ON-VEHICLE INSPECTION
1. CHECK FUEL PUMP OPERATION
(a) Connect the intelligent tester to the DLC3.
(b) Turn the ignition switch ON. 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
operate. Check the fuel pump circuit (see page FU-
33).
2. CHECK FUEL PRESSURE
(a) Check that the battery positive voltage is above 12
V.
(b) Discharge the fuel system pressure (see page FU-
9).
(c) Disconnect the cable from the negative (-) battery
terminal.
(d) Disconnect the fuel main tube (see page FU-10).
(e) Install SST (pressure gauge) as shown in the
illustration.
SST 09268-31011 (95336-08070, 90467-13001,
09268-41500), 09268-45014 (09268-41200,
09268-41220, 09268-41250)
(f) Wipe off any gasoline.
(g) Reconnect the cable to the negative (-) battery
terminal.
(h) Start the engine.
(i) Measure the fuel pressure at idle.
Fuel pressure:
304 to 343 kPa (3.1 to 3.5 kgf/cm
2, 44 to 50 psi)
If the pressure is not as specified, check the fuel
pump and injectors.
(j) After checking the fuel pressure, disconnect the
cable from the negative (-) battery terminal and
carefully remove SST and the fuel tube connector to
prevent fuel from spilling.
(k) Reconnect the fuel main tube (see page FU-14).
(l) Check for fuel leaks (see page FU-14).

(3) Checking the contact pressure of the terminal:
Prepare a spare male terminal. Insert it into a
female terminal, and check for ample tension
when inserting and after full engagement.
NOTICE:
When testing a gold-plated female terminal,
always use a gold-plated male terminal.
(d) REPAIR METHOD OF CONNECTOR TERMINAL
(1) If there is any foreign matter on the terminal,
clean the contact point using an air gun or cloth.
Never rub the contact point using sandpaper as
the plating may come off.
(2) If there is abnormal contact pressure, replace
the female terminal. If the male terminal is gold-
plated (gold color), use a gold-plated female
terminal; if it is silver-plated (silver color), use a
silver-plated female terminal.
(3) Damaged, deformed, or corroded terminals
should be replaced. If the terminal does not lock
into the housing, the housing may have to be
replaced.
(e) HANDLING OF WIRE HARNESS
(1) If removing a wire harness, check the wiring and
clamping before proceeding so that it can be
restored in the same way.
(2) Never twist, pull or slacken the wire harness
more than necessary.
(3) The wire harness should never come into
contact with a high temperature part, or rotating,
moving, vibrating or sharp-edged parts. Avoid
contact with panel edges, screw tips and other
sharp items.
(4) When installing parts, never pinch the wire
harness.
(5) Ne ver c ut or break th e c ov er of t he w ir e har ness .
If it is cut or broken, repair the cover with vinyl
tape or replace the wire harness.
2. CHECK FOR OPEN CIRCUIT
(a) For an open circuit in the wire harness in Fig. 1,
check the resistance or voltage, as described below.

(b) Remove the gasket from the exhaust manifold.
INSTALLATION
1. INSTALL FRONT EXHAUST PIPE ASSEMBLY
