1999 NISSAN PRIMERA fuel filter

Precautions
lBefore connecting or disconnecting the ECM harness
connector, turn ignition switch OFF and disconnect
negative battery terminal. Failure to do so may damage
the ECM because battery voltage is applied to ECM even
if ignition switch is turned off.
lWhen connecting ECM harness connectors, push in
both sides of the connector until you hear a click.
Maneuver the lever until you hear the three connectors
on the inside click. Refer to the figure at left.
lBefore replacing ECM, perform Terminals and Reference
Value inspection and make sure ECM functions properly.
Refer to EC-CD-52.
lIf MI illuminates or blinks irregularly during engine
running, water may have accumulated in fuel filter. Drain
water from fuel filter. If this does not correct the problem,
perform specified trouble diagnostic procedures.
lAfter performing each TROUBLE DIAGNOSIS, perform
ªOVERALL FUNCTION CHECKº or ªDTC (Diagnostic
Trouble Code) CONFIRMATION PROCEDUREº.
The DTC should not be displayed in the ªDTC CONFIR-
MATION PROCEDUREº if the repair is completed. The
ªOVERALL FUNCTION CHECKº should be a good result
if the repair is completed.

PRECAUTIONS AND PREPARATIONCD20T
EC-7

Basic Inspection
Precaution:
Perform Basic Inspection without electrical or mechanical
loads applied;
lHeadlamp switch is off,
lAir Conditioner switch is off,
lRear defogger switch is off,
lSteering wheel is in the straight-ahead position, etc.
BEFORE STARTING
1. Check service records for any
recent repairs that may indicate a
related problem, or the current need
for scheduled maintenance.
2. Open engine hood and check the
following:
lHarness connectors for faulty con-
nections
lVacuum hoses for splits, kinks, or
faulty connections
lWiring for faulty connections,
pinches, or cuts
3. Using priming pump, bleed air from
fuel system. Refer to ªFuel Filter
Checkº in MA section.
CONNECT CONSULT-II TO THE
VEHICLE.
Connect ªCONSULT-IIº to the data link
connector for CONSULT-II and select
ªENGINEº from the menu. Refer to EC-
CD-27.
DOES ENGINE START?
Ye s
ENo
Turn ignition switch to
the ªLOCKº position, wait
5 seconds and then start
engine. If engine fails to
start, check malfunction
item.
Run engine for 10 minutes.
CHECK IDLE SPEED.
Read engine idle speed in
ªDATA MONITORº mode with
CONSULT-II.
825 rpm   25 (in N position)
---------------------------------------------------------------------------------------------------------------------------------OR---------------------------------------------------------------------------------------------------------------------------------
Check idle speed using tachom-
eter tester.

CHECK INJECTION TIMING.
1. Set No. 1 piston at TDC on its com-
pression stroke.
TDC: Without painted mark
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 2 turns clockwise
and check that dial gauge indicates
the same value again.
5. Turn crankshaft counterclockwise
about 100 degrees, then turn crank-
shaft slowly clockwise, and set dial
gauge indicator to 0 mm at the posi-
tion it stops.
6. Turn crankshaft clockwise and set it
at plunger lift timing mark using the
mark on the crankshaft pulley.
plunger lift timing mark: Yellow
painted mark
7. Read plunger lift.
Plunger lift:
0.89   0.08 mm (0.0350   0.0031
in) at plunger lift timing mark
lWhen repeating the checking,
start with step 5.

Adjusting
1. If plunger lift is not within the speci-
fied value, adjust by turning injec-
tion pump.
lIf indication is smaller than the
specified value, turn pump body
away from engine.
lIf indication is larger than the
specified value, turn pump body
towards engine.
2. Tighten injection pump securing
bolts and nuts.
Nut:
: 20-25N´m
(2.0 - 2.6 kg-m, 15 - 18 ft-lb)
Bolt:
: 25-35N´m
(2.6 - 3.6 kg-m, 18 - 26 ft-lb)
3. Remove dial gauge and install air
bleeder with new washer.
4. Install injection tubes.
Flare nut:
: 14-20N´m
(1.4 - 2.0 kg-m, 10 - 15 ft-lb)
5. Bleed air from fuel system.
