6 Check ignition timing.
PREPARATION:
(a) Warm up the engine to normal operating temperature.
(b) Shift the transmission into the N position.
(c) Keep the engine speed at idle.
(d) Using SST, connect terminals TE1 and E1 of the DLC1.
SST 09843±18020
(e) Using a timing light, connect the tester to the No.1 high±
tension cord.
CHECK:
Check the ignition timing.
OK:
Ignition timing: 10° BTDC at idle

7 Check fuel pressure.
PREPARATION:
(a) Be sure that enough fuel is in the tank.
(b) Connect the TOYOTA hand±held tester to the DLC3.
(c) Turn the ignition switch ON and push TOYOTA hand±held
tester main switch ON.
(d) Use the ACTIVE TEST mode to operate the fuel pump.
(e) Please refer to the TOYOTA hand±held tester operator's
manual for further details.
(f) 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±6).
CHECK:
Check for fuel pressure in the fuel inlet hose when it is pinched
off.
HINT:
At this time, you will hear a fuel flowing noise.
NG Proceed to page SF±6 and continue to trouble-
shoot.

8 Check for spark.
PREPARATION:
(a) Disconnect the high±tension cord from the spark plug.
(b) Remove the spark plug.
(c) Install the spark plug to the high±tension cord.
(d) Disconnect the injector connector.
(e) Ground the spark plug.
CHECK:
Check if spark occurs while the engine is being cranked.
NOTICE:
To prevent excess fuel being injected from the injectors
during this test, don't crank the engine for more than 5 ~ 10
seconds at a time.
