My diesel truck will not warm start. Only cold start.
What is your question?
If I go to the store I cannot shut my 2008 dodge ram 3500 6.7 diesel truck off or I cannot restart it. 4 hours later after it cools off it will start again. I get error codes P0471 (I replaced the Exhaust Pres Sensor - It didn't help) & P0037 (Heater Control Circuit). I don't think this has anything to do with it. Could it be the coolant temp sensor ? I am going to try cleaning my injectors too. Anybody else have this problem?
How long has your 2008 Dodge Ram 3500 had this problem?
RepairPal Certified shops can diagnose and repair your 2008 Dodge Ram 3500. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
I'm sorry to say that your concern really requires hands on testing using proper diagnostic equipment that is compatible with your Cummins engine.
You'll be guessing forever without doing proper testing. I would definitely not suggest cleaning your injectors.
