The engine turns over with the key, so that rules out starter, battery, half of the solenoid, ignition switch and nuetral safety switch.
You "hot-wired" the car and are getting no spark from the coil.
So that means that the "other half" of the solenoid isn't the culprit. Spark is generated in the coil from a signal in the distributor and is distributed to the spark plugs by the distributor via the cap and rotor. So we start at one end and work our way over. Unfortunately there isn't any quick and easy diagnostic taht I know of, other than one piece at a time. (That's why I always keep old "known good" ignition components around.)
I don't want to insult you, but in the interest of covering all of the bases:
Is the rotor installed?
Does it turn when the motor turns over? I ask because I had a distributor shat shear off once, as well as a few broken pins and gears in the past.
Did you check for spark through the coil wire or directly from the coil? I ask this because you need to rule out the coil or the wire itself. If you have spark to ground direct from the coil tower without a coil wire than there is your problem.
If you get no spark from the coil at all you can rule out cap, rotor and coil wire. Try replacing the coil itself.
If still no spark then you need to look at your pickup or control unit or points/condenser depending on what you are running.
If you still cannot get any fire, call me - I will tow it away for a fair price

Just kidding. I am out of easy things to check, so try these first.
Good luck, keep us posted.
