(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.

INSTALLATION
1. INSTALL INJECTORS AND DELIVERY PIPE
(a) Install a new grommet to the injector.
(b) Apply a light coat of gasoline to a new O −ring and install
