Warning

•  Fuel vapor is hazardous. It can very easily ignite, causing serious injury and damage. Always keep sparks and flames away from fuel.

•  Highly pressurized fuel may spray out if the fuel line is cut. Due to the following dangers occurring with a fuel spray, always complete the “Fuel Line Safety Procedure” to prevent the fuel from spraying.

―  Fuel may cause irritation if it comes in contact with skin and eyes.

―  If fuel ignites and causes a fire, it may lead to serious injury or death, and damage to property and facilities.

•  A person charged with static electricity could cause a fire or explosion, resulting in death or serious injury. Before performing work on the fuel system, discharge static electricity by touching the vehicle body.

Caution

•  If foreign matter enters the fuel passage, it could cause serious damage to the fuel injection related parts. When removing/installing the fuel injection related parts, pay close attention so that foreign matter does not enter the fuel passage.

Fuel Line Safety Procedure

1.  Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION [(E)].)

2.  Remove the fuel-filler cap to release the pressure inside the fuel tank.

3.  Remove the fuel pump relay.


4.  Disconnect the high pressure fuel pump connector.

5.  Connect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION [(E)].)

6.  Start the engine.

7.  After the engine stalls, crank the engine 2—3 times.

8.  Switch the ignition to off.

9.  Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION [(E)].)

10.  Install the fuel pump relay.

11.  Connect the high pressure fuel pump connector.

Warning

•  Fuel line spills and leakage are dangerous. Fuel can ignite and cause serious injuries or death and damage. When installing the fuel hose, perform “Fuel Leakage Inspection” described below.

•  A person charged with static electricity could cause a fire or explosion, resulting in death or serious injury. Before performing work on the fuel system, discharge static electricity by touching the vehicle body.

Fuel Leakage Inspection

1.  Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION [(E)].)

2.  Remove the fuel pump relay.


Caution

•  Short the specified terminals because shorting the wrong terminal of the relay and fuse block may cause malfunctions.

3.  Using a jumper wire, short fuel pump relay terminals C and D in the relay and fuse block.


4.  Connect the negative battery terminal and operate the fuel pump. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION [(E)].)

5.  Verify that there is no fuel leakage from the serviced parts.

Standard

There shall be no leakage after 5 min.

6.  In the case of fuel leakage, replace the following components and then recheck using the fuel leakage checking procedure.

•  If there is leakage, replace the fuel hoses and clips.

•  If there is damage on the seal on the fuel pipe side, replace the fuel pipe.
