Flammable - Keep Fire Away

NOTE:

2. Fuel Hose Cover - Remove

3. Fuel Line - Disconnect

2.
Check the fuel quick-connect fitting (B) for dirt, and clean it if needed.
3.
Place a rag or shop towel over the quick-connect fitting, then disconnect the quick-connect fitting.

4. Fuel Pressure - Test

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.
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:

Grade name
Standard value
Except Si
390?440 kPa (3.98?4.49 kgf/cm2, 56.6?63.8 psi)
Si
400?450 kPa (4.08?4.59 kgf/cm2, 58.0?65.3 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.
