Default No spark on 1996 Dodge Ram 1500

hello! Seen a lot of posts about this and none have helped me so figured I would try my own. 96 ram 1500 4x4, drove home one night fine, won’t start next day. Found “engine” fuse blown, replaced it, still cranks, getting fuel, won’t start. Sooo, I have now replaced crank sensor, cam sensor, cap and rotor, ecm and coil, still same condition, I’ve redone my grounds, when checking voltages at ecm I’ve got my twelve volts and five colts out, but don’t have 5 volts to distributor, and I have 12 volts at coil until I crank it then drops to nothing. My wiring diagram shows I should have an orange wire for 5 volts to distributor, and although it ohms out it is a blue wire , not orange at distributor. I’ve unplugged and cleaned all of my wire plugs and junctions. At this point I’m stumped! Any ideas would be greatly appreciated! Thanks in advance for any assistance !

An engine needs 5 things to start see what your are missing
1. Air
2. Fuel
3. Spark
4. Compression
5. Timing

I’ve tried a few ways, put a plug in plug wire, arcing coil wire to exhaust manifold and put plug in coil wire

What brand crank sensor did you get? Was it for the correct style trans? (yes, there IS a difference between auto, and manual sensors.)

I have 12 volts at coil until I crank it then drops to nothing.
What condition is the battery in? Check engine light on? If so you can get codes here...

Battery is new, I replaced battery cables, still nothing, removed distributor cap and made sure it’s turning, verified 5 volts to distributor, coil still has 12 volts when you turn on key, drops to nothing while cranking, back to 12 when you stop cranking, anybody have any ideas what this means? Truck only throws one code, 1765, which shows no 12 v to trans sensor, I clear that code, crank and it’s back, no check engine either.
