Special Tools Required 

• Fuel Pressure Gauge 07408-004000B
• Fuel Pressure Gauge Attachment Set 07AAJ-S8MA150

1. Relieve the fuel pressure .
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 to ON (II) or engine start/stop button to select the ON mode.
   • If the pump runs, go to step 5,
   • If the pump does not run, do the fuel pump circuit troubleshooting .
5. Read the fuel pressure gauge.

   Fuel pressure should be: 390- 440 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 , with SH-AWD  and the fuel filter; without SH-AWD , with SH-AWD , then recheck the fuel pressure.
