I'd say the glow plug relay or some glow plugs. Turn your key on and go out and measure voltage from one terminal to the other on the glow plug relay. There should be very little to no voltage showing from one terminal to the other. If there is significant voltage then there is a large voltage drop and the relay is bad. Make sure the relay hasn't clicked off when you are testing it. It will usually stay on for about 2 minutes. After that check the glow plugs for resistance. If you unplug the valve cover wire harnesses the glow plugs are the outer two pins in each connector. They should be around .7 ohms or so if they are good. If they are bad they will most likely be a lot higher than that or just open.
