REMOVAL
1. DISCHARGE FUEL SYSTEM PRESSURE
CAUTION:
• DISCHARGE FUEL SYSTEM PRESSURE
procedures must be performed before
disconnecting any part of the fuel system.
• After performing the DISCHARGE FUEL SYSTEM
PRESSURE procedures, pressure will remain in
the fuel line. When disconnecting the fuel line,
place a cloth or equivalent over fittings to reduce
the risk of fuel spray.
(a) Remove the console box (see page IR-83).
(b) Disconnect the connector.
(c) Start the engine. After the engine has stopped, turn
the ignition switch off.
HINT:
DTC P0171 (system too lean) may be set.
(d) Check that the engine does not start.
(e) Remove the fuel tank cap, and let the air out of the
fuel tank.
(f) Connect the connector.
(g) Install the console box (see page IR-90).
2. DISCONNECT CABLE FROM NEGATIVE BATTERY
TERMINAL
CAUTION:
Wait at least 90 seconds after disconnecting the
cable from the negative (-) battery terminal to

SST 09842-30080
Standard injection volume:
76 to 92 cm
3 (4.6 to 5.6 cu in.) per 15
seconds
Standard difference between each injector:
16 cm
3 (1.0 cu in.) or less
(c) Inspect the fuel leakage.
(1) Disconnect the SST (wire) tester probes from
the battery and check the fuel leakage from the
injector.
Standard fuel drop:
