I changed the tune on my 6.0 this morning and it will not start now. I've tried to reload the Stock tune as well as several others and the ITSX keeps having issues with identifying the ECU. When it gets to the point were i turn the key on it just sits there like it does not see the key on.

Any ideas?

 

Sounds like you are gonna have to have your PCM reflashed at the dealer.

 

PATS key???

 

Tried the ignition trick several times with no luck. The THEFT light just starts blinking fast after I turn it on after the 10-30 second wait

 

I'm not familiar with how tuners work, but as a Ford tech, I do know that any Ford vehicle requiring a PCM replacement requires a PATS reset for the new PCM to "shake hands" with both PATS keys. A PCM REFLASH however, doesn't.

 

Disconnect both batteries and turn the headlight switch on and leave it for 15-30 minutes.

Reconnect batteries and everything should be fine.

Call SCT tech support. They can walk you through how to get it back running. You're not the first.
