Hey folks! Thanks in advance for any help on this starting issue. My 04 3500 is having a difficult time starting after it has been running/heated up. It only happens after the engine has been running for a good 30min or more. I park, turn the key and it cranks like its going to turn but does not. If I put it in Reverse or Neutral (after it decides not to start) it will fire right up. Sometimes after 2-3 tries. Any advice on what might be causing this issue or how to remedy it?
