Fuel Pressure Test

Special Tools Required

Fuel pressure gauge 07406-004000B
Fuel pressure gauge attachment set 07AAJ-S6MA150
1. Relieve the fuel pressure (see FUEL PRESSURE RELIEVING ).
2. Disconnect the quick-connect fitting. Attach the fuel pressure gauge set and the 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 filler 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, go to step 5.
  - If the pump does not run, do the fuel pump circuit troubleshooting.
    - 2004-2005 models (see 2004-2005 MODELS )
    - 2006 model (see 2006 MODEL )
5. Read the fuel pressure gauge. The pressure should be 392-441 kPa (4.0-4.5 kgf/cm² , 57-64 psi).
  - If the pressure is OK, the test is complete.
  - If the pressure is out of specification, replace the fuel pressure regulator (see FUEL PRESSURE REGULATOR REPLACEMENT ) and the fuel filter (see FUEL FILTER REPLACEMENT ), then recheck the fuel pressure.
