No spark :(
Hey all, it has been quite some time since I've been on here, but things were going smoothly for once! Until....I was driving along the other day and the truck just shut off, and wouldn't restart. It is getting fuel, I checked for loose or burnt wires, busted fuses and anything in between, I had a spare coil and tried that and still nothing. I'm not good at this electrical crud and any help would be great. Oh, I have an 84 with a 302, the duraspark system has been replaced with an MSD box and Blaster 2 coil. Thanks!

Ah, i should have been more specific, my apologies. The motor cut out, all the lights and electronics work, there is just no spark, I pulled a plug wire off and attached it to the firewall while my brother cranked, no spark. It will crank all day but no spark.

Just an idea, but with the distributor cover removed, do the internals rotate when the engine is cranked? If not, you know the distributor is the problem. If it does rotate, it may still be the distributor but also could be your MSD box. Lastly, could there be a loose wire from the MSD box keeping a signal from being generated? Just food for thought.

The distributor is brand new as is the motor. The distributor did turn, i did check that. What i forgot to mention was that the MSD box was EXTREMELY hot to the touch after the truck shut off, I knew they ran hot but i could not even touch it.
I double and triple checked all the wires coming into and going from the box.

It's all good! At least now I have a better feeling that it is probably the box, I'm going to bust out the test light today and prod around, I appreciate the input though! Thanks!
