well if you google your engine you will get the specs for testing the glow plugs...it's checks ohms. If it's not the glow plugs, by the black smoke it seems like a timing problem. Drain some of the fuel and check for water. It will seperate from the diesel...Check the glow plug circuit for blown fuses or relays. Does the pump come on?
