Fuel Pressure

2013 Chevrolet Cruze L4-1.8LSECTION Fuel Pressure




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.



Ignition ON, engine OFF, command the Fuel Pump Enable On several times with a scan tool.
Verify the fuel pressure is between 345-650 kPa (50-94 psi) with the fuel pump running.
