I have an 89 civic and it has the ugliest dissy that I have ever seen. Its coil is in the unit with its electronics. These electronics are a problem and will have to be taken to a specialist. easier and cheaper to replace whole unit from a wreck or a new one Sorry
Merry Christmas
From your description of the test procedure you are not testing it right. To use a test light at the ht point of the coil (Lead to the distributor) the voltage here exceeds and test light capability and that is probably why you get one spark. (Over 60.000 volts). replace the HT lead into the coil and hold the distributor end of the lead about 1/4 inch from the engine head/block and crack the engine . If the coil is good you will get a spark for each cylinder on compression . If it is bad you will get missing sparks or no sparks.. Place a multimeter on the + side of the coil to earth on and read the voltage with the ignition on . IT should be either 7.5 volts or 12 volts depending on the coil. While cranking the engine it should be 12 volts regardless of the coil. If you are getting the correct readings and the HT lead sparks ok then the problem will be in the distributor cap . Look for the carbon pin inside under the HT lead is ok and clean out the cap. Check that the rortor button is ok and clean and will not turn on the shaft (broken drive section ). If all ok the take the no 1 cylinder HT lead off the plug and hold 1/4 away from the block/head and while cranking you should get 1 spark every 4 revolutions of the engine
Ignition module that sends signals to coil, check crank/cam position sensors as well as map sensor.

I know that early 90's Honda's had problems and in fact a recall on the distributor. Might want to replace the distributor. Inside of the distributor is a part called the igniter which is the ignition module and that is what normally goes out. I cannot remember if you have to replace the whole distributor to get the igniter or if you can just replace the igniter itself. Has been a few years since I have worked on one. hope this helps but if not please contact me. I'm not sure about the drive light flashing thing though, new one on me.
You have not run a OBD2 electronic engione control fault code test, get a code reader and do that first and don't replace anymore parts until that is done and you have the fault codes and have done the proper diagnostics for each code.
