is there any way to test for a reference sensor?

you can test the reference sensor with an ohmmeter. the resistance should be 500-600ohms. i don't think that's gonna be your problem though.

you think if i pinched off my return fuel line i could effectively test my fuel pressure regulator?

(I don't have a fuel pressure tester)

Tested my o2 sensor. Got no voltage response at all. so i'm either really lean or the sensor isn't working. i even pinched off my return fuel line to try to force it to richen up.
