Default 98 Durango no spark

I've got a 1998 Dodge Durango 5.2 4x4, best damn SUV I've ever owned, until now.

Was driving and the SUV shut off, after I had just replaced the IAC which fixed my idle issue. Now the vehicle has no spark going to the spark plugs (I assume) I've tried using an old spark plug and grounding it, I see no spark when someone else tries to start it.
The coil has spark. I've replaced the Plugs and wires, I put a brand new Distributor cap and rotor on to no avail. I feel like I'm running out of options, I don't know what else it could be. It is throwing no codes.

Check and see if the distributor is actually turning...

Verify you are getting spark TO the distributor.

It is turning and striking, I checked the Coil wire to the Distributor and I don't seem to be getting any spark from it either, but I also tried my old wire that I knew was firing and it still had no spark. Could the coil spark be too weak?

Is the tach moving at all when you crank? Probably if you're getting some spark, but if the crank sensor isn't telling the computer where the engine is it won't be able to fire the coil at the right time.

I will check this once it's warm out, I've kinda narrowed it down to the Crank sensor or Distributor coil

Might not be a terrible idea to verify the distributor is spinning, just to rule that out too.

It does, I checked that when I replaced it

Finally had time and weather good enough to check this, yes the tach moves a little when trying to start, could it still be the crank sensor? I just replaced the distributor pickup coil and no luck there.

The crank sensor tells the computer where the crank is. The sensor in the distributor tells the computer if the number one cyl is on a compression or exhaust stroke so that it knows when it needs to fire injectors (1 cam revolution per 2 crank revolutions). The coil is on the front of the block. I have had bad coils new out of the box from the parts store.
