    Thanks for the log files. They show the ECM is not responding at all. Chances are the boot loader is still running in the ECM. Disconnect the battery for 30 seconds, reconnect and try reading the ECM again.


    Just for future reference: The LLY ECM has a built in boot block that is not erased during the flash process so it is ok to disconnect the power if a flash fails (even a full-flash), it won't kill the LLY ECM. The LB7 (and other older/other gas controllers) will most likely be rendered inoperable by removing power after a failed full-flash.

    Regards

    I just pulled the ECM out of the truck tonight, i tried disconnecting the batterys last night and it still didn't work, i talked with Monte at ATP and they said they should be able to get it working doing a bench tune.

    Still having problems with trying to get my truck to start, checked the fuses under the hood and don't have any power to the EDU fuse or the ECM fuse would this be caused because the ECM is not working or do i have other problems other the the ECM, "HELP"

    That would definitely cause the symptoms I saw in the log file.

    The ECM fuse supplies power to the ECM. If the EMC fuse is blown or not receiving power, then the ECM will not power up and will not function at all.
