! WARNING
Whenever any maintenance or inspection is performed
on the fuel system during which there may be fuel leak-
age, there should be no welding, smoking, open flames,
etc., in the area.
TROUBLESHOOTING
1. Verify that the electric fuel pump is operating by lis-
tening for a "whirring" sound for several 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 DTC (Diagnostic Trouble
Code) on the LCD. If a code is flashing, see appro-
priate Diagnostic Trouble Codes (DTC) in Electrical
System.
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 contami-
nation. Clean or replace as necessary (see Periodic
Maintenance).
REMOVING
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.
1. Remove the front rack and body panel (see Steer-
ing/Frame/Controls).
2. Disconnect the wires from the IAT sensor; then
loosen the clamp and remove the inlet air boot from
the air filter housing.
