Injection Nozzle Disassembly
Disassemble the injection nozzle.
1. Nozzle holder
2. Adjusting shim
3. Pressure spring
4. Pressure pin
5. Distance piece
6. Nozzle
7. Retaining ring
Cleaning
Clean the parts in clean test oil.
Injection Nozzle Inspection
1. Check the needle valve, nozzle body, and other
parts for damage.
2. Hold the nozzle body upright and insert approxi-
mately two thirds of the needle valve, and check
that the needle valve drops to the valve seat by
its own weight.

Tightening torque of nozzle body:
29—49 N-m (3.0—5.0 m-kg, 22—36 ft-lb)
2. Check the injection starting pressure, and atomi-
zation. (Refer to page 4D—32.)

IGNITION COIL
INSPECTION
Primary Coil
Use an ohmmeter and check for resistance in the pri-
mary coil. If it is not within the specification, replace
the coil.
Primary coil resistance: (at 20°C 68°F)
FE DOHC...0.72—0.88 Q
Others 1.04—1.27 Q
76G05X-006
Secondary Coil
Use a ohmmeter to measure the resistance of the
secondary coil. If it is not within specification, replace
the coil.
Secondary coil resistance: (at 20°C 68°F)
FE DOHC 10.3—13.9 kQ
Others 7.1— 9.7 k«
76G05X-055
Insulation of Case
Use a 500V megger tester to measure the insula-
tion resistance between the primary terminal and the
case.
The standard reading is 10 MQ or more.
86U05X-046
HIGH-TENSION LEAD
INSPECTION
Measure the resistance using an ohmmeter.
Resistance: 16 kQ per 1m (3.28 ft)

SPARK TEST
1. Disconnect the distributor lead from the distributor.
2. Hold it with insulated pliers approx. 5—10 mm
(0.20—0.39 in) from a ground.
3. Crank the engine and check that a strong blue
spark is visible.
4. If there is no spark, the ignition coil or pick-up coil
may be bad.
Check once again after replacing the ignition coil
or pick-up coil.
IGNITION TIMING
1. Warm up the engine to the normal operating tem-
perature.
2. Turn all electric loads OFF.
3. Connect a tachometer and timing light to the
engine.
4. Connect a jumper wire between the test connec-
tor and ground. (Only for FE DOHC)
5. Check the idle speed. Set to the specified speed
if necessary.
Idle speed: 750 ± 50 rpm (FE DOHC)
800 t58 rpm (F6, F8 FE—MTX)
900 i58 rpm (F8, FE—ATX
in "P" range)
950 -5o rmp (F6—ATX
in "P" range)
6. Check that the timing mark (Yellow) on the crank-
shaft pulley and the mark on the timing belt cover
are aligned.
Ignition timing:
FE DOHC: 12 ± 1° BTDC
(Test connector grounded)
Others: 6 ± 1°
(Vacuum hoses disconnected and
plugged)
