I would spend the 25-30 bucks on a tow home first.....unless it's far away or they charge by the pound.....

As has been said, throw in a new set of points James!  They can look like new and still be bad.  Please don't start tearing Susan apart until this has been tried.

You want the feed side First.  It would be easier if you just checked it with a test light.  They're pretty cheap.  The brighter side is the high side of the resister.
 
Start with running a jumper from the + side of the battery direct to the blue wire on the coil.  If it starts, then we work our way back.  Don't run it too long like that.  If it doesn't start, then you may have a bad coil or bad condensor.  Make sure you still have a gap in the points.
 
If you put in a new set of points a while ago, and didn't lube the point cam, the points cam will wear down real quick and eventually close the gap to a point where the points don't so anything.  It's only plastic.

Yeah, what Steve said...I wouldn't go replacing the wiring harness,
diagnose your problem first. And the 383 harness on eBay is likely
somewhat different than an A block 318. Those ballast resistors are
notorious for just crapping out, I'd check it - and always carry one in
the glove box...

NOTHING. and it seems that i'm getting power from the resistor. (as i got some sparks when i undid the coil wire). whats next guysFoamy_3022008-06-15 15:09:40

Did you check the point gap like I told you?
 
Disconnect the wire at the ballast Resistor and connect that wire to the coil again.  If it sparks like you just said, then the coil is good.

Check the lead wire from the points to the coil.  Maybe just spend 4 bucks and replace it.  Put a new condensor in it too.
 
Make sure the wire is not chaifed or bare and touching anything.

Is someone else spinning the starter and you have the primary coil wire near a ground?
Pull a dollar bill through the points to claen the face.  The dollars are abraisive enough to clean them.
 
Is the battery in good shape?  Make sure it's fully charged.
 
You know you can jump the starter relay with a screw driver. . . .  Go between the big terminal with the nut on it and the brown wire held on with the screw.  The brown wire goes to the starter.  Stick a wide scre driver between them.  With the key on, you can try to start it that way and check to see if you actually have spark by holding the coil wire near a ground.  (About a 1/4 of an inch.
 
Check you cap and rotor for cracks too.
