INSPECTION
1. INSPECT FUEL INJECTOR ASSY
NOTICE:
This inspection aims at inspecting the fuel injectors for open or short, because the fuel injectors of
this vehicle are high±pressure type and do not allow to inspect fuel injection volume.
(a) Inspect injector resistance
(1) Using an ohmmeter, measure the resistance between the terminals.
Resistance: 2.55 to 2.85at 20C (68F)
If the resistance is not as specified, replace the injector.
2. INSPECT FUEL PUMP
(a) Insect fuel pump resistance.
(1) Using an ohmmeter, measure the resistance be-
tween the terminals.
Resistance: 0.2 to 3.0  at 20C (68F)
(b) Inspect fuel pump operation
(1) Apply battery voltage to both the terminals. Check
that the pump operates.
NOTICE:

These tests must be done quickly (within 10 seconds)
to prevent damage to the pump.

Keep fuel pump as far away from the battery as pos-
sible.

Always do the switching at the battery side.
3. INSPECT FUEL PUMP (HIGH PRESSURE)
(a) Remove the engine cover.
(b) Disconnect the fuel pump connector.
(c) Using an ohmmeter, measure the resistance between the
terminals.
Resistance: 1.19 to 1.39  at 20C (68F)
If the resistance is not as specified, replace the fuel pump.
(d) Reconnect the connector.
(e) Reinstall the engine cover.

1.CHECK FUEL PRESSURE
(a)Discharge the pressure in the fuel system and take pre-
cautions for possible fuel spillage. (See page 11±30)
(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±28160
(e) Disconnect the fuel tube clamp from the fuel tube connec- tor.
(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:
196 to 588 kPa (2 to 6 kgf/cm
2, 28 to 85 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:
196 to 588 kPa (2 to 6 kgf/cm
2, 28 to 85 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 CHECK FOR
FUEL LEAKS
(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. DISCONNECT FUEL TANK RETURN TUBE (1AZ±FSE ENGINE TYPE)
(a) Remove the tube joint clip, and pull out the fuel return tube.
NOTICE:

Check if there is any dirt or mud around the connector
before this operation and remove the dirt as neces-
sary.

Be careful of mud because the fuel tube joint has an
O±ring which seals the pipe and connector that can
be contaminated.

Do not use any tool in this operation.

Do not bend or twist the nylon tube. Protect the con-
nector by covering it with a vinyl or plastic bag.

When the pipe and connector are stuck, push and pull
the connector to release and pull the connector out
carefully.
