Problems with the Civic P29 ECU In my country, the Civic came with the P29 ECU, it is very similar to the P06. Let me summarize, I have a year 95 civic d16a9 DOHC engine in your country it would be like d16zc DOHC. The car started to fail on the road, I stopped and opened the hood, lifted a cable to test which cylinder was failing, suddenly lifting cylinder 4 turned off. and it didn't want to turn on. I managed to tow it home and while testing I noticed that the injectors lost their pulse. If I pour gasoline through the intake it starts but it goes out as soon as the burn occurs. I have a friend who provided me with his ECU and with his. The car starts clearly as it is programmed for h22, I think it works very well. So I open the ecu and I notice that it has several repairs. I come to the forum to see if it has happened to anyone and what part of the ecu they recommend I check. I assume it's the ECU. Because if there were ground, cable, false contact, injector or connector problems, it might not start with the other ECU.
