Its time to trouble shoot this problem. You need spark/ air/ fuel. So don't replace anymore parts. Reluctor has a air grap.

NUMBER ONE. Turn key to "run" and hook meter to key side of ballast and battery positive. You should read VERY little voltgae, less than .4 (4 tenths of one volt or LESS)
NUMBER TEU. Hook meter to coil + and batter + Crank engine using the KEY. You must use the KEY for this test. Again, you are hoping for a small reading, the lower the better, and not over a very few tenths of one volt
NUMBA THA-REE Remove all connectors from the ignition, ECU, ballast, distributor. Work them in/ out and "feel" for how tight they are.
Insert your meter into the distributor harness connector, and measure ohms Report reading back
With your meter still hooked to distributor, put meter on low AC volts and crank engine. Distributor should generate 1V AC
Carefully examine reluctor and picup for debri, shavings, and strike damage. Obtain a non-magetic feeler which is .008" (inches not mm) and set the reluctor to pickup coil gap. Check carefully that the reluctor does not strike the pickup coil.
NUMBA FOW_AR Remove the ECU, file / grind the mounting bolt area to bare on both body and ECU and remount. Use toothed lock washers, and it does NOT hurt to apply an extra ground wire to one of the mounting bolts and run over to an engine bolt.
Hook up system. Turn key to run and check coil NEG with a light or meter. This point should be "low" that is 6V or so on coil + but much less on coil NEG. If coil neg is high, recheck ground on ECU, and if still high, replace ECU.
When you check for cranking spark, and get none, USE THE KEY, not jumpering the starter relay. Cranking with the key engages the bypass circuit and supplies hotter voltage to the system
NUMBA FY-YIVE Another thing to try is make up a nice big long clip lead, and jumper (hot wire) from the coil + to a battery connection. Don't leave this on for long. You can now jumper the starter relay to crank if you wish, and should get a good spark out of the coil.
As usual, check the ballast resistor.
