Test Description
Number(s) below refer to the step number(s) on the Diagnostic Chart.
2. Connect the fuel pressure gauge to the fuel feed line as shown in the fuel system illustration. Wrap a shop towel around the fuel pressure
connection in order to absorb any fuel leakage that may occur when installing the fuel pressure gauge. With the ignition switch "ON" and the fuel
pump running, the fuel pressure indicated by the fuel pressure gauge should be 333 - 376 kpa (48 - 55 psi). This pressure is controlled by the
amount of pressure the spring inside the fuel pressure regulator can provide.
3. A fuel system that cannot maintain a constant fuel pressure has a leak in one or more of the following areas:
-
The fuel pump check valve.
-
The fuel pump flex line.
-
The valve or valve seat within the fuel pressure regulator.
