This sounds like a typical glow plug relay failure. The glow plug relay is self contained, it works based on the temperature that it picks up from the aluminum heatsink. There is no input to it that makes it work, it should just work on its own.

Check to make sure you don't have any shorted or open plugs. Replace any plugs that are open or shorted, then replace the glow plug relay.
