Solution

1. Preparation

Gather necessary tools: fuel pressure gauge, safety glasses, gloves, and rags.
Ensure the vehicle is parked on a level surface, and the ignition is off.

2. Relieve Fuel System Pressure

Locate the fuel pump relay or fuse in the fuse box.
Remove the fuel pump relay or fuse to disable the fuel pump.
Start the engine and let it run until it stalls to relieve pressure, then turn off the ignition.

3. Connect Fuel Pressure Gauge

Remove the protective cap from the fuel pressure test port on the fuel rail.
Firmly attach the fuel pressure gauge to the Schrader valve, ensuring there are no leaks.

4. Test Fuel Pressure

Turn the ignition key to the "On" position without starting the engine.
Observe the pressure reading on the gauge; it should rise to the expected value.
If the pressure is low, perform additional checks such as inspecting the fuel pump and filter.

5. Disconnect the Gauge

Once testing is complete, safely disconnect the fuel pressure gauge.
Replace the protective cap on the fuel pressure test port.
Reinstall the fuel pump relay or fuse.
