i have a 89 civic hatch with a B16. at first i just converted the DX wiring for the motor. but it was a bit touchy. long story short i got Multi-port fuel injection wiring. the dash harness is from a 91 HF, the back harness is from a 91 SI crx, and the engine harness is from a 91 EX. now heres the problem. i have fuel but no spark. there is power to my dizzy and i have a check engine its throwing a 6 ( engine coolant temp) i have checked grounds, relays, plugs, ignition module. just don't get it. the only think i can think of is that the EX engine harness is different than the other wiring. or there might be a short somewhere
