gabysman - I think the ONLY problem is that you had a dead battery and you left the Edge plugged in during the recharging and restarting. I'm surprised the Edge shows anything if this is the case.

Try this: Unplug the Edge at the OBDII port, turn the ignition ON (but do not start the truck) then plug the Edge back in. It should initialize properly and you should be back in business. (Note: this is what 88Racing advised, and I think his advice was correct!)

DO NOT try to update the firmware in the Edge if the truck is holding a tune! This is a good way to make either the truck or the Edge inoperative.
