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.

My dad was having similar problems with his '03 Ram/Cummins with only about 120,000 miles on it. It just would not start whether he plugged it in or not. In fact, it didn't even need to be all that cold out. Just a cold engine from not running over night would do it unless it was like 80-90 degrees outside and even then it was maybe 50-50 whether it would start. He was having to use starting fluid more and more often, which can be dangerous. First, he changed the batteries. No luck. Then he changed the grid heater. No Luck. Then he changed the lift pump. Still no luck. I think he even changed the block heater element and still didn't fix it. So he replaced the injectors and that fixed it.
