How do you start a f350 diesel that ran out of diesel?

A diesel engine requires compression to start, and without fuel, there is no compression. Therefore, you cannot start a diesel engine that has run out of diesel by simply adding more fuel.

To start a diesel engine that has run out of diesel, you will need to prime the fuel system. This means filling the fuel lines and injector pump with diesel fuel so that the engine can start.

To prime the fuel system, you will need to:

1. Locate the fuel filter.

2. Loosen the bleed screw on the fuel filter.

3. Pump the fuel primer until diesel fuel comes out of the bleed screw.

4. Tighten the bleed screw.

5. Start the engine.

If the engine does not start, you may need to repeat steps 2-4.

Once the engine is running, you will need to let it run for a few minutes to allow the fuel system to bleed any remaining air.

If you are unable to start the engine after following these steps, you may need to have it towed to a mechanic.
