Default 91 crx running obd1 motor with obdo ecu

well i have a d16z6 with obd1 wiring harness for the dizzy and injectors, we took of the rez box, and all the car will do is, crank up, but not run. its acting like its not getting fuel. is it because im running the stock ecu, or something else?

if the distributor is obd1 and the ecu is obd0 its not going to run.

get yourself a p28

Non-vtec ECU on a vtec engine, right? One problem.
Like ^^^ said, get the proper ECU

no - you either need the OBD1 ECU with the OBD1 distributor or you need the OBD0 ECU with OBD0 distributor

Yes it should. Go try it.
Also, he deleted the resistor boxes, which are needed by OBD0.

I read it, but I'm not sure I understand.
You have the harness set up for OBD1 injectors and deleted the OBD0 resistor box.
BUT
what injectors do you have on the motor now?
You can run either OBD1 or OBD0, but you NEED the resistor box if you have the OBD0 injectors in there.

yea it sounds like he put obdo injectors, and he deleted resistor box, so that explains why it seems like its not getting fuel lol

it has obd1 injectors, that came with the d16. hence the obd1 injector harness and us taking out the res box.

So are you are are you not getting fuel?
Spark?
Compression?

Do you have your firing order correct?
Is your timing belt on right?

THey are right. The distributors' internals work differently between OBD0 and OBD1. DIzzys must match ECUs OBD generation. Get a OBD0-1 jumper harness, OBD1 ECU and voila.

Are u kidding me? "obd" differences causing it not to run... yes, but non-vtec ecu in vtec engine NO, it will still run!!! Kno ur sh*t before u give out bad advice

bad advice? really? i am telling him to do it right.
shut up.

he is trying to run obd0 with an obd1 dizzy.
if ecu is obd0, you need those resistors.

Then don't quote my shyt sayin its wrong, it had NOTHING to do wit those resistors, we all know obd0's need a resistor box. MY REPLY was in response to a non vt ecu wouldn't run a vt car, so u jump in wit ur two cents where it OBVIOUSLY doesn't belong, not knowing what ur talking about saying that it WOULD cause the car NOT TO RUN!

show me a vtec motor running obd1 with resistors then.

his set-up is wrong. plain and simple. don't go all internet e-thug on me. you sound real big behind your keyboard.

Are u special ed, or just dumb? I said it WASN'T about the resistor box!
I'll explain it to u one last time... it was about a post from someone else asking if non vt ecu would run vt car, then u jumped in sayin it was incorrect what i put.... that the ecu bein vt or non-vt would be an issue! Also,... lol @ the "e-thug" I don't kno how sh*t is done in canada but maybe you should go back to watching Terrance & Phillip n stay away from hondas

That, is immature. Seriously. Just because someone takes a modified education course, does not make them dumb. Maybe they have a learning disability. Ignorant. Really.

Running an OBD0 ecu without resistors doesn't work. That is what I am saying.

BUT the ECU he is using is OBD0, and that is wrong with his set-up, hence him needing a new ECU.

Oh, you are from the U.S.A. I always wondered what makes you people the most hated country in the world, and now I know. Stupidity runs rich in your blood. Not all U.S.A citizens are like that, but you sure contribute to the majority. Also, Terrance & Philip is not a real show... only a fool would think that.

Jesus, u don't seem to undersrtand anything but yet u call me ignorant.... stop talking about the f*ing injectors, I ALREADY said it was about the vtec non vtec ecu issue. THATS ALL, do u understand?

Really? You said I give bad advice. I said to get the proper ECU. That is also what you are saying.

So you are actually saying he should stick with the ECU he has?

this states nothing about injectors or resistor box, its stating that the "Non-vtec ECU on a vtec engine" is a problem!

Enough said
