It was -25F, 2 days last week in WI. I use a Frost Heater and the car started like it was +70F outside! Getting it up to operating temp, thats another story, it never happened.

Bring the battery inside for the night and it will start.

Not if the engine is too cold.

If the glow plugs work and the battery good and is at room temperature, yes it will work. Try it. It's amazing how much power a really cold battery looses.

It doesn’t matter how strong the battery is. If the charge air is too cold, it will not reach the auto ignition temperature. Refer to my previous post about the tow truck driver.

Perhaps he flooded that engine by trying to first crank it with a dead battery or a half changed booster pack. The glow plugs, when working, will create the hot spot that diesel needs (when the mixture is correct) to get running. A block heater will not warm up the intake air temperature so the "too cold air" theory isn't holding up. It will however make the engine spin faster. You need around 650rpms to start a diesel so that's anther reason to start with a fully charged and warm battery.

At what intake air temperature is it impossible to start an engine?
