Hi and thanks for using 2CarPros.com.
Many things can cause a no start. The first thing I need you to do is review the attached link. It discusses possible causes, how to check them, and how to repair. Do this first and let me know what you find.

The aforementioned link discusses checking fuel pump pressure in general. Here are the directions specific to your vehicle which include the manufacturer's specifications. The attached picture correlates with these directions.
_______________________
FUEL PRESSURE CHECK
CAUTION: Be careful not to scratch or get the fuel hose connection area dirty when servicing, so that the quick connector o-ring maintains sealability.
NOTE:
- Prepare pans or saucers under the disconnected fuel line because the fuel may spill out. The fuel pressure cannot be completely released because N50 models do not have fuel return system.
- Use Fuel Pressure Gauge Kit J-44321 and Fuel Pressure Gauge Adapter J-44321-6 to check fuel pressure.
1. Release fuel pressure to zero. Refer to "FUEL PRESSURE RELEASE".
2. Remove fuel hose using Quick Connector Release J-45488. Refer to "INTAKE MANIFOLD".
- Do not twist or kink fuel hose because it is plastic hose.
- Do not remove fuel hose from quick connector.
- Keep fuel hose connections clean.
3. Install Fuel Pressure Gauge Adapter J-44321-6 and Fuel Pressure Gauge44321) as shown in figure.
- Do not distort or bend fuel rail tube when installing fuel pressure gauge adapter.
- When reconnecting fuel hose, check the original fuel hose for damage and abnormality.
4. Turn ignition switch ON (reactivate fuel pump), and check for fuel leakage.
5. Start engine and check for fuel leakage.
6. Read the indication of fuel pressure gauge.
- During fuel pressure check, check for fuel leakage from fuel connection every 3 minutes.
At idling: Approximately 350 kPa (3.57 kg/sq.cm, 51 psi)
7. If result is unsatisfactory, go to next step.
8. Check the following.
- Fuel hoses and fuel tubes for clogging
- Fuel filter for clogging
- Fuel pump
- Fuel pressure regulator for clogging
If OK, replace fuel pressure regulator.
If NG, repair or replace.
9. Before disconnecting Fuel Pressure Gauge and Fuel Pressure Adapter, release fuel pressure to zero. Refer to "FUEL PRESSURE RELEASE".
