! WARNING Whenever the gasline hoses are removed (other than for pressure testing), the battery must be disconnected to prevent inadvertent activation of the electronic fuel pump.
4. Disconnect the crankcase breather hose from the air filter housing; then remove the air filter assembly from the vehicle.
! WARNING Whenever any maintenance or inspection is performed on the fuel system during which there may be fuel leakage, there should be no welding, smoking, open flames, etc., in the area.
TROUBLESHOOTING 1. Verify that the electric fuel pump is operating by listening for a “whirring” sound for approximately three seconds after the ignition switch is turned to the ON position. If no sound can be heard, see Electric Fuel Pump/Fuel Level Sensor in this section. 2. Check for a flashing EFI icon on the LCD. If EFI is flashing, see ECM Error Codes in the Electrical System section. 3. Make sure there is sufficient, clean gas in the gas tank. 4. Verify that the battery is sufficiently charged to crank the engine over at normal speed. 5. Check the air filter housing and air filter for contamination. Clean or replace as necessary (see the Periodic Maintenance section).
