ON-VEHICLE MAINTENANCE
FUEL PRESSURE
Fuel Pressure Check
INFOID:0000000005273446
FUEL PRESSURE RELEASE
With CONSULT-III
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 two or three times to release all fuel pressure.
5.
Turn ignition switch OFF.
Without CONSULT-III
1.
Remove fuel pump fuse located in IPDM E/R.
2.
Start engine.
3.
After engine stalls, crank it two or three 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 pres-
sure cannot be completely released because D40 models do not have fuel return system.
Method A
CAUTION:
• The fuel hose connection method used when taking fuel pressure check must not be used for other
purposes.
• Be careful not to scratch or put debris around connection area when servicing, so that the quick
connector maintains seal ability with O-rings inside.
• Never perform fuel pressure check with electrical systems operating (i.e. lights, A/C, etc.) Fuel pres-
sure gauge may indicate false readings due to varying engine load and changes in manifold vacuum.
1.
Release fuel pressure to zero. Refer to "FUEL PRESSURE RELEASE".
2.
Prepare fuel hose for fuel pressure check, and connect fuel pressure gauge.
• Use suitable fuel hose for fuel pressure check (genuine NISSAN fuel hose without quick connector).
• To avoid unnecessary force or tension to hose, use moderately long fuel hose for fuel pressure check.
• Never use the fuel hose for checking fuel pressure with damage or cracks on it.
• Use Pressure Gauge to check fuel pressure.
3.
EM-27, "Removal and Installation"
.
• Never twist or kink fuel hose because it is plastic hose.
• Never remove fuel hose from quick connector.
• Keep the original fuel hose to be free from intrusion of dust or foreign substances with a suitable cover.
