hey guys i need some help. heres the story have a rb25neo swapped s14 i previously had no spark and no injector pulse so after some diagnosing i found i had a bad cas. i swapped out the sensor pick up from a s1 rb25 (metal case) and installed it into my cas (hitachi, black case). heres my problem i have injector pulse no spark when i have the signal wires wired one way and when i swap the two signal wires i have spark no injector pulse. so my question is why am i only receiving one signal? i checked for continuity and the wires are ok and the grounds are ok. any advice is helpful thanks
