TROUBLESHOOTING

1. Verify that the electric fuel pump is operating by lis-

tening 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 ECU Error Codes in Section 5.

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 contam-

ination. Clean or replace as necessary (see Section

2).

REMOVING THROTTLE BODY

1. Turn the ignition switch to the OFF position; then

remove the ignition switch key.

2. Remove the seat, seat back, and seat base; then dis-

connect the battery.

3. Remove the air inlet boot between the air filter and

throttle body; then disconnect the MAP sensor con-

nector (A), fuel injector connector (B), and ISC con-

nector (C).

HDX043A

4. Remove the screw from the throttle arm cover and

remove the cover; then loosen the jam nut and dis-

connect the throttle cable.

! WARNING

Whenever the gasline hoses are removed (other
than for pressure testing), the battery must be dis-
connected to prevent inadvertent activation of the
electronic fuel pump.

! WARNING

Whenever any maintenance or inspection is per-
formed on the fuel system during which there may
be fuel leakage, there should be no welding, smok-
ing, open flames, etc., in the area.

! WARNING

Do not turn the ignition switch to the ON position
with the hoses removed. Gasoline will be pumped by
the electric fuel pump causing a safety hazard.
