Yo, my brother gave me his 2500 a few months ago (Happy Birthday to Me ! ) and she's been doing fine until yesterday. Got towed from the loading dock to the mechanic. Symptoms: crank, 1/2 fire, stumble, stop she's got fuel pressure.....Found the key re-set method on-the line and told mechanic but he said they did that and it's something more. Being sent to another shop for diagnostics......Any clues ? Thanks !
