A little low, we’ll come back to that later. Now back probe cavity 1 gray wire with a black tracer and with the key on turn the engine over by hand and watch the DVOM for the reference signal changing from the reference signal voltage to zero and back to signal voltage. Turn the engine by hand slowly while watching the meter.

Until you see the voltage go from 5v to zero and back again. It’s using a series notches cut in the flywheel to switch on & off.
that’s okay, turn it in 1/4 inch increments. If the voltage never switches on & off, the crankshaft position sensor is bad.

Ok I am a dumb*ss. Forgot to plug the pcm connectors back in before I took the readings. With the PCM connectors back in and key on, I get an varying signal. 5 to 0

Lol, okay. Disconnect C104 connector at the firewall and check pin 11 for battery voltage while you have the ASD relay removed and jumper installed like you did earlier.
