trinity has shut down my 2003 yukon

[jeffmc412]

loaded the trinity in my 2001 Yukon 4 awhile. decided 2 unload it and loaded it n2 my 2003 Yukon. it shut the ecm down. sent it back and had everything reprogrammed. just got it back. installed ecm but truck wont start. created a back up of original tune and can load any tune I want but alarm has the truck so it wont get fuel. has code p1631 on scanner when I hook it up. tried clearing codes. tried all the turning key off and on and holding unlock button til my fingers are sore. i've googled everything I can find and tried everything with no luck. please help?!?!

a vats relearn should do it, post the backup file here and I'll disable VATS and see if that lets it start...

Thanks
