1999 NISSAN PRIMERA fuel pressure

WARNING:
IPosition vehicle on a flat and solid surface.
IPlace chocks at front and back of rear wheels.
IDo not remove engine until exhaust system has com-
pletely cooled;
Otherwise, you may burn yourself and/or fire may break
out in fuel line.
IBefore disconnecting fuel hose, release fuel pressure
from fuel line.
Refer to ªReleasing Fuel Pressureº in EC section.
IBe sure to hoist engine and transaxle in a safe manner.
IFor engines not equipped with engine slingers, attach
slingers and bolts described in PARTS CATALOG.
CAUTION:
IWhen lifting engine, be sure to clear surrounding parts.
Use special care for accelerator cable, brake lines and
brake master cylinder.
IIn hoisting the engine, always use engine slingers in a
safe manner.
IWhen removing drive shaft, be careful not to damage
grease seal of transaxle.
Removal
1. Remove engine under cover and hood.
2. Drain coolant from both cylinder block, and radiator.
3. Drain engine oil.
4. Remove vacuum hoses, fuel hoses, wires, harness and con-
nectors.
5. Remove exhaust tubes, ball joints and drive shafts.
6. Remove radiator and fans.
7. Remove drive belts.
8. Remove alternator, compressor and power steering oil pump
from engine.
9. Set a suitable transmission jack under transaxle. Hoist engine
with engine slinger.
10. Remove center member.

WARNING:
When replacing fuel line parts, be sure to observe the following:
lDisplay a ªCAUTION: INFLAMMABLEº sign in workshop.
lDo not smoke while servicing fuel system. Keep open flames and sparks away from work area.
lBe sure to disconnect battery ground cable before conducting service operations.
lBe sure to furnish workshop with a CO2fire extinguisher.
lPour drained fuel into an explosion-proof container then ensure container lid is installed securely.
CAUTION:
lFor ECCS engine models, release fuel pressure from fuel line. Refer to EC section (ªFuel Pres-
sure Releaseº, ªBASIC SERVICE PROCEDUREº).
lDo not disconnect any fuel line unless absolutely necessary.
lPlug hose and pipe openings to prevent entry of dust or dirt.
lAlways replace top lid seal and hose clamps with new ones.
lDo not kink or twist hoses and tubes during installation.
lDo not tighten hose clamps excessively because this could cause damage to the hose.
lEnsure fuel check valve is installed in the correct orientation. Refer to EC section (ªFUEL CHECK
VALVEº, ªEVAPORATIVE EMISSION SYSTEMº).
lAfter installation, run engine and check for fuel leaks at connections.

Fuel Pump and Gauge
REMOVAL
1. Release fuel pressure from fuel line.
Refer to EC section (ªFuel Pressure Releaseº, ªBASIC SER-
VICE PROCEDUREº).
2. Remove inspection hole cover located under the rear seat.
3. Remove fuel filler lid.
4. Disconnect fuel outlet, return tube and connectors.
CAUTION:
Mark the fuel tubes to ensure correct position during instal-
lation.
5. Using SST KV999G0010, remove fuel gauge locking ring.
6. Lift the top plate from the fuel tank.
CAUTION:
lDo not disconnect fuel hoses from top plate. Top plate
has to be removed together with fuel chamber assy.
lFor CD20T models the fuel gauge sender unit is attached
to the top plate.
QG16DE, QG18DE & SR20DE models only:
7. Remove fuel pump with fuel tank chamber assy as follows:
a. Push the locking clip upwards and slide the pump chamber
assy towards the rear of the vehicle.
b. Lift the pump chamber assy from the bracket.
c. Carefully remove the pump chamber assy and top plate from
the tank.
CAUTION:
While removing the pump chamber assy lift the fuel gauge
sender float, to prevent it from bending.
8. Take off the fuel pump chamber lid by opening out the 4 clips.
Remove the fuel pump from the fuel pump chamber.
9. Remove the fuel gauge sender unit from the chamber by lift-
ing the clip and sliding the sender unit upwards.

Precautions for Multiport Fuel Injection
System or Engine Control Module
lBefore connecting or disconnecting any harness connector
for the multiport fuel injection system or ECM (Engine Con-
trol Module):
Turn ignition switch to ªLOCKº position.
Disconnect negative battery terminal.
Otherwise, there may be damage to ECM.
lBefore disconnecting pressurized fuel line from fuel pump to
injectors, be sure to release fuel pressure.
lBe careful not to jar components such as ECM and mass air
flow sensor.
Precautions for Three Way Catalyst
If a large amount of unburned fuel flows into the catalyst, the
catalyst temperature will be excessively high. To prevent this,
follow the instructions below:
lUse unleaded gasoline only. Leaded gasoline will seriously
damage the three way catalyst.
lWhen checking for ignition spark or measuring engine
compression, make tests quickly and only when necessary.
lDo not run engine when the fuel tank level is low, otherwise
the engine may misfire causing damage to the catalyst.
Do not place the vehicle on flammable material. Keep flammable
material off the exhaust pipe and the three way catalyst.
Precautions for Turbocharger
The turbocharger turbine revolves at extremely high speeds and
becomes very hot. Therefore, it is essential to maintain a clean
supply of oil flowing through the turbocharger and to follow all
required maintenance instructions and operating procedures.
lAlways use the recommended oil. Follow the instructions for
proper time to change the oil and proper oil level.
lAvoid accelerating engine to a high rpm immediately after
starting.
lIf engine had been operating at high rpm for an extended
period of time, let it idle for a few minutes prior to shutting it
off.
Precautions for Engine Oils
Prolonged and repeated contact with used engine oil may cause
skin cancer. Try to avoid direct skin contact with used oil.
If skin contact is made, wash thoroughly with soap or hand
cleaner as soon as possible.
HEALTH PROTECTION PRECAUTIONS
lAvoid prolonged and repeated contact with oils, particularly
used engine oils.
