Well, just as I figured...finally get the chance to play with EFI Live on my LLY, and something goes horribly wrong!!!

All I was trying to do was read and back up my stock file for my 2005 LLY and now I can't get the truck to start.

When I first tried reading the ECM, it said something about the ECM being locked, and I tried it again, but it hung up at 4kb of 1200kb and would not go any further. I hit the "stop" button and tried it a couple more times, and now it won't even connect to the ECM. I'm getting a "EFI Live cannot communicate with the PCM, Disconnect the Scantool if connected, Please turn off the ignition, blah blah blah" message.

HELP, how do I get my truck to run again??????
