Nissan Altima (L32) 2007-2012 Service Manual: Fuel pressure
Inspection
FUEL PRESSURE RELEASE
1. Turn ignition switch ON.
2. Perform “FUEL PRESSURE RELEASE” in “WORK SUPPORT” mode with CONSULT-III.
3. Start engine.
4. After engine stalls, crank it 2 or 3 times to release all fuel pressure.
5. Turn ignition switch OFF.
1. Remove fuel pump fuse (2) located in IPDM E/R (1).
2. Start engine.
3. After engine stalls, crank it 2 or 3 times to release all fuel pressure.
4. Turn ignition switch OFF.
5. Reinstall fuel pump fuse after servicing fuel system.
FUEL PRESSURE CHECK
CAUTION: Before disconnecting fuel line, release fuel pressure from fuel line to eliminate danger.
NOTE: • Prepare pans or saucers under the disconnected fuel line because the fuel may spill out. The fuel pressure cannot be completely released because L32 models do not have fuel return system.
• Be careful not to scratch or get the fuel hose connection area dirty when servicing, so that the quick connector o-ring maintains seal ability.
• Use Fuel Pressure Gauge Kit [SST (J-44321)] and Fuel Pressure Adapter [SST (J-44321-6)] to check fuel pressure.
1. Release fuel pressure to zero.
2. Remove fuel hose using Quick Connector Release [SST (J-45488)].
• Do not twist or kink fuel hose because it is plastic hose.
• Do not remove fuel hose from quick connector.
• Keep fuel hose connections clean.
3. Install Fuel Pressure Adapter [SST (J-44321-6)] and Fuel Pressure Gauge kit [SST (J44321)] as shown in figure.
• Do not distort or bend fuel rail tube when installing fuel pressure gauge adapter.
• When reconnecting fuel hose, check the original fuel hose for damage and abnormality.
4. Turn ignition switch ON (reactivate fuel pump) and check for fuel leakage.
5. Start engine and check for fuel leakage.
6. Read the indication of fuel pressure gauge kit [SST (J-44321)].
• During fuel pressure check, check for fuel leakage from fuel connection every 3 minutes.
At idling : Approximately 350 kPa (3.57 kg/cm2, 51 psi)
7. If result is unsatisfactory, go to next step.
8. Check the following.
• Fuel hoses and fuel tubes for clogging
• Fuel filter for clogging
• Fuel pump
• Fuel pressure regulator for clogging
9. If OK, replace fuel pressure regulator.
If NG, repair or replace malfunctioning part.
10. Before disconnecting Fuel Pressure Gauge kit [SST (J-44321)] and Fuel Pressure Adapter [SST (J- 44321-6)], release fuel pressure to zero.
Evap leak check
Inspection
CAUTION:
• Never use compressed air or a high pressure pump.
• Never exceed 4.12 kPa (0.042 kg/cm2, 0.6 psi) of pressure in EVAP system.
NOTE:
• Do not start engine.
• I ...
