hi guys im new at this forums stuff but anyway, i have a 04 powerstroke 6.0 and have ran a sct sf3 tuner on it for about a week now, and love it but every once in awhile you have to download new settings on it off your computer and so before i di i returned the truck to stock and i took the tuner to the computer and i fiddled with it and forgot about it. well i went out to my truck to go to the gasstation and my truck wont start it wont even crank when i turn the key over. some how i have locked my ecm up and dont know how to get it back? and i must have unplugged the tuner from downloading new tunes later on that day cause now the tuner screen stays blue and is stuck? i need help sct is closed till tuesday and ive gotta head to work.
