Which conditions ???

Of course Diesel engine doesn't need any sparkling !

I do not believe a such low compression engine can make dieseling while we try to stop it. But I do believe because it internal switching power supply & voltage regulation, the MSD can keep working during very short period even if you turn if off.

Even with new and perfect injectors, the CIS always leave some unburnt fuel in the intake path. Porsche fitted the car with a temporised relay on purpose !
