Engine Start Switch Method
Turn the key to the ON position. The electric fuel priming pump is activated in this way.
Leave the key in the ON position for 2 minutes. This action allows the fuel system to fully prime.
Do not crank the engine continuously for more than 30 seconds. Allow the starting motor to cool for two minutes before cranking the engine again.
Start the engine. If you cannot start the engine, the engine needs more priming. If the engine continues to misfire or to smoke, more priming is necessary.Engine Mounted Switch Method
Have the engine start switch in the OFF position.

Locate fuel system priming switch (1). The fuel system priming switch is mounted on the base of fuel system primary filter (water separator) (2).Note: When the fuel system priming switch is actuated, power is relayed through the cab, allowing cab functions to power up. It is normal to observe cab functions powering up during this operation.
Raise the fuel system priming switch to the ON position and hold the fuel system priming switch in the ON position for 2 minutes. This switch activates the fuel system priming pump.
