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, do the fuel pump circuit troubleshooting.
3.
Read the fuel pressure gauge. The pressure should be 395?405 kPa (4.03?4.13 kgf/cm2, 57.3?58.7 psi).
