No spark!!!

Ok, folks, here's my first post, just not what I wanted to start off with. I started installing my suspension lift yesterday ( '87 YJ, 258, 3.5" lift, 33-12.5's,still got more to do), needed some tunes, so I left my ignition on to play the stereo (I know, I know!) Today I finished up, slapped the tires on, and went to start her up and no joy. Checked for spark, and of course there wasn't any. I had recently installed a juice box and did the "Nutter Bypass", so I undid both of these just for kicks- still no joy. Tried manually firing the coil, still no spark. Lack of anything resembling a voltmeter forced me to "shotgun" troubleshoot; an idiot light to check for voltage, and just replacing the ignition module and pickup.
I even went so far as to run my fingers over each wire as far as I could get to check for burns, breaks, etc... Am I missing something, forgot to check anything, or am I being punished for wrenching without beer?

I had a similar problem w/ my jeep. I thought that my coil was cracked and got wet or something... after replacing that it still didn't work... Anyways check the ignition module (it's a silver box w/ 4 wires located under the antifreeze overflow tank.. pain in the *** to get at.)

Thanks, but found it already. Turns out the ignition module AND the coil were bad. I've since rewired the stereo to come on without the ignition switch, shouldn't burn them out again.
