View Full Version : 04 3500 strange starting issue

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?

it might be a worn cam position sensor near the back cylinder5, or lose wiring connection to it.
it may be a dirty or worn fuel injector,
it may be a bad crank position sensor or lose wiring connection to it

Forgot to mention that I had this issue when I first got the vehicle 4 months ago. I changed the fuel filter and the problem disappeared. It's only been three months since the fuel filter replacement so I don't think it is the fuel filter itself. Will have my mechanic check the 3 items you mentioned. Thank you!
