BASIC SERVICE PROCEDURE

2. Perform “FUEL PRESSURE RELEASE” in “WORK SUPPORT”
mode with CONSULT-II.
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-II
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
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 J31 models do not have fuel return system.
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 sealability with O-rings inside.

When installing fuel hose quick connector, refer to EM-19, "INTAKE MANIFOLD" .
1. Release fuel pressure to zero. Refer to EC-49, "
FUEL PRESSURE RELEASE" .
2. Prepare fuel hose and fuel hose clamp 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.

Do not use the fuel hose for checking fuel pressure with damage or cracks on it.

Use Pressure Gauge to check fuel pressure.
3. Remove fuel hose. Refer to EM-19, "
INTAKE MANIFOLD" .

Do not twist or kink fuel hose because it is plastic hose.

Do not 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.

Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
