Diesel still ignites the fuel. Poor ignition could be from any number of
things. Injectors/injector pump, compression, valves, carbon build up.
They just don't have an electrical ignition system. Or at least that is how
I read that statement about less efficient ignition??

OP is asking about a diesel engine. *Probably* not an ignition problem.
