    I take it truck will not start...

    leave battery connected;

    pull PCM/ECM fuse for 1 minute and then reinstall;

    see if truck starts now.

    The pcm has been erased, but in the middle it looks like another module tried to talk and reset itself and the other modules during that process.

    You need to pull the fuses for your aftermarket radio and try it again. that is if you have an aftermarket radio.
