Sounds to me like something isnt wired right. I'd double check or even triple check everything. One loose or faulty connection could be all it takes. I'm amazed you got it running on two cylinders, well kind of, those motors can take a hell of a beating.

Sry just for clarification, you had it running right after the re-wire or it ran in another vehicle?
