Fuel Pressure Hold Inspection
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" on page F2-106.
Fuel Pressure Hold Inspection
- 1Disconnect the negative battery cable.
- 2Install a fuel pressure gauge as shown in the figure.
- 3Connect the negative battery cable.
- 4Connect the data link connector terminals F/P and GND by using a jumper wire.
- 5Turn the ignition switch to ON for 10 sec. to operate the fuel pump.
- 6Turn the ignition switch to OFF and disconnect the jumper wire.
- 7Observe the fuel pressure after 5 min.
- 8If not as specified, perform the following inspections: Fuel pump hold pressure (Refer to page F2-111.); Pressure regulator hold pressure (Refer to page F2-114.); Fuel injector fuel leakage (Refer to page F2-116.)
| Specification | Value |
|---|---|
| Fuel pressureafter 5 min hold | More than 150kPa {1.5 kgf/cm2, 21 psi} |
Fuel pressureafter 5 min hold
More than 150kPa {1.5 kgf/cm2, 21 psi}
Fuel Line Pressure Inspection
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" on page F2-106.
Fuel Line Pressure Inspection

- 2Install a fuel pressure gauge as shown in the figure.
- 3Connect the negative battery cable.
- 4Connect data link connector terminals F/P and GND by using a jumper wire.
- 5Turn the ignition switch to ON.
- 6Measure the fuel line pressure.
| Specification | Value |
|---|---|
| Fuel line pressure | 260-310kPa {2.6-3.2 kgf/cm2, 37-45 psi} |
Fuel line pressure
260-310kPa {2.6-3.2 kgf/cm2, 37-45 psi}
Fuel line pressure out of specification
Pressure low
ActionMeasure fuel pump maximum pressure. (Refer to Page F2-110.) If as specified, the fuel line or fuel filter might be clogged or restricted.
Pressure high
ActionReplace the pressure regulator.
