(7) Connect SST (wire) to the injector and the battery
for 15 seconds, and measure the injection volume
with a graduated cylinder. Test each injector 2 or 3
times.

NOTICE:
Always do the switching at the battery side.
If the injection volume is not as specified, replace the injector.
(c) Inspect leakage (1) In the condition above, disconnect the test probesof SST (wire) from the battery and check the fuel
leakage from the injector.
Fuel drop:
1ZZ±FE1 drop or less in 12 minutes
3ZZ±FE1 drop or less in 5 minutes
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 20 C (68 F)
(b) Inspect fuel pump operation (1) Apply battery voltage to both the terminals. Checkthat 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.

(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 pumpoperates 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 andaround 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.

tion tube sub±assy No. 2.
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 quick connector has
an O±ring which seals the pipe and the connector that
can be contaminated.

Do not use any tool in this operation.

Do not bend or twist the nylon tube.

To protect the tube, cover it with a vinyl or a plastic
bag after checking.

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