i bought a 91 civic si.
i have earlyer a 95 civic coupe with b18c5 swap.
i just put it into the old civic but it wont working.
it starts with the pw0 ecu but id does not running fine.it starts but stops,does not idling.
i bought a conversion harness od0 to obd1,and with my old ecu the car does not starts now.
i have checked everything,
but if i put in it my pw0 ecu starts but does not working well.
it smokes does not have idle..
please help me anybody.

 

It won't idle but can you keep it running with the throttle open? If so, it could be a vaccum leak. And use the right ecu.

 

it runs poor.
cannot go fast.with open trhottle it revs max 5000.
hard to start no idlle.only with open trottle.

 

was that with the obd0 ecu if so try checking the vaccum lines once again and then use your obd1 ecu it should run fine..........otherwise it could be a distributor problem i had a problem like this on my crx found out it was the module in my distributor so replaced it and after that it worked just fine....my symptoms were puttering and when i would try to reach high rpms it would bog out alot and jst like you wouldn't let me go past 5000 rpm good luck let us know what it was when you find out....

 

with the obd1 ecu the car wont start...

 

Just to be sure....check if you have gas in the car.....cause man, I spent many hours trying to figure out what was wrong with my buddies car one time and after a week we found out he had no gas.

But anyways
1. if you use the OBD 1 ecu you should take out the Resistor box for the injectors, or get some OBD0 injectors if your gonna use the resistor box.

2. Check your firing order, check to see if it gives spark with the OBD-1 ecu, check for fuel, do you hear the main relay clicking?? Is the gas in the car old?

Good luck and let us know whats the delio.

 

hi!

i have fully loaded the cer with fuel before i made the swap.
i have cut out the resistor box.
the main relay works.
the fuel goes to the injectors...
look for this:
i have removed the resistor box andd the car still starts with the obd1 ecu and does not starts with obd1
i dont have any idea now

 

"car still starts with the obd0" !!!

 

Who did the Dizzy conversion??

Make sure the wires are in the correct order, for the OBD1 dizzy.

 

conversion:boomslang

 

I am not asking about the ECU OBD0-OBD1 conversion harness....

I am asking about the Dizzy wire conversion....who did the dizzy wire conversion or did you buy one of the plug adaptors for the dizzy also?
