Injector problem on obd1 to obd0 swap into 92 hatch Anybody?
Ok here is what I did. I have a 92 civic that had a d15, i had a b18a1 sitting around. it ran just fine, pulled it out, took out the wiring in the civic, wired from the ecu to the motor with all obd0, integra everything, ecu included from the b18a1 motor. i tested the CYL sensor, TDC sensor, and CKP sensors, they all measured good at around 350 ohms, all the injectors measured around 10 ohms a piece, i did install the resistor box, the fuel pump pumps, the spark sparks, the injectors do not shoot, i can make it start momentarily with starting fluid, the fuel goes up to the top of the injector and does not fire, im getting two codes, code 13 and 16 (baro sensor and injection) does anybody have ideas on what this could be?
if your injectors are 10 ohms AND you have a resistor box, that is most likely the problem. As far as the baro sensor, which ECU are you using to run the B18?
i measured the resistance for each injector with the resistor box, so it was 10ohm with the box, i am using the 91 integra obd0 ecu in the obd1 car.
Most likely you have the distributor to ECU pinouts wrong.
The code 13 is disheartening, OBD0 PR4 has an internal PA on the motherboard. You probably have something unneccesary run to C8, I think that's the pin that causes the false CEL 13 on OBD0 PR4 when you stick them into the 88-89 HF; it's been a couple years.
If you had asked my opinion ahead of time, I would have told you to fit the DX engine harness and injectors to the LS engine, gotten the D15 distributor held to the LS by the top bolt (the only one that lines up... my D15B2 is running an LS dizzy atm) and limped on your current OBD1 ECU until you could the correct ECU. Still, you'll definitely have learned a good bit about Honda wiring by the time this is all over. Good luck... not that you'll need it, sounds like you're most the way there.

thanks for the help, ill have to check out the code 13 pinout you were talking about, although im not too worried about that code so much, i dont think the ecu cares so much about it, should still run, i think i found the problem with the code 16, i think the resistor box was wired wrong, im about to run up and give it a try. the first time i wired the car it took about 30 or 40 hours cuz i had no idea what i was doing, second time took about 3, then i wripped it apart and did it a third time which took about a hour or so. i think i have learned a lot in this swap, i just got my body kit today too, things are looking up!!, ill post the results later on tonight
