Fuel System Pressure Test
WARNING: This page is about a different car, the 2003 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
Install a Fuel Pressure Gauge (SA9127E) to fuel service test port. Turn ignition on, with engine off. Using a scan tool, command fuel pump on. Fuel pressure should be 50-60 psi (345-414 kPa). If fuel pressure is not as specified, diagnose fuel system.
