Electronic Fuel Injection

! 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.
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 sec-
tion.
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.

tion 2).
REMOVING THROTTLE BODY
1. Turn the ignition switch to the OFF position; then

center console and disconnect the battery.

throttle position sensor (TPS) connector (A), man-
ifold absolute pressure (MAP) sensor connector

4. Remove the cap screws securing the throttle body
to the manifold; then lift the throttle body off the
manifold. Account for an O-ring.

cover to the throttle body; then remove the cover.
