The book that I have says to test the fuel pressure at the fuel rail, But I can't find any test ports or stems on the rail. Am I looking in the wrong place? Is this test conclusive or should I test the pump again after removal.
 
There should be a Shrader valve located somewhere on the Fuel Rail possibly near the Fuel Pressure Regulator. It'll resemble the Valves on the A/C circuit.
The Shrader Valve is THE PORT where Test units are attached as well as relieving pressure for work on/with the Injectors.
