Fuel Pressure

2011 Chevrolet Traverse FWD V6-3.6LSECTION Fuel Pressure



Fuel pressure

Ignition ON, engine OFF 345-690 kPa (50-100 psi)

Engine idling at normal operating temperature 300-400 kpa (43-58 psi)


Relieve the fuel pressure to 69 kPa (10 psi). Verify that the fuel pressure does not decrease greater than 14 kPa (2 psi) in 5 min


Note: DO NOT perform the Fuel System Diagnosis if the engine coolant temperature is above 60°C (150°F). High fuel pressure readings may result due to hot soak fuel boiling. With the engine OFF, the fuel pressure may increase beyond the pressure relief regulator valve's setting point of 690 kPa (100 psi) ± 5 percent.
