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 Fuel Pump/
Fuel Level Sensor in this section.
2. Check for a diagnostic trouble code (DTC) on the
LCD. If the light is flashing, see EFI Diagnostic Sys-
tem 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/Tune-Up).

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.
