7. Align protrusions of fuel tubes with those of fuel injectors.
Insert fuel injectors straight into fuel tubes.
8. After properly inserting fuel injectors, check to make sure that
fuel tube protrusions are engaged with those of fuel injectors,
and that flanges of fuel tubes are engaged with clips.
JEF815Y
9. Tighten fuel tube assembly mounting nuts in numerical
sequence (indicated in the Figure at left) and in two stages.
: Tightening torque N´m (kg-m, ft-lb)
1st stage:
12 - 13 (1.2 - 1.4, 9 - 10)
2nd stage:
17 - 23 (1.7 - 2.4, 13 - 17)
10. Insert fuel hoses into fuel tubes so that ends of fuel hoses butt
up against fuel tubes; fasten with clamps, avoiding bulges.
CAUTION:
After properly connecting fuel tube assembly to injector and
fuel hose, check connection for fuel leakage.

IGNITION TIMINGNLEC0028S06Any of following two methods may be used.
+Method A
a) Attach timing light to loop wire or, combine the three No. 1
ignition coil harnesses and attach the timing light sensor
(attach from above the harness protector) as shown.
b) Check ignition timing.

+On models equipped with air conditioner, checks should
be carried out while the air conditioner is ªOFFº.
+When measuring ªCOº percentage, insert probe more
than 40 cm (15.7 in) into tail pipe.
+Turn off headlamps, heater blower, rear window defogger.
+On vehicles equipped with daytime light systems, set
lighting switch to the 1st position to light only small
lamps.
+Keep front wheels pointed straight ahead.
+If engine stops immediately after starting or idle condition
is unstable, perform the following to initialize IACV-AAC
valve:
a)Stop engine and wait 9 seconds.
b)Turn ignition ªONº and wait 1 second.
c)Turn ignition ªOFFº and wait 9 seconds.
+Make sure the cooling fan has stopped.
