symtoms came out of nowhere driving thru town. check engine light comes on and truck has hardly enough power to get to work. this 06 has 5k on it. i do have the juice attitude and the trouble code read #3 enjector circuit. called edge and they wanted the box and harness sent back to them. i set all harnesses back to stock and disconnected the batteries for an hour to reset computer and when i fired it back up it does the same thing. what does it sound like to you guys

 

It sounds like an injector control error. These can occur from rushing the starting sequence or from a failing sensor, or from the Juice. Since 04.5 disconnecting the batteries and killing the power does not fully reset the error trap, it will only remove a few codes.

Generally speaking, you most likely have a failed injector solenoid that is allowing the rail to depressurize by holding an injector open, so you have no power.
