I can assist you with that question. Unfortunately, Toyota did not provide a test port, you must tee into the fuel rail using an adapter.

The fuel pressure regulator is at the end of the fuel rail.

I am enclosing drawings for your convienience.graphicgraphic

Ed, my 1997 3.4L starts but sputters and stalls quickly. attempting to let out clutch stalls it for sure. I replaced fuel filter but problem persists. the odors from the exhaust smell like fuel. Perhaps, it is drowning in fuel, any suggestions?
