    Need Help! Truck Not Starting

    Hey all, just drove the truck yesterday and today it won't start.

    Hooked a battery charger up to it to see if it was that, and still no juice.

    DTC's from my MM3 is showing "P2509:ECM/PCM Power Input Signal Intermittent".

    Anyone have this problem?

    Double R Diesel Tunes were installed about a year ago.

    Unhook everything and rehook it up.

    Make sure everything is connected.

    Sounds like it came unplugged somewhere.

    I would recommend you have both batteries load tested.
