Engine Out of Fuel – How to Restart

Engine Out of Fuel – How to Restart - Ops #3499

When an engine has run out of fuel, there is a definite procedure to follow when restarting it.

Note: Never use the starting motor and fuel pump to prime the fuel filters. Prolonged use of the starting motor and fuel pump to prime the fuel system can result in damage to the starter, fuel pump, and injectors.

Use the following procedure to prime the fuel system:

  1. Fill the fuel tank with the recommended grade of fuel. If only partial filling is possible, add a minimum of 10% of the total tank volume of fuel to the tank. For example, a 150-gallon tank would require a minimum of 15 gallons of fuel.
    Note: If a vehicle is on uneven ground, more fuel may be required.
  2. Connect a Detroit-approved priming tool or operate the engine-mounted hand primer for three minutes or 250 strokes.
  3. Turn on the ignition switch.
  4. Wait for the engine system indicator lights on the instrument panel to go out.
  5. With the accelerator pedal in the idle position, start the engine.
  6. Crank engine for 20 seconds.
  7. If engine does not start, allow for a 60-second cool down and repeat previous step.
    Note: The starting cycle can be repeated up to three times.
  8. Monitor the oil pressure gauge or indicator lamp. Keep the engine running at an idling speed until a stable oil pressure reading of 97 kPa (14 psi) or more is maintained for one minute.
  9. Check for leaks.
  10. Allow the engine to reach operating temperature of 60° C (140° F).
  11. Increase engine speed to 1800 rpm for three minutes.
    Note: Increasing engine speed above idle before oil pressure has stabilized may cause severe engine damage.
  12. Return the engine to idle and allow to idle for approximately one minute, then shut down the engine.
  13. Check for leaks.
  14. If engine still fails to start, contact an authorized Detroit™ repair facility.
