Hey everyone, im new to the forum, im in the process of rebuilding an 88 civic dx. Its still has a stock d15b2 and still dpfi. Ive replaced or rebuilt nearly every major component on the car, but i cant seem to figure out why i have no spark. The car ran before the rebuild just needed a transmission. Ive checked all grounds, all fuses, made sure all connections were together, picked up another ecu, tried 2 distributors, 2 spark plug wires, I have fuel, timing is good. My CEL flashes nonstop when attempting to crank the engine, my ecu only lights up once which i understand is my o2 sensor but was told the car will still start. Any help is appreciated

 

Stop yelling!!!

Are you using an HEI spark tester to check for spark?

Do you have power to coil/igniter both when ign. is in run AND cranking to start? 94

 

Has power at coil until cap is on, cap was tested as good with mutimeter. Used the screwdriver and a spark tester.

 

A screwdriver will blow the coil, test the coil. 94
