no spark

I went to fire up my 87 wrangler with a 258 and she wouldn't start.Checked all the obvious things, cap,rotor,wires.I am getting power into the coil but nothing out.I had recently swapped to a T.F.I coil(juicebox).Thinking maybe it went south I reconected all my original stuff.Cap,coil,rotor,and wires.Still no spark.Doesn't seem to be any burnt or bad connecters.I am thinking of switching the ignition module to eliminate that as a problem.I'm running out of ideas.The jeep ran fine when parked the night before and even briefly started that morning.I have a manual choke and it is getting gas.What do you guys think.

I drive a '90 with the 258, and my younger brother drives a CJ-7 with the same 258. He is having a similar problem, and the problem is in the plug for the computer. When the jeep is cold, he has to wiggle the plug or he gets no spark whatsoever. Neither of us have done the "infamous" nutter bypass, but we're going to try it next weekend to eliminate the computer and see if that solves the problem (because the ignition module passes through the computer on the way to the cap--we've been kicking around the bypass for both jeeps for a while now). I know this isn't a definitive answer to your problem, but like our situation, it could be something as simple as a wiring connection.

Currently an '86 CJ-7 and a '77 CJ-7 Golden Eagle---#4 and 5 following a '01 Sahara, '90 Sahara, and '85 CJ-7....

Let me know how it works out. I'm thinking about getting the Juicebox too. If this is something that I will come across, I might think twice bout it. Thanks

The good news is it had nothing to do with the juicebox.I replaced my ignition module and it fired right up.Now if I can just sort out my carb completely.
