• As a guide, if the fuel tank is full the fuel leve
l reaches or is less than the level on the fuel gauge as
shown, when approximately 34 (9 US gal, 7 1/2 Imp gal) of fuel is drained from a full fuel tank.
3. Open the fuel filler cap to release the pressure inside the fuel tank.
4. Release fuel pressure from fuel line. Refer to EC-182, "Work Procedure"
(QR25DE), EC-687, "Work Pro-
cedure" (VQ35DE).
5. Remove rear seat cushion. Refer to SE-36, "Removal and Installation - Seat Assembly"
.
6. Turn the four retainers (A) 90 ° in a clockwise direction and
remove the fuel pump inspection hole cover.
7. Disconnect the fuel level sensor, fuel filter, and fuel pump assembly harness connector (C), EVAP hose quick connector
(A), and fuel feed hose (B) quick connector.
a. Disconnect the quick connectors as follows: • Hold the sides of the connector, push in tabs and pull out the
tube.
• If the connector and the tube are stuck together, push and pull
several times until they start to move. Then disconnect them
by pulling.
CAUTION:
• The tube can be removed when the tabs are completely depressed. Do not twist it more than necessary.
• Do not use any tools to remove the quick connector.
• Keep the resin tube away from heat. Be especially careful
when welding near the tube.
• Prevent acid liquid such as battery elect rolyte, from getting on the resin tube.
• Do not bend or twist the tube during installation and removal.
• Only when the tube is replaced, remove the remaining retainer on the tube or fuel level sensor,
fuel filter, and fuel pump assembly.
• When the tube or fuel level sen sor, fuel filter, and fuel pump assembly is replaced, also replace
the retainer with a new one (green colored retainer).
• To keep the connecting portio n clean and to avoid dam-
age and foreign materials, cover them completely with
plastic bags or something similar.

Inspection and AdjustmentINFOID:0000000009460626
INSPECTION
Make sure the mounting conditions (looseness, back lash) of each component and component conditions
(wear, damage) are normal.
LOWER BALL JOINT END PLAY
1. Set front wheels in a straight-ahead position. Do not depress brake pedal.
2. Place an iron bar or similar tool between upper link and steering knuckle.
3. Measure axial end play by prying it up and down.Refer to FSU-26, "Ball Joint"
.
CAUTION:
Be careful not to damage ball joint boot. Do not damage the installation position by applying
excessive force.
SHOCK ABSORBER
Check for oil leakage, damage and repl ace if malfunction is detected.
WHEEL ALIGNMENT
Description
Measure wheel alignment under unladen conditions.
NOTE:
"Unladen conditions" means that fuel, engine coolant, and lubricant are full. Spare tire, jack, hand tools and
mats are in designated positions.
General Information and Recommendations
• A four-wheel thrust alignment should be performed.
- This type of alignment is re commended for any NISSAN vehicle.
- The four-wheel "thrust" process helps ensure that t he vehicle is properly aligned and the steering wheel is
centered.
- The alignment rack itself should be capable of accepting any NISSAN vehicle.
- The rack should be checked to ensure that it is level.
• Make sure the machine is properly calibrated.
- Your alignment equipment should be regularly ca librated in order to give correct information.
- Check with the manufacturer of your specific equi pment for their recommended Service/Calibration Sched-
ule.
Preliminary Check
Check the following:
1. Tires for improper air pressure and wear.
2. Road wheels for runout. Refer to WT-60, "Road Wheel"
.
3. Wheel bearing axial end play. Refer to FAX-27, "Wheel Bearing"
.
4. Transverse link ball joint axial end play. Refer to FSU-11, "Removal and Installation"
.
5. Shock absorber operation.
6. Each mounting part of axle and suspension for looseness and deformation.
7. Each of suspension member, shock absorber, upper link and transverse link for cracks, deformation and other damage.
8. Vehicle height (posture).
Alignment Process
IMPORTANT:
Use only the alignment specificati ons listed in this Service Manual.
• When displaying the alignment settings, m any alignment machines use "indicators" Do not use these indi-
cators. : (Green/red, plus or minus, Go/No Go).
- The alignment specifications programmed into your machine that operate these indicators may not be cor-
rect.

To prevent ECM from storing the diagnostic trou ble codes, do not carelessly disconnect the harness
connectors which are related to the engine cont rol system and TCM (transmission control module)
system. The connectors should be disconnected only when working according to the WORK FLOW of
TROUBLE DIAGNOSES in EC and TM sections.
Three Way CatalystINFOID:0000000009462996
If a large amount of unburned fuel flows into the catalyst , the catalyst temperature will be excessively high. To
prevent this, follow the instructions.
• Use unleaded gasoline only. Leaded gasoline will seriously damage the three way catalyst.
• When checking for ignition spark or measuring engine compression, make tests quickly and only when nec- essary.
• Do 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.
Fuel (Regular Unleaded Ga soline Recommended) QR25DEINFOID:0000000009462997
Use unleaded regular gasoline with an octane rating of at least 87 AKI (Anti-Knock Index) number (Research
octane number 91). E-85 fuel (85% fuel ethanol, 15% unl eaded gasoline) may only be used in vehicles specif-
ically designed for E-85 fuel (i.e. Flexible Fuel Vehicle - FFV models).
CAUTION:
Do not use leaded gasoli ne. Using leaded gasoline will damage the three way catalyst. Do not use E-85
fuel (85% fuel ethanol, 15% unlead ed gasoline) unless the vehicle is specifically designed for E-85 fuel
(i.e. Flexible Fuel Vehicle - FFV models). Using a fu el other than that specified could adversely affect
the emission control devices and systems, and could also affect the warranty coverage validity.
Fuel (Regular Unleaded Gasoline Recommended) VQ35DEINFOID:0000000009462998
Use unleaded regular gasoline with an octane rating of at least 87 AKI (Anti-Knock Index) number (Research
octane number 91). E-85 fuel (85% fuel ethanol, 15% unl eaded gasoline) may only be used in vehicles specif-
ically designed for E-85 fuel (i.e. Flexible Fuel Vehicle - FFV models).
CAUTION:
Do not use leaded gasoli ne. Using leaded gasoline will damage the three way catalyst. Do not use E-85
fuel (85% fuel ethanol, 15% unlead ed gasoline) unless the vehicle is specifically designed for E-85 fuel
(i.e. Flexible Fuel Vehicle - FFV models). Using a fu el other than that specified could adversely affect
the emission control devices and systems, and could also affect the warranty coverage validity.
Multiport Fuel Injection System or Engine Control SystemINFOID:0000000009462999
• Before connecting or disconnecti ng any harness connector for the
multiport fuel injection system or ECM:
Turn ignition switch to “OFF” position.
Disconnect negative battery terminal.
Otherwise, there may be damage to ECM.
• Before disconnecting pressurized fuel line from fuel pump to injec-
tors, be sure to release fuel pressure.
• Be careful not to jar components such as ECM and mass air flow sensor.
