This is just an educated guess, but it sounds to me like either the ignition coil or the distributor itself.
Checking the coil's resistance with a volt meter (on the ohm setting) is very easy, The tests I ran on the coil in my '92 D16Z6 would work for yours as well.

from the positive (A) terminal to the negative (B) terminal, the normal reading is supposed to be .6-.8 ohms. On both my bad and my good coil I got 1.2-1.4 so don't let that throw you.

From the positive (A) terminal to the secondary winding terminal (w/ the spring) the normal range is 13,200 to 19,800 ohms. My old coil, that gave out, measured about 8,000 ohms on this test, but the new one was around 16,000 ohms.

You can also check for power, with the ignition switch on, at the 4 wires that go onto the ignitor. Remove all four before your turn on the ignition, and turn the ignition off again before reconnecting them just to be safe.

edit: the black/yellow wire is from the ignition switch, the white/blue wire is from the ignition coil (obviously), the yellow/green wire is from the ECU, and the blue wire goes to the tachometer.

If one of those doesn't have power, the issue could just be with the wire itself, or whatever it links to of course.

If all of those check out, and so does the coil, but there's still no spark, I would have to be the distributor itself or the ignitor.
