I just got done doing the wiring for an OBD0 to OBD1 conversion on my EF civic, and (surprise surprise) it doesn't start. I'm too tired tonight to keep going at it, but I did manage to find that I don't have any spark, I do have fuel, and the only trouble codes I'm getting is for my O2 sensor which admitidly I havn't hooked up and wired in yet. In my mind, the absense of an O2 sensor wouldn't throw the computer into a tizzy and pull the spark, would it? If I had wired the TDC/CKP/CYP sensors wrong, it would probably kill the spark, but wouldn't the ECU catch it and throw a code? By no means am I looking for a magical end-all answer to this, as I still have alot of avenues to look down, but I am looking for suggestions and any useful input, thanks.
