i have a 91 crx hf that i just dropped a DOHC ZC into, the engine came with an si engine harness and my car is an hf, everything plugged in fine, but when i tried to start it i don't get any spark.... if i let th car sit for a few minutes and come back and turn the key to the second position it will give one spark, then when you try to start it nothing.... i'm also getting a CEL code 15(igniton output system)...is this because i need to use the hf engine harness? anyone?
