Hi to all honda community!!!
I have a honda 1997 civic coupe with a d16y7 engine bought in 2005. In 2006 a make a complete b16a jdm obd1 swap. Since the I had b18c ,gsr b18cr and the last 4 years I have a b16 turbo. All engines are with same harness and distributor with msd kit(cap rotor external blaster spark plugs) same ecu p30 jdm. A year ago decide to put the honda rulez cop mini with coils. It was running perfect. And after 6 months decide to buy an s300 but the dealer bought me s300 for usdm not jdm. Since the the s300 has a problem with rom from factory I wait for new one but jdm. After s300 the car has a hard start and cel code 9 apear. I measure resistance from inside the comecrors of the ecu was ok. I replace distributor with new one from honda and but same start. Replace harness same thing replace ecu same thing. Making replacements the coils and the cop mini board were on. Replace the sensors in the dizzy same thing. And the car only cranks and having back fire smels gas. After that I put again my old distributor with mad kit. The engine cranks starts for a 5 secs and push left quickly the throtle pedal runs like 3 cylinder and after suddenly cel code apear ani the engine works clear. But when I turn on the engine same thing in start...

Any help would be apreciate and hope the information I give were clear to you and sorry for any word mistakes. I'm from Hellas!!!
