If so, try tapping on the starter solenoid with a hammer (lightly) before trying to crank it.
Just my 2 cents... good luck & keep updating this thread.... I am sure others will have more input to provide.

If you floor it does it backfire or anything?
Take a spark plug and plug it into one of the spark plug wires and lay it on solid metal and then watch it.
Id probably start with the coil if it isn't getting spark. You can test one with a volt meter.

So I got into it a little more last night. It is definitely a spark issue. The coil seems to be doing its job; rotor, cap, etc look good, as do the wires. I put a rebuilt distributor in about 6 weeks ago, is there a chance the ignitor is bad in the distributor? Any other ideas out there?
If it was running ok after you installed the rebuilt disty, I think you can rule out the ole' 180 degrees off issue. Yes, the ignitor may have gone south...
But a few questions come to mind...
Are the coil and disty the same brand? It is well documented here that a mix of hitachi coil/nippo disty or vice versa combo kills components. If this is the case your ignitor is most likely toasted.
While cranking what voltage are you reading off the battery? If it drops below 8v (iirc) it won't be hot enough for a spark. Basically this means a weak battery... charge it up or get a new one and try again
The plugs maybe fouled by gas... try a new plug when you pull the wire to check for spark.
Have you taken a voltmeter to the coil? Is there juice on the + and - side with ignition on?
While cranking, are there pulses on the neg side of the coil (test light helps here)? If you do have pulses on the neg side most likely you have an ignition amplifier issue.
Is the ign amplifier grounded properly? It wouldn't hurt to clean up all of your grounds anyway...
Have you tried a new high volt wire from coil to disty?
Sorry for the bundle of questions. I feel your pain. Hang in there...

So is it up and running now? fixed?
btw, I would watch out for the Excel coil, based solely on the statistics posted here and other sites. They seem to be way too much overkill; however, my 84 was purchased with one (an excel coil matched with a ND disty) and it has been running like a champ for a 1 1/2 yrs now like that... so its really up to you what you want to throw money at and try. wires however... i personally have to recommend Subaru OEM without a doubt. Too may issues with other makes...
Sorry guys, I have been away from the interwebs. The disty was bad. I had put in a A1 Cardone reman one, and well where the wires hook up to charge it, the original replacement was completely different that the new one that I just put in. I am going to guess that is the issue, but this hitachi-nippo thing has me interested. I will have to check into that and see if they're different. If so I'll have to come up with something different. Maybe its time for a Accel coil.
