Could be the crankshaft sensor.

If you have a new distributor cap & rotor on there also, the only thing left is the Ignition Pick-up Coil inside the distributor.

Thats new too

Well then I would make sure the rotor is seated correctly, make sure it is the right cap and rotor. Something is defective.

You know, I did read somewhere that if the crankshaft sensor is not positioned right, the depth it sits at, that can cause a problem like this. May want to search to see if you can find anything on this.

Also, you may need to check the wiring to the crankshaft sensor, may be a break in the wiring.

That crankshaft sensor pulses off of a reluctor on the crankshaft. It makes a magnetic field that collapses when the reluctor tooth goes on by.

That tells it to spark right? Well its sending soark to top of cap just not going through the rotor to the pins for the spark plug wires. Now why would i have 15.5 volts at the battery without it running? And its sending almosrt 14 to the top of the cap now i understand while running it should be around 13.8 could this have anything to do with it?

Oh, forgot about that, your alternator is over charging. Either replace it or it needs a voltage regulator. And no, this would not have anything to do with this. Remember the old points that use to be in the distributor? When there closed the coil builds up its charge and when the points opened, it would release the charge to the rotor, and distribute the spark? The crankshaft sensor is doing this when the magnetic field is broken each time a reluctor tooth passes by the crankshaft sensor. So it is a new crankshaft sensor which makes me believe that there may be a broke wire along that circuit. It usually happens at a plugin, wires will break inside the insulation. There should be 12V on one side of the wires going to the crankshaft sensor.
