Keeping Diesel Engine Warm
My dodge dually Cummins engine is very hard to start when cold. At home or camping with hookups I can plug in the block heater but what can be done when boondocking.

How cold is cold? As others have mentioned.....is your intake grid heater working at all or properly? We can and have “many” times started ours at -20 F. Until you get it checked-out....you may try “cycling” the grid-heater twice and then attempt a start.rhagfo wrote:
Describe cold, 40, 30, 0 or colder.
You may be right. Im in southern AZ so cold is 40s and 50s.
Will replace the heater grid first.
Slow down there. Grid heater has nothing to do with it in those temps.
If it’s hard starting when “cold” or basically room temp in your case, 99% chance it’s injectors. Especially if it lights off fine warm or plugged in.
