Installing New Glow Plugs Will Fix Cold Start Woes
Since diesels are compression-ignition engines, meaning there are no spark plugs to start the combustion process, nearly every diesel is equipped with some sort of glow plug system to get the fire started in cold weather. The little “Wait to Start” light that comes on usually indicates that the factory glow plug system is activated as part of the cold start circuit. Today’s computer-controlled engines have taken the glow plug system engagement to an all-new level, taking into account the various engine parameters as to when the glow plugs will be activated or not.
