Here are the directions specific to your vehicle for testing fuel pressure. The manufacturer's specs are listed in the directions. The attached pic shows location to attach fuel pressure gauge.

Fuel Pressure Test
Special Tools Required
- Fuel pressure gauge 07406-004000B
- Fuel pressure gauge attachment set 07AAJ-S6MA150
1. Relieve the fuel pressure.
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.
5. Read the fuel pressure gauge. The pressure should be 390 - 440 kPa (4.0 - 4.5 kgf/sq. Cm, 57 - 64 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, then recheck the fuel pressure.
Let me know what you find.
