Check your glow plugs to be sure they are all connected. There is a bus bar that connects them all together. Make sure all the connections are tight and the plug for them on the lh rear of the head is plugged in. Usually it is a connection issue or a bad glow plug. Do you have DX2 and a multimeter?

They are on the left side of the engine, top of the cylinder head, among the fuel lines. Two up front and two in the back.
