Starting a diesel engine after running out of fuel involves a few steps: First, fill the tank with diesel. Then, prime the fuel system by using the primer pump (if available) to remove air. Turn the ignition key to the ‘on’ position without starting the engine to let the fuel pump pressurize the system. Finally, try cranking the engine. Repeat if necessary, but avoid excessive cranking to protect the starter motor.
