NOTE: If you were referred to this procedure from a troubleshooting procedure, test the fuel pressure under the same conditions the malfunction occurred (engine speed, load, throttle position, etc.).

1. Disconnect the quick-connect fitting

and attach the fuel pressure gauge set. Check for leaks with the gauge set attached.

2. Start the engine, and let it idle.

If the engine starts, go to step 3 and read the fuel pressure gauge.
If the pump does not run and any DTCs are stored, do the DTC troubleshooting .
If the pump does not run and no DTCs are stored, do the fuel pump circuit troubleshooting .

3. Read the fuel pressure gauge. The pressure should be: 410-460 kPa (4.18-4.69 kgf/cm 2, 59.5-66.7 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.
