Help Engine Failsafe after coolant transfer pipe replacement

[cj-10]

I just did the URO collapsible pipe replacement and replace the valley pan, the ccv tubes etc. I had the battery disconnected. When I went to restart it sputtered a few times I figure due to the fuel line being disconnected. When it started it idles at about 1000 rpms then it starts bouncing to about 1200 rpms. It sounds like someone is just tapping the throttle constantly. The engine failsafe comes on. I disconnected the battery again to try to reset the computer but I get the same thing. I really need to get this back on the road. I do not have an OBDII scanner.
