2.3.7.7 Fuel Pressure Testing Procedure

Warning!

Gasoline and gasoline vapor is highly flammable. In order to avoid fire or explosion, please select keep away from a
fire. It is prohibited to use mobile phones during this procedure. Do not use open containers to store gasoline exhaust
emissions. Before carrying out this procedure, please prepare a dry-chemical fire extinguisher.

Warning!

Wrap a cloth around the fuel pressure gage and fuel rail joints to absorb leaked fuel when you connect the fuel pressure
gage to reduce the risk of fire and injury. Upon completion of testing, place the cloth into the designated containers.
Clean pipe joints before removal.

Warning!

It is prohibited to pour or store fuel in an open container, otherwise it will cause a fire.

Step 1

Install fuel pressure gage in the fuel rail intake.

Next

Step 2

Place the fuel pressure gage exhaust hose into a specified gasoline container.

Next

Step 3

Open the valve on the fuel pressure gage to discharge the air from the gage.

Next

Step 4

Turn the ignition switch to "ON" position.

Next

Step 5

Use scan tool "Function Test" drive fuel pump fuel pump relay, until all the air expelled from pressure gage.

Next

Step 6

Turn off the exhaust valve on the fuel pressure gage.

Next

Step 7

Use scan tool to connect the fuel pump to check whether there is fuel leakage and the leakage location.

Next

Step 8

When there is no leakage in the pipeline, start the engine and the fuel pressure should be 400 kPa (58.01
psi).

Next

Step 9

Turn the ignition switch to "OFF" position. under normal circumstances the system should maintain residual
pressure above 250 kPa (36.26 psi). If the fuel pressure continues to drop, check the fuel pump or fuel
pressure regulator.

2.3.8 Removal and Installation
2.3.8.1 Fuel Pressure Release Procedure

FE02-0066b

1.

Open the fuel tank cap.

2.

Open the hood, pull out fuel pump fuse EF05 (15 A).

3.

Start  the  engine  until  the  engine  stops  running
automatically.

4.

Start the engine again, so that the crankshaft continues to
rotate about 10 s.

Note

If you want to remove any fuel system components,
wrap  pipe  joints  with  plastic  bags  to  prevent  fuel
leakage and prevent the entry of foreign matter.

FE02-0068b

5.

Loosen filter retaining bolts on the bracket.

6.

Disconnect the fuel inlet and outlet pipes.

Note

If  sand  enters  into  the  pipe  joints,  removal  may
become difficult. With a wood handle gently knock
the filter housing to remove the sand, and then push
the pipe toward the filter direction. Press the lock to
Disconnect the pipe.

Installation Procedure:

FE02-0069b

1.

Install the fuel filter to the bracket and pay attention to the
direction of the filter.

2.

Connect the fuel inlet and outlet pipes.

3.

Tighten the filter retaining bolts.

4.

Install fuel filter bracket bolts.

Torque: 9 Nm (Metric) 6.66 lb-ft (US English)

5.

Connect the battery negative cable.
