Fuel Pressure CheckUBS00QOB
FUEL PRESSURE RELEASE
With CONSULT-II
1. Turn ignition switch ON.
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 (1) located in IPDM E/R (2).

: Vehicle front
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
pressure cannot be completely released because C11 models do not have fuel return system.

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.

Do not perform fuel pressure check with electrical systems operating (i.e. lights, rear defogger, A/
C, etc.) Fuel pressure gauge may indicate false readings due to varying engine load and changes
in manifold vacuum.
1. Release fuel pressure to zero. Refer to EC-81, "
FUEL PRESSURE RELEASE" .
2. Prepare fuel hose for fuel pressure check B and fuel tube
adapter (KV10118400) D, then connect fuel pressure gauge A.

: To quick connector

: To fuel tube (engine side)

C: Clamp

Use suitable fuel hose for fuel pressure check (genuine NIS-
SAN fuel hose without quick connector).

To avoid unnecessary force or tension to hose, use moder-
ately long fuel hose for fuel pressure check.

Do not use the fuel hose for checking fuel pressure with dam-
age or cracks on it.

Use Pressure Gauge to check fuel pressure.
3. Remove fuel hose. Refer to EM-18, "
INTAKE MANIFOLD" .

19. Fully lift up lever (A), and push the slack guide (B) into the inside
of chain tensioner (for oil pump) (1).

The slack guide is released by fully lifting the lever up. As the
result, the slack guide can be moved.
20. Matching the hole on lever with the hole on tensioner body,
insert a stopper pin (C) to secure slack guide.
NOTE:
Use approximately 1.0 mm (0.04 in) diameter. hard metal pin as
a stopper pin.
21. Remove chain tensioner (for oil pump).

When the holes on lever and tensioner body cannot be aligned, align these holes by slightly moving the
slack guide.
22. Hold the WAF part of oil pump shaft (A), and then loosen the oil pump sprocket bolt and remove them.
CAUTION:

Secure the oil pump shaft with the WAF part.

Never loosen the oil pump sprocket bolt by tightening the
oil pump drive chain.
23. Remove crankshaft sprocket, oil pump sprocket and oil pump drive chain as a set.
24. Remove timing chain tension guide (front cover side) from front cover if necessary.
INSPECTION AFTER REMOVAL
Timing Chain

Check timing chain and oil pump drive chain for cracks (A) and
any excessive wear (B) at the roller links of timing chain.

SERVICE INFORMATION FOR ELECTRICAL INCIDENT
Revision: June 20062007 Versa

Freezing

Water intrusion

Electrical load

Cold or hot start up
Get a thorough description of the incident from the customer. It is important for simulating the conditions of the
problem.
Vehicle Vibration
The problem may occur or become worse while driving on a rough road or when engine is vibrating (idle with
A/C on). In such a case, you will want to check for a vibration related condition. Refer to the following illustra-
tion.
CONNECTORS & HARNESS
Determine which connectors and wiring harness would affect the electrical system you are inspecting. Gently
shake each connector and harness while monitoring the system for the incident you are trying to duplicate.
This test may indicate a loose or poor electrical connection.
HINT
Connectors can be exposed to moisture. It is possible to get a thin film of corrosion on the connector termi-
nals. A visual inspection may not reveal this without disconnecting the connector. If the problem occurs inter-
mittently, perhaps the problem is caused by corrosion. It is a good idea to disconnect, inspect and clean the
terminals on related connectors in the system.
SENSORS & RELAYS
Gently apply a slight vibration to sensors and relays in the system you are inspecting.
This test may indicate a loose or poorly mounted sensor or relay.
ENGINE COMPARTMENT
There are several reasons a vehicle or engine vibration could cause an electrical complaint. Some of the
things to check for are:

Connectors not fully seated.

Wiring harness not long enough and is being stressed due to engine vibrations or rocking.

Wires laying across brackets or moving components.

Loose, dirty or corroded ground wires.

Wires routed too close to hot components.
To inspect components under the hood, start by verifying the integrity of ground connections. (Refer to Ground
Inspection described later.) First check that the system is properly grounded. Then check for loose connection
by gently shaking the wiring or components as previously explained. Using the wiring diagrams inspect the
wiring for continuity.
BEHIND THE INSTRUMENT PANEL
An improperly routed or improperly clamped harness can become pinched during accessory installation. Vehi-
cle vibration can aggravate a harness which is routed along a bracket or near a screw.
