Fuel System

Warning: Fuel line spills and leaks are dangerous. Fuel can ignite and cause serious injuries or death and damage. Fuel can also irritate skin and eyes. To prevent this, always complete the "Fuel Line Safety Procedures" above.

Hold Inspection
1. Disconnect the negative battery terminal.




2. Install a fuel pressure gauge between the fuel filter and the main fuel hose. (Install clamps as shown.)
3. Connect the negative battery terminal.




4. Connect the data link connector terminals F/P and GND with a jumper wire.
5. Turn the ignition switch ON for 10 sec. to operate the fuel pump.
6. Turn the ignition switch OFF and disconnect the jumper wire.
7. Observe the fuel pressure after 5 min.

Fuel pressure: More than 150 kPa (21 psi)

8. If not as specified, perform the following inspections.
- Fuel pump hold pressure.
- Pressure regulator hold pressure.
- Injector fuel leakage.

Fuel Line Pressure Inspection
1. Disconnect the negative battery cable.




2. Install a fuel pressure gauge between the fuel filter and the main fuel hose. (Install clamps as shown.)
3. Connect the negative battery cable.




4. Connect data link connector terminals F/P and GND with a jumper wire.
5. Turn the ignition switch ON.
6. Measure the fuel line pressure.

Fuel line pressure: 260-320 kPa (37-46 psi)

7. If not as specified, perform the following inspections.
- Fuel pump maximum pressure.
- Fuel line clogging and restriction.
- Fuel filter clogging and restriction.
- Pressure regulator hold pressure.
