car is 2000 civic ex with b18c...it runs fine with the jdm ecu the swap came with but will not start with a 98 (no immobilizer)usdm ecu i have to install and run for emission??? havent looked closely at the car yet but i know it gets fuel??? just wondering if there is a simple answer to this problem that someone knows about??? i dont know if my ckf sensor is wired correctly???? would that be it???

i tryed the ff squad ckf trick but still wouldnt start...now with my jdm ecu i have a code 9 cyp sensor????

 

 

Any chance the us ecu is just bad? Does it work in someone else's car? I believe it should run without the ckf on a US ecu, just not very well. I'm about to do a jdm b18c in to a usdm GSR. I'm gonna put my ckf sensor on a new us oil pump and put it on before the swap.

 

i have the ckf hooked up i believe correctly and plan to check it out in my buddies car tommorrow

 

AM bump

 

afternoon bump

 

so i got it to run holding down the gas...wont idle at all...and i got 3 codes

9 cyp
41 O-2 Sensor Heater
65 Secondary O-2 Sensor Circuit

BUT my buddys 98 integra with an odb1 b16 wont idle either and he gets a

ckf and vtec code

help me please

 

The US 98 Integra ecu has a completely different pin configuration than your 2000 Civic EX. Go get an OBD2b-2a ecu adapter

yeah...i got one of those

 

man i think im having the same problem you are right now. i cranked it over for the 1st time on sunday, i got spark, got fuel. have to keep gassing it to stay running. have you tried adjusting your idle yet? i have a fuel leak and i just havent had time to fix it yet so i dont really want to go further but i planned on adjusting the idle as soon as i fix the leak. im not even sure what codes are going off cause im using an obd1 ecu and the scan tool doesnt read, plus its a 97 i dont think theres a place to jump the codes. my ecus is suposed to have the secondary o2 disabled but whats up with that cyp code? for the crank sensor the guides say to just match up the colors and clip the extra 3rd wire. i cut the brown one and matched the other colors.

oh i got a 97 dx with the jumper to a basemap p72. i wired the vtec soleoid and pressure switch. knock sensor is disabled so i didnt wire it, i had to extend the o2 sensor and extend the crank sensor. i also did the iacv trick moving pin a14 to the empty a12 slot and cutting a13.

 

i replaced the dizzy and still a code 9

 

hey my car was only staying on if i gave it gas , no idle at all. i went over the iacv wiring again and now it idles perfectly
