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
   • If the pump runs, go to step 5
   • If the pump does not run, do the fuel pump circuit troubleshooting (see FUEL PUMP CIRCUIT TROUBLESHOOTING )
5. Read the fuel pressure gauge The pressure should be 330-380 kPa (3 4-3 9 kgf/cm² , 48-55 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 PRESSURE REGULATOR REPLACEMENT ), then recheck the fuel pressure
