Diesel engines require a really high ampherage output to crank, so you won't get much action from under the hood if the battery is dead or near dead.

Also unlikely that a "jump" will work, except from another diesel. Even from a tow truck's cables, which are set to start gasoline engines and won't generate enuf cranking power for you.

I'd also suggest you don't give a gas powered vehicle a jump from your diesel. Amps could fry some electronics.
