ON-VEHICLE INSPECTION
1. CHECK FUEL PUMP OPERATION
(a) Connect the intelligent tester to the DLC3.
(b) Turn the ignition switch ON.
NOTICE:
Do not start the engine.
(c) Select the following tester menus: DIAGNOSIS,
ENHANCED OBD II, ACTIVE TEST and FUEL
PUMP/SPD. Operate the fuel pump.
(d) Touch the fuel hose in the engine compartment to
check the fuel flow, and you will be able to hear the
sound of the fuel pump.
(e) Stop the fuel pump. If there is no fuel flow, the fuel
pump may not be operating. Check the fuel pump
circuit.
2. CHECK FUEL PRESSURE
(a) Check that the battery positive voltage is above 12
V.
(b) Perform the "DISCHARGE FUEL SYSTEM
PRESSURE" procedures (see page FU-1).
(c) Disconnect the cable from the negative (-) battery
terminal.
(d) Disconnect the fuel main tube (see page FU-22).
(e) Install SST (pressure gauge) using SST and a fuel
tube connector as shown in the illustration.
SST 09268-41048 (90467-13001, 95336-08070,
09268-41500), 09268-45014 (09268-41200,
09268-41220, 09268-41250)
(f) Wipe up any gasoline.
(g) Reconnect the cable to the negative (-) battery
terminal.
(h) Start the engine.
(i) Measure the fuel pressure at idle.
Standard fuel pressure:
304 to 343 kPa (3.1 to 3.5 kgf/cm
2,44.1 to 49.7
psi)
• If the fuel pressure is greater than the standard
value, replace the fuel pump.
• If the fuel pressure is less than the standard
value, check the connection of the fuel hose and
the fuel pump.
(j) Stop the engine.
(k) Check that the fuel pressure remains as specified
for 5 minutes after the engine stops.
Standard fuel pressure:
147 kPa (1.5 kgf/cm
2, 21 psi) or more
If the fuel pressure is not as specified, check the fuel
pump or fuel injector.
(l) After checking the fuel pressure, carefully
disconnect the negative (-) battery cable, and
remove SST and fuel tube connector to prevent
gasoline from splashing.
(m) Reconnect the fuel main tube (see page FU-29).

REMOVAL
CAUTION:
Do not allow fuel to spray when removing the pipe
between the high pressure side fuel pump and the fuel
injector. The fuel in the pipe is highly pressurized.
1. DISCHARGE FUEL SYSTEM PRESSURE
CAUTION:
• The "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 IP-16).
(b) Start the engine. After the engine has stopped, turn
the ignition switch OFF.
HINT:
DTC P0171/P0172 (system too lean) may be set.
(c) Check that the engine does not start.
(d) Remove the fuel tank cap, and let the air out of the
fuel tank.
(e) Connect the connector.
(f) Install the console box (see page IP-23).
2. DISCONNECT CABLE FROM NEGATIVE BATTERY
TERMINAL
CAUTION:
Wait at least 90 seconds after disconnecting the
cable from the negative (-) battery terminal to
prevent airbag and seat belt pretensioner activation.
3. REMOVE ENGINE ASSEMBLY
(a) Remove the engine (see page EM-21).
4. REMOVE INTAKE AIR SURGE TANK ASSEMBLY
(See page EM-27)
5. DISCONNECT FUEL MAIN TUBE
(a) Remove the No. 2 fuel pipe clamp.

(b) Pinch the tube connector and then pull out the fuel
pipe.
NOTICE:
• Check for foreign matter in the fuel tube
around the fuel tube's connector. Clean it if
necessary. Foreign matter can affect the O-
ring's ability to seal the connector and fuel
main pipe.
• Do not use any tools to separate the
connector and pipe.
• Do not forcefully bend or twist the hose.
• Keep the connector and pipe free from
foreign matter.
• If the connector and pipe are stuck together,
pinch the connector and turn it carefully to
disconnect it.
• Put the connector in a plastic bag to prevent
damage and contamination.
6. REMOVE FUEL INJECTOR ASSEMBLY
(a) Disconnect the 6 injector connectors.
(b) Remove the 5 bolts and fuel delivery pipe together
with the 6 injectors.
NOTICE:
Be careful not to drop the fuel injectors when
removing the fuel delivery pipe.
(c) Remove the 6 insulators from the intake manifold.

INSPECTION
1. INSPECT FUEL INJECTOR ASSEMBLY
(a) Inspect injector resistance.
(1) Measure the resistance between the terminals.
Standard resistance:
11.6 to 12.4
at 20C (68F)
If the result is not as specified, replace the
injector.
(b) Inspect the injection volume.
CAUTION:
This test involves high-pressure fuel and
electricity. Take every precaution regarding safe
handling of both the fuel and the electricity.
Perform this test in a safe area, and avoid any
sparks or flames. Do not smoke.
(1) Install the fuel tube connector to SST (hose),
then connect the tube connector to the fuel
pipe (vehicle side).
SST 09268-41048 (95336-08070, 09268-

(4) Put the injector into the graduated cylinder.
CAUTION:
Install a suitable vinyl tube onto the injector
to contain gasoline spray.
(5) Operate the fuel pump.
(6) Connect SST (wire) to the injector and the
battery for 15 seconds, and measure the
injection volume with the graduated cylinder.
Test each injector 2 or 3 times.
SST 09842-30080
Standard volume:
