Well my dads truck is a PITA to get at the coil, and I looked at it again tonight and it's arching all over the coil and you can actually hear a tapping from the sparks so I think i'm going to go ahead and replace the coil. Gamma, do you know what to look for in the "new" msd coil? Truckperformance has em for 35 bucks...but I don't want the same coil if it's a design flaw...

That one has some black in the top of it, mine is all red.
Eh, the heck with it. I am gonna buy an accel super coil...34 bucks! heh.

Well today I decided to put my dads coil in my truck, didn't help. I even disconnected my MSD 6a box and that didn't help either. I am gonna have to bring it in to this guy I know and see if he can find anything. 
Oh, and the "new" MSD coil is the "blaster 2" with a black top, the one I have is just a blaster coil w/ a completely red top.

Ok, more new events.
As ya know I put my dad's coil on my truck and it didn't help the situation at all. I drove the truck to school today for my exams, and got some food w/ friends after. Went to leave, and the darn thing wouldn't start. Check connections, had fuel, no luck. Decided to disconnect the MSD 6A box and plug in the normal factory wiring. With the MSD box, you get a little harness. You plug the connector off the coil into their harness, and then plug the new harness into the coil. So I disconnected that and just plugged it in the way it was origninally. Truck starts up and runs, but actually a little worse then before, but it runs. So I'm on my way home and after a minute of driving I noticed my tach needle boucning a little when I was at the stoplight. It's not bouncing relative to the engine RPM either, it was bouncing down the highway about 100-200 rpm, and if you rev it in neutral it'll follow the rpm sweep of the engine but the tach needle is not smooth its "bumpy" for lack of a better term. So this leads me to believe there is a bad connection at the tach pickup on the coil or there is a bad wire there and the tach is having difficulty picking up the hardly existing electricity going through it. I'm gonna have a look at those wires later on and see if I can find anything. I'm also going to try and find out what codes I'm popping out.

I'm thinking it's your PIP sensor inside the distributor. Since your tach suddenly went nuts and your firing is off, that'd be my guess. You may have your Ignition Module checked as a precaution, but that thing normally goes... and that's it. There usually isn't any kind of in between. It either works, or it doesn't.
So my guess is the PIP sensor.

could it just be that your coil wire isn't keeping the electricity in? you saw the sparks... sounds like I'd give it another try
oh well - best of luck!

It's got nothing to do with the wires/cap/rotor/plugs...the coil is a different one from my dads truck. I put my old coil in my dads truck and it ran fine. I took out the MAF system and its still running like crap (and I knew it wouldnt fix it but nobody I talked to in person believed me)..i'll find it somehow
I popped a code 72 out of the SD computer today...after 2 weeks of being in there...I'm in the process if trying to completely understand what that code 72 is and where to check..then go from there.
