Diagnostic Worksheet
There are many operating conditions that lead to the malfunction
of engine components. A good understanding of such conditions
can make troubleshooting easier and more accurate.
In general, each customer feels differently about a problem. It is
important to fully understand the symptoms or conditions for a
customer complaint.
Utilize a diagnostic worksheet like the one shown below in order to
organize all the information for troubleshooting.

CHECK INJECTION TIMING.
1. Set No. 1 piston at TDC on its com-pression stroke.
2. Remove injection tubes and air bleeder on the back of injection pump.
3. Set dial gauge so its indicator points to somewhere between 1.0 and 2.0 mm
(0.039 and 0.079 in) on the scale.
4. Turn crankshaft two turns clockwise and check that dial gauge indicates the
same value again.
5. Turn crankshaft counterclockwise about 100 degrees, then turn crankshaft
clockwise slowly, and set dial gauge
indicator to 0 mm at the position it
stops.
6. Turn crankshaft clockwise and set it at TDC using the mark on the crankshaft
pulley.
7. Read plunger lift. Plunger lift:0.36   0.02 mm (0.0142   0.0008
in) at TDC
I When repeating the checking, start
with step 5.
NG
EOK
Bleed air from fuel system.
After this inspection,
unnecessary diagnostic
trouble code No. might be
displayed.
Erase the stored memory
in ECM.
Refer to ªHOW TO ERASE
DTCº (EC-344).

INSPECTION END
Adjusting
1. If plunger lift is not within the specified value, adjust by turning injection pump.
I If indication is smaller than the
specified value, turn pump body
away from engine.
I If indication is larger than the speci-
fied value, turn pump body towards
engine.
2. Tighten injection pump securing bolts and nuts.
Nut:
: 20-25N ×m
(2.0 - 2.5 kg-m, 14 - 18 ft-lb)
Bolt:
: 32-42N ×m
(3.3 - 4.3 kg-m, 24 - 31 ft-lb)
3. Remove dial gauge and install air bleeder with new washer.
4. Install injection tubes. Flare nut:
: 20-25N ×m
(2.0 - 2.5 kg-m, 14 - 18 ft-lb)
5. Bleed air from fuel system.

Is engine running?
Ye s
ENoCHECK POWER SUPPLY-I.
1. Turn ignition switch to ªONº posi-
tion.
2. Check voltage between ECM connector terminal
507and
engine ground with
CONSULT-II or voltage tester.
Voltage: Battery voltage
If NG, check the following:
I 10A fuse
I Harness for open or short-circuit
between ECM and ignition switch
If NG, replace 10A fuse or repair
harness or connectors.
OK
Go to q
BªCHECK GROUND CIR-
CUITº.
CHECK POWER SUPPLY-II.
1. Stop engine.
2. Check voltage between ECM connector terminal
325and
engine ground with CON-
SULT-II or voltage tester.
Voltage: Battery voltage

ENG Check the following:
IECM relay
I 20A fuse
I Harness for open or short-circuit
between ECM and battery
I Harness connectors M787, F66
