Car quit starting... Thoughts?

[Calif240]

Figured I would check with you guys so I didn't dive further into this project if there was a simple solution I was overlooking... car was running fine and went out to start her since she's been sitting a week or two. She wouldn't start. I'm not getting spark to the cylinder. Starter spins. I am not getting 12V across the coil. So I checked back and made sure that the ignition switch was giving me switched 12V to the MSD box that I have (6A). I have switched 12V going to the MSD box, and the ground and battery + to the MSD box as required. I've checked the fuse box and any simple wiring that could've come loose. I'm thinking my 6A box went out, but I've heard that they're not known to go out easily. Am I missing anything else? My next step was to bypass the 6A with the switched 12V directly over to the coil and re-wire. Again, figured I'd ask all the experts on here before I jumped further in case I'm just not thinking of something else....
thanks guys...

yea, sounds like the box went south....main reason I'm dumping my MSD as well and going with GM HEI....MSD parts not available on every parts house street corner

Please...
