ON±VEHICLE INSPECTION
1.CHECK FUEL PRESSURE
(a)Discharge the pressure in the fuel system and take pre-
cautions for possible fuel spillage.(See page 11±15)
(b) Check that the battery voltage is above 12 V.
(c) Disconnect the negative (±) battery cable.
(d) Pull out the connecter from a new fuel tube.
HINT:
Part No. 23901±0H040
(e) Remove the fuel pipe clamp No.1 from the fuel tube con- nector.
(f) Disconnect the fuel tube connector from the fuel pipe while pinching part A with fingers as shown in the illustra-
tion.
CAUTION:
Do not disconnect the fuel tube connector (quick
type) until after you have discharged the fuel system
pressure and taken appropriate steps to prevent fuel
spillage.
There may be remained pressure in the fuel lines after
discharging the pressure.
Take precautions to prevent fuel from spraying on
you or your clothing or inside the engine compart-
ment.

(h) Wipe up any gasoline.
(i) Reconnect the negative (±) battery cable.
(j) Connect the hand±hand tester to the DLC3.
(k) Measure the fuel pressure.
Fuel pressure:
304 to 343 kPa (3.1 to 3.5 kgf/cm
2, 44 to 50 psi)
If pressure is high, replace the fuel pressure regulator.
If pressure is low, check the fuel hoses connections, the fuel
pump, the fuel filter and the fuel pressure regulator.
(l) Disconnect the hand±held tester from the DLC3.
(m) Start the engine.
(n) Measure the fuel pressure at idle.
Fuel pressure:
304 to 343 kPa (3.1 to 3.5 kgf/cm
2, 44 to 50 psi)
(o) Stop the engine.
(p) Check that the fuel pressure remains as specified for 5
minutes after the engine has stopped.
Fuel pressure:147 kPa (1.5 kgf/cm
2, 21 psi) or more
If pressure is not as specified, check the fuel pump, the pres-
sure regulator and/or the injectors.
(q) After checking the fuel pressure, disconnect the negative
(±) battery cable and carefully remove SST and the fuel
tube connector to prevent gasoline from splashing.
(r) Reconnect the No. 1 fuel pipe (fuel tube connector).
CAUTION:
After taking the precautions, connect the fuel tube con-
necter (quick type).
2. CHECK FUEL PUMP OPERATION AND FUEL LEAK
(a) When using the hand±held tester
(1) Connect the hand±held tester to the DLC3.
(2) Turn the ignition switch ON and the hand±held tes-
ter main switch ON.
NOTICE:
Do not start the engine.
(3) Select the active test mode on the hand±held tester.
(4) Perform the active test. Check that the fuel pump
operates and check for fuel leaks.

(4) Turn SST, align the retainers inside the connector
with SST chamfered parts and insert SST into the
connector.
(5) Slide SST and the connector together towards the
fuel tube assembly.
(e) Observe these following precautions when disconnecting
the fuel tube connector (quick type).
(1) Remove the fuel pipe clamp No.1.
(2) Check that there is no dirt or mud on the pipe and
around the connector before disconnecting them.
Clean them if necessary.
(3) Disconnect the connector from the hose while
pinching part A with fingers as shown in the illustra-
tion.
(4) When the connector and the pipe are stuck, push
and pull the connector to release and pull the con-
nector out from the pipe carefully.
(5) Inspect that there is no dirt or mud on the sealing
surface of the disconnected pipe. Clean it away if
necessary.
(6) To prevent the disconnected pipe and connector
from being damaged and foreign objects from being
introduced, cover them with a vinyl or plastic bag.

(f)Observe these precautions when connecting the fuel tube connectors (Quick Type):
(1)Check that there is no damage or foreign objects inthe connected part of the pipe.
(2)Match the axis of the connector with the axis of the pipe, and push into the connector until the connec-
tor makes a ºclickº sound. If the connection is tight,
apply little amount of fresh engine oil on the tip of the
pipe.
(3)After having finished the connection, check if the pipe and the connector are securely connected by
pulling on them.
(4)Check for fuel leaks.
4.CHECK FOR FUEL LEAKS
(a)Check that there are no fuel leaks after doing maintenance anywhere on t\
he fuel system. (See page 11±19)

(a)Inspect injector resistance (1)Using an ohmmeter, measure the resistance be-tween the terminals.
Resistance:
EngineRersistanceCondition
1ZZ±FE13.4 to 14.2 20 C (68 F)
3ZZ±FE13.8 to 15.2 20 C (68 F)
If the resistance is not as specified, replace the injector.
(b)Inspect injector inspection
CAUTION:
This test involves high±pressure fuel and electricity. Take
every precaution regarding safe handling of both the fuel
and the electricity. Preform this test in a safe area, and
avoid any sparks or flame. Do not smoke.
(1)Obtain new No. 1 fuel pipe (part No. 23901±0D030)and remove the fuel tube connector from the pipe.
(2)Install the fuel tube connector to SST (hose), then connect the tube connector and the fuel pipe.
SST09268±41047 (95336±08070)
CAUTION:
Connect the fuel tube connector (quick type) after observ-
ing the precautions to prevent fuel from spraying.
(3)Install the O±ring to the injector.
(4)Connect SSTs (union and hose) to the injector, andhold the injector and the union with SST (clamp)
SST09268±41047 (95336±08070, 09268±41110, 09268±41300)
(5)Put the injector into a graduated cylinder.
CAUTION:
Install a suitable vinyl tube onto the injector to contain gas-
oline spray.
(6)Operate the fuel pump.(See Page 11±5)
