierd thing is that the truck has ran for about an hour or so. I drove it to put fuel in it and thats it. Woke up the next day and its back to the same crap. Only now can't get it to stay running.
its definitly the vats system. My buddy had the same issues with an 04.5 lly that sat at his trans shop for like 6-8 months

Or try shutting vats off in tune, or set the key off to like 10 seconds between reset and use link above. If you leave the vats stock in the tune, you need to follow the link close and it takes about 30 minutes.

Battery down that long will throw ECM long term memory fail and can do some funky things
