Glow plugs are not staying on long enough to warm. Check voltage at the glow plug strip when glow plug is selected. If it goes out almost immediately, the glow plug timer is bad. A timer is used to keep glow plugs from staying on and melting! I don't know where it is located on the Cat,but it will have one, could be called glow plug controller.
