No. Iginition in a Diesel engine comes from compression and not spark. Once the Diesel engine is running you do not need electricitry to keep it running. However, modern diesel engines have computers controlling many of the functions of the engine and that would cause it to fail if there was no electricity. Old diesel engines did not have computers and would keep running even if your battry went flat because your alternator died. Just dont turn it off because the starter needs electricity :P
