which sensor? Everybody says crank sensor controls spark but my wiring diagram only shows Hall effect in distributor?

so I performed a test on my crank sensor, I have constant 5 volts in and constant 5 volts out, never a fluctuation In my meter whether cranking or bumping , I’m guessing this is telling me my crank sensor is bad? I get 12 volts to my coil still when I turn on the key but goes away as soon as I crank it.

so wanted to thank everybody for their help, and finish my thread out, after numerous trips to the parts store, and 2 months of aggravation, and only about $300 in parts, turns out the first part I bought, the crank sensor, was wrong, my 96 truck uses a 97 crank sensor, plug is different. But I’m happy, it’s runnong better than ever with all the new parts!😂 thanks again, till next time!!
