do you know anyone with an OBD1 civic that you could try your ECU in their car? Or even their ECU in your car....

Auto to manual - Remove RP17 and install a jumper across RP18. that's it. I've done it successfully many times.

your problem....
with the ignition on, make sure you have 12 volts on the Blk/Yel wire on the two wire plug at the distributor. if no... bad connection on Blk/Yel wire between distributor and ignition switch. (main relay??)
if yes then with the ignition on, is there at least 10 volts at the ECU between A21 and A26? what about A22 and A26? if no then bad connection between Yel/Grn wire from ignition unit to ECU (A21 or A22) or you have a bad ignitor unit.
if yes then replace ECU.

removing RP17 and jumpering RP18 is simply pulling that pin of the micro to ground and releasing the other to float to 5volts, it's possible that the resistor is enough to make the Micro see ground. It's also possible that you accidentally shorted something in your ECU. Or even have an intermittent ignitor...
