I forgot something in my last post. I have the dual cooling fan set up. When the key is in the run position, one fan is running. Is there a chance that I might have the knock sensor wire and the cooling fan switch wire mixed up. It didn't do this before. It never fails, no matter how many engines I have out and put in, there is always something else that comes up and throws me for a loop. Thanks for the info.
