3 - Fuel Flow/Pressure Tests
WARNING: This page is about a different car, the 2002 Saturn LW300 and 2002 Saturn L300. However, it is still accessible from the selected car via links, so may be relevant.
These tests will determine whether the fuel system can supply adequate volume of fuel at the desired pressure to operate the engine under full load conditions. The test is done at four points in the system to isolate and identify the problem component: fuel pump, fuel filter, fuel injectors/rail, or fuel supply line.
