we still don't know if you have 12v at coil.  now history points to interruption in ignition primary circuit.  the big spark when cd player was taken out indicates a fusible link and/or wire and/or connection was fried.  that would mean no voltage at coil.  check fsm for test procedure for primary circuit.  more than one problem could have happened when the Big Bang hit.

did you check for power at the coil when the ignition is turned on?
yep, sure did, plenty of power. Light shines bright!

Did the CD player incident happen before or after there was power at the coil?

Before he messed with it, the car started and ran fine. Ater that jackass messed with it, the car wouldn't start, because no spark from the coil. I've checked ALL that connections, EVERYTHING has the voltage it's supposed too, according to the 1987 Dodge service manual I got from my local library. I know the way I'm explaining this is quite confusing, I'm not very good at explaining things. I have checked the coil every way possible, It has 12 volts coming to it. It's just not coming OUT of the coil.

Is the coil well grounded?
When you say it isn't coming out, do you mean the big wire that fires the plugs or the small wire that goes to the distributor?

try your friends coil on it then if your that puzzled, if it fires up you know where the problem is and then you can buy one of your own, worst case you waste all of 15 minutes to find out that isn't causing it and don't have to spend a dime

According to what he's already said there's power at the coil and and he's already checked the coil and distributor with another car. It's time to dig out a manual and go through the wiring.

   O.k. Please forgive me for this STUPID question. Are the fuseable links the black rubber things in random places on the wires? Most of them are about 1" long by 1/2" tall. If so, I'm just going to bypass all of them to see if that's my problem. Thanks to everyone for their help!!!

Those sound more like the different plugs. The fusible links are a small group of wires in the wiring coming off the battery sort of in the middle of the driver side fender.
