Note: The fuel system needs to be primed under certain conditions.
*Before starting the engine for the first time
*After running out of fuel and fuel has been added to the fuel tank
*After fuel system maintenance such as changing the fuel filter and draining the fuel/water separator, or replacing a
fuel system component
To prime the fuel system:
1.Turn the key to the ON position for 10 to 15 seconds. This will allow the electric fuel pump to prime the fuel
system.
2.NEVER use the starter motor to crank the engine in order to prime the fuel system. This may cause the starter
motor to overheat and damage the coils, pinion and / or ring gear.
