Running Out of Fuel for GMC Truck Sierra Classic - 2WD 2007

If the engine stalls and you think that you have run out of fuel, do this to restart the engine:

Caution: Diesel fuel is flammable. It could start a fire if it gets on hot engine parts. You could be burned. Do not let too much fuel flow from the air bleed valve, and wipe up any spilled fuel with a cloth.

1. If parked on a level surface, add at least two gallons of fuel. However, if parked on a slope, up to five gallons of fuel might need to be added.
2. Follow the fuel priming procedure earlier in this section to prime the fuel filter.
3. Close the air bleed valve.
4. Turn the ignition key to START for 10 to 15 seconds at a time until the engine starts. If the engine tries to run, but does not run smoothly, increase the rpm a little using the accelerator pedal. This will help force air through the system.

If the engine stalls and you think that you may have run out of fuel, do this to restart the engine:

1. If parked on a level surface, add at least one gallon of fuel. However, if parked on a slope, up to five gallons of fuel might need to be added.
2. Follow the vehicle fuel system priming procedure earlier in this section to re-prime the system and re-start the engine.

The check engine light may come on if the vehicle has run out of fuel. This light may stay on for a few drive cycles after the condition is corrected, but will eventually clear itself.

The fuel operated heater stops automatically when the fuel tank volume is less or equal to 10 percent of the total tank volume. If the vehicle runs out of fuel, the FOH fuel lines will not need to be primed because they will still have fuel remaining.
