Problems with Tub Swap

My brother and I just replaced his rusty CJ tub with a YJ tub and now we can't seem to get it to start. See he took the body one day when I wasnt there and didn't lable anything, I think he was just exited about the new tub. The Jeep will turn over but we're not getting any spark. The body mounts arent bolted down tight yet, so maybe its not getting ground?? Or we messed up plugging everything back in, I dont know. Im not very good with the electrical stuff, so if there is a messed up connection some where, where is the first place to look first?? Hes got an 84 CJ7 with the 258. Its going to get warm here in a couple weeks and I think he'd like to get it going.

Got it running yet? If not, check for power at the coil. Grab a test light and use it to determine if you have a grounding problem, a hot wire problem, or both. If you are getting power then its a distributor problem. If his wireing remained intact then it sounds more like a grounding problem to me. Good Luck!

I still havent got to run yet. I took the coil out of my 84 and tried it on his; it still didnt work so it must not be the coil. It ran fine when he took it apart so it must be something that we did. I havent really gotten a chance to mess with it much, we've got other issues to worry about right now. Im still looking for the grommet to a line that runs into the gas tank, so the tanks not on yet. I guess once I get the gas tank ready to go I'll tighten down the body mounts and see if that does anything (which I dont think it will). Then I guess I'll just start testing lines like you said. I'll need to take a good hard look at it.
Does anyone know where I could find this grommet? Its a rubber piece for what I guess is a rollover protection line that runs into the tank. The dealer says they dont make them anymore. I know it not on 82 and older jeeps. We are thinking of just pluging it up. Would there be any problems with that?
Thanks for the help.

Look on the passenger side of the engine above the oil pressure sending unit. there is a bolt there attaching a wire to the engine. I know that my 86 CJ will NOT fire if that small wire is disconnected. If it is not connected, it should be hanging around there somewhere close and it has a large "ring terminal" that fits the bolt in case you are looking for it.

Check your fuses first. Mine does just what you describe when it blows the fuse for "Indicator lamps". On mine it is the fuse on the lower right of the fuse block. If I can follow the diagram it feeds into the coil. Hope the fix is as easy as this...
