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. 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 (II) or engine start/stop button to select the ON mode
   • If the pump runs, go to step 5
   • '09 model without SH-AWD, '10 - 11 model: If the pump does not run, do the fuel pump circuit troubleshooting (see FUEL PUMP CIRCUIT TROUBLESHOOTING )
   • '09 model with SH-AWD, If the pump does not run, refer to the DTC TROUBLESHOOTING 
5. Read the fuel pressure gauge

   Fuel pressure should be. 

   392-441 kPa (4.0-4.5 kgf/cm ²  , 57-64 psi) 

   • If the pressure is OK, the test is complete
   • If the pressure is out of specification, replace the fuel pressure regulator, without SH-AWD system (see FUEL PRESSURE REGULATOR REPLACEMENT ), with SH-AWD system (see FUEL PRESSURE REGULATOR REPLACEMENT ) and the fuel filter, without SH-AWD system (see FUEL FILTER REPLACEMENT ), with SH-AWD system (see FUEL FILTER REPLACEMENT ), then recheck the fuel pressure
