Unlike a spark plug that is working continuously while you drive, glow plugs are only needed during the ignition process. The glow plugs work by electrifying the heating element so it heats up and emits visible light (hence the name). Intake air is compressed before the fuel injector spray directs fuel onto the hot tip of the glow plug during the injection of the fuel. The injected fuel mixes with the compressed air to evaporate and start combustion almost simultaneously, even when the engine is cold.

Black smoke is an imbalance in the fuel mixture. Too much fuel and not enough air. There is too much fuel added to the mix and not enough oxygen to burn the fuel correctly. The timing also may be advanced as opposed to retarded. Get a timing light attach it and rotate your distributor until the timing is correct.
There is not enough heat to burn the fuel. The unburnt fuel travels through the exhaust and comes out the back tailpipe as white smoke. A damaged or faulty glow plug module can cause white smoke on engine startup. If the engine has warmed up and there is still white smoke then there may be one or more bad injectors, retarded timing, or a worn injector pump.
