    Do you have a way to read the codes?

    Take it to a parts and use their code reader if you don't want to buy one.

    Most places don't charge to let you use them in the parking lot.

    Do you know how to drain your water separator?

    It's a yellow valve under your fuel filter on the drivers side of engine block.

    Open that valve and it'll drain any water the system has pulled out of your fuel.

    Close the valve, key on and off your ignition 4 or 5 times to prime the fuel system and you should be good to go if that's your issue.

    This needs to be a part of your maintenance because common rail injectors hate water and trash plus common rail injectors are very expensive.

    Let us know what you find out.
