(d) Observe the following precautions when removing and
installing the injectors.
(1) Never reuse the O −ring.
(2) When placing a new O −ring on the injector, take
care not to damage it in any way.
(3) Coat a new O −ring with spindle oil or gasoline be-
fore installing −never use engine, gear or brake oil.
(e) Install the injector to the delivery pipe and intake manifold
as shown in the illustration.
(f) Check that there are no fuel leaks after doing mainte- nance anywhere on the fuel system.
(1) Remove the fuse cover on the instrument panel.
(2) Connect the TOYOTA hand− held tester to the
DLC3.
(3) Turn the ignition switch ON and TOYOTA hand −
held tester main switch ON.
NOTICE:
Do not start the engine. (4) Select the active test mode on the TOYOTA hand−held tester.
(5) Please refer to the TOYOTA hand −held tester oper-
ator ’s manual for further details.
If you have no T OYOTA hand−held tester, connect the positive
(+) and negative ( −) leads from the battery to the fuel pump con-
nector (See page SF−14 ).
(6) Pinch the fuel return hose. The pressure in the high
pressure line will rise to approx. 392 kPa (4 kgf/cm
2,
57 psi). In this state, check to see that there are no
leaks from any part of the fuel system.
NOTICE:
Always pinch the hose. Avoid bending as it may cause the
hose to crack.
(7) Turn the ignition switch to LOCK.
(8) Disconnect the TOYOTA hand −held tester from the
DLC3.

(f) Install the grommet and O−ring to the injector.
(g) Connect SST (union and hose) to the injector, and hold
the injector and union with SST (clamp).
SST 09268−41046
(h) Put the injector into the graduated cylinder.
HINT:
Install a suitable vinyl hose onto the injector to prevent gasoline
from splashing out.
(i) Remove the fuse cover on the instrument panel.
(j) Connect the TOYOTA hand−held tester to the DLC3.
(k) Turn the ignition switch ON and TOYOTA hand−held tes-
ter main switch ON.
NOTICE:
Do not start the engine.
(l) Select the active test mode on the TOYOTA hand −held
tester.
(m) Please refer to the TOYOTA hand −held tester operator’s
manual for further details.
(n) If you have no TOYOTA hand−held tester, connect the positive (+) and negative (−) leads from the battery to the
fuel pump connector (See page SF−14)
(o) Connect SST (wire) to the injector and battery for 15 se- conds, and measure the injection volume with a gra-
duated cylinder. Test each injector 2 or 3 times.
SST 09842−30070
Volume:
69 − 88 cm
3 (4.2 − 5.4 cu in.) per 15 seconds
Difference between each injector:
5 cm
3 (0.3 cu in.) or less
If the injection volume is not as specified, replace the injector.
2. INSPECT LEAKAGE
(a) In the condition above, disconnect the test probes of SST (wire) from the battery and check the fuel leakage from
the injector.
SST 09842−30070
Fuel drop: One drop or less per minute
(b) Turn the ignition switch to LOCK.
(c) Disconnect the negative ( −) terminal cable from the bat-
tery.

wheel to the opposite full lock and keep it there for 2 −3 se-
conds.
(b) Repeat (a) several times.
