Anyways, heres how to start a 737-800 1. Turn on the Main Battery. 2. Select either of the Left Main fuel pump switches to the "ON" position. 3. Select the APU switch to the "START" position. Monitor the APU Exhaust Gas Temperature gauge for stabilization. 4. With the APU fully powered up, select the APU Bleed switch to the "ON" position to provide pneumatic air to the bleed system. 5. Select the Isolation Valve switch to the "ON" position. This will open the pneumatic duct for APU Bleed-air to the Engine 2 start valve. 6. Turn on any of the Right Side Fuel pumps. 7. Close the overhead, and select "Shift + 4" to call up the throttle stack. 8. Select the Eng2 starter knob to the "Ground" position. Start valve Open light will illuminate for Eng2. 9. Monitor Eng2 N2 (make sure the secondary engine indications are visible). At around 19-20% N2, turn on the right side engine valve to the "IDLE" position. 10. Open the overhead again, and turn the Isolation valve to the "OFF" position. 11. Right side fuel is already selected for the APU. 12. Close the overhead. 13. Select the Eng1 starter knob to the "Ground" position. Start Valve Open light will illuminate for Eng1. 14. Monitor Eng1 N2. At around 19-20% N2, turn on the left side engine valve to the "IDLE" position. 15. Turn the APU Bleed Valve to the "OFF" position. 16. With both engines running, you may now turn the APU off by selecting the "OFF" position of the APU switch. 17. Turn on both Eng1 and Eng2 Bleed air valves and select packs on if desired. 18. Select the fuel pumps to your desired tank. The center tank is used first in most all conditions. 19. Turn on both Engl and Eng2 Hydraulic switches. 20.
