            A set of new glow plugs will do nothing for you if your glow plug controller is not working! On early applications such as the GM 6.2L and early 6.5L the glow plug controller determines the length of the pre-glow cycle and also may cycle the plugs after the engine is running for the first minute or so to help smooth operation. On later applications such as the 6.5L and LB7 Duramax, the PCM determines the length and timing of the glow cycle and the glow plug controller mostly functions as a relay controlling the current flow to the glow plugs.
