I just got an 06 auto to replace my 99. Ive had for one day and now truck wont start. It had a diablo programmer on it and i used it to check for codes.. I found a brake circuit a code and a p2509 pcm and ecm signal.

When i reset the codes the truck cranked and fired for about 30 seconds than shut its self off. Then i tried to put the truck back to stock but it couldnt find the file or some kind of error.

I hear the starter relay clicking, the batteries are supposdly new. A couple times all the lights on the dash started going off.

What the heck could this be?
Thanks!
 
Weak batteries will make dash lights flicker when you try to start it.
