FUEL PUMP CIRCUIT
Revision: 2005 July 2005 FX
FUEL PUMP CIRCUITPFP:17042
DescriptionABS007X1
SYSTEM DESCRIPTION
*: ECM determines the start signal status by the signals of engine speed and battery voltage.
The ECM activates the fuel pump for several seconds after the ignition switch is turned ON to improve engine
startability. If the ECM receives a engine speed signal from the camshaft position sensor (PHASE), it knows
that the engine is rotating, and causes the pump to operate. If the engine speed signal is not received when
the ignition switch is ON, the engine stalls. The ECM stops pump operation and prevents battery discharging,
thereby improving safety. The ECM does not directly drive the fuel pump. It controls the ON/OFF fuel pump
relay, which in turn controls the fuel pump.
COMPONENT DESCRIPTION
A turbine type design fuel pump is used in the fuel tank.

Precautions Necessary for Steering Wheel Rotation After Battery DisconnectABS00B3J
NOTE:

This Procedure is applied only to models with Intelligent Key system and NVIS/IVIS (NISSAN/INFINITI
VEHICLE IMMOBILIZER SYSTEM - NATS).

Remove and install all control units after disconnecting both battery cables with the ignition knob in the
″ LOCK ″ position.

Always use CONSULT-II to perform self-diagnosis as a part of each function inspection after finishing
work. If DTC is detected, perform trouble diagnosis according to self-diagnostic results.
For models equipped with the Intelligent Key system and NVIS/IVIS, an electrically controlled steering lock
mechanism is adopted on the key cylinder.
For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and
steering wheel rotation will become impossible.
If steering wheel rotation is required when battery power is interrupted, follow the procedure below before
starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.
2. Use the Intelligent Key or mechanical key to turn the ignition switch to the ″ACC ″ position. At this time, the
steering lock will be released.
3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be rotated.
4. Perform the necessary repair operation.
5. When the repair work is completed, return the ignition switch to the ″LOCK ″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of all control units using CONSULT-II.
Precautions for Drain Engine Coolant and Engine OilABS00E3J
Drain engine coolant and engine oil when the engine is cooled.
Precautions for Disconnecting Fuel PipingABS00E3K

Before starting work, make sure no fire or spark producing items are in the work area.

Release fuel pressure before disconnecting and disassembly.

After disconnecting pipes, plug openings to stop fuel leakage.
Precautions for Removal and DisassemblyABS00E3L

When instructed to use SST, use specified tools. Always be careful to work safely, avoid forceful or unin-
structed operations.

Exercise maximum care to avoid damage to mating or sliding surfaces.

Dowel pins are used for several parts alignment. When replacing and reassembling parts with dowel pins,
make sure that dowel pins are installed in the original position.

Cover openings of engine system with a tape or equivalent, if necessary, to seal out foreign materials.

Mark and arrange disassembly parts in an organized way for easy troubleshooting and re-assembly.

When loosening nuts and bolts, as a basic rule, start with the one furthest outside, then the one diagonally
opposite, and so on. If the order of loosening is specified, do exactly as specified. Power tools may be
used in the step.
Precautions for Inspection, Repair and ReplacementABS00E3M
Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.

the figure.
Use Genuine RTV Silicone Sealant or equivalent. Refer to
GI-48, "
RECOMMENDED CHEMICAL PRODUCTS AND
SEALANTS" .
CAUTION:
Attaching should be done within 5 minutes after coating.
c. Install oil pan (lower).

Tighten mounting bolts in numerical order as shown in the fig-
ure.
5. Install oil pan drain plug.

Refer to the figure of components of former page for installation direction of drain plug washer. Refer to
EM-35, "
Components (AWD Model)" .
6. Install in the reverse order of removal after this step.
NOTE:
At least 30 minutes after oil pan is installed, pour engine oil.
INSPECTION AFTER INSTALLATION
1. Check the engine oil level and adjust engine oil. Refer to LU-7, "ENGINE OIL" .
2. Start engine, and check there is no leak of engine oil.
3. Stop engine and wait for 10 minutes.
4. Check the engine oil level again. Refer to LU-7, "
ENGINE OIL" .

INSPECTION AFTER INSTALLATION
Inspection of Camshaft Sprocket (INT) Oil Groove
CAUTION:

Perform this inspection only when DTC P0011 or P0021 are detected in self-diagnostic results of
CONSULT-II and it is directed according to inspection procedure of EC section. Refer to EC-136,
"SELF-DIAG RESULTS MODE" .

Check when engine ins cold so as to prevent burns from any splashing engine oil.
1. Check the engine oil level. Refer to LU-7, "
ENGINE OIL" .
2. Perform the following procedure so as to prevent the engine from being unintentionally started while checking.
a. Release fuel pressure. Refer to EC-99, "
FUEL PRESSURE RELEASE" .
b. Disconnect ignition coil and injector harness connectors.
3. Remove intake valve timing control solenoid valve. Refer to EM-84, "
CAMSHAFT" .
4. Crank the engine, and then make sure that engine oil comes out from camshaft bracket (No. 1) oil hole. End crank after checking.
WARNING:
Be careful not to touch rotating parts (drive belts, idler pul-
ley, and crankshaft pulley, etc.).
CAUTION:
Engine oil may squirt from intake valve timing control sole-
noid valve installation hole during cranking. Use a shop
cloth to prevent the engine components and the vehicle. Do
not allow engine oil to get on rubber components such as
drive belt or engine mount insulators. Immediately wipe off
any splashed engine oil.

Clean oil groove between oil strainer and intake valve timing control solenoid valve if engine oil does not
come out from camshaft bracket (No. 1) oil hole. Refer to LU-5, "
LUBRICATION SYSTEM" .
5. Remove components between intake valve timing control solenoid valve and camshaft sprocket (INT), and then check each oil groove for clogging.

Clean oil groove if necessary. Refer to LU-5, "LUBRICATION SYSTEM" .
6. After inspection, install removed parts.
Inspection for Leaks
The following are procedures for checking fluids leak, lubricates leak.

Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-12, "
RECOMMENDED FLUIDS AND LUBRICANTS" .

Use procedure below to check for fuel leakage.
–Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel
leakage at connection points.
–Start engine. With engine speed increased, check again for fuel leakage at connection points.

Run engine to check for unusual noise and vibration.
NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal/installation, slack in the guide may
generate a pounding noise during and just after engine start. However, this is normal. Noise will stop after
hydraulic pressure rises.

Warm up engine thoroughly to make sure there is no leakage of fuel, or any oil/fluids including engine oil
and engine coolant.

Bleed air from lines and hoses of applicable lines, such as in cooling system.

After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the
specified level, if necessary.

When installing engine mounting bracket (RH and LH) on cylin-
der block, tighten two upper bolts (shown as “A” in the figure)
first. Then tighten two lower bolts (shown as “B” in the figure).
