05 LLY Help

Just bought a license and read calibration data from my room mates pcm. Made tire size changes and tried to program pcm with that changes. clicked get status and got the check mark. Clicked start, checked the warning and was expecting it to say license vin but before it got there it rolled up the power windows about an inch and then disconnected. Now the gauge cluster shows no fuel and the truck will not start. When re trying to read pcm or program it say status is unknown. Any help would be great.

Thank you.

Disconnect the batterys for about 30 mins and try to read the ecm again.

Thanks for the responce. I figured it out (disconnected the batteries) 2 mins after posting testerday but forgot to update the post. If this is like the other forums I guess this can now be closed.

Thank you!
