#### Fuel Pressure Test

11-431

Special Tools Required

- Fuel pressure gauge 07406-0040002
- Fuel pressure gauge set 07ZAJ-S5A0100

1. Relieve the fuel pressure (see page 11-430).
2. Disconnect the quick-connect fitting (A). Attach the fuel pressure gauge set and fuel pressure gauge.

3. Start the engine and let it idle.

- If the engine starts, go to step 5.
- If the engine does not start, go to step 4.

4. Check to see if the fuel pump is running: listen to the fuel fill port with the fuel fill cap removed. The fuel pump should run for 2 seconds when the ignition switch is first turned on.

- If the pump runs, step 5.
- If the pump does not run, perform the fuel pump circuit troubleshooting (see page 11-427).

5. Read the pressure gauge. The pressure should be 270-320 kpa (2.8-3.3 kgf/cm2, 40-47 psi)

- If the pressure is OK, the test is complete.
- If the pressure is out of specification, replace the fuel pressure regulator and the fuel filter (see page 11-438), and recheck the fuel pressure.
