I'm not trying to be a jerk, and I understand trying to save the $$. But an AC cap, rotor and ICM for you truck would be $84-102 (they listed two different ICM's). That whole distributor setup for $60 has me seriously wondering about the quality of the components. I just dont see how they can be decent parts at that price. This is all just my opinion and I hope it works great for you. These areas are not places I like to skip on the quality of parts, but this also isnt your daliy driver so the setup I posted also could be considered overkill.
On the wires I was comparing them to a vortec set, which even the AC's are $90 or so, forgot yours was TBI when I posted that.
If you replace the distributor just like you described a few posts back all you should have to do is check the timing. If it was correct to start with before you did the gaskets and all it should still be ok. I maybe wrong but a timing problem would be present all the time IMO, but something like a cracked cap or module that is starting to go bad may only happen when up to operating temp. Adjusting/checking the timing is no big deal and really easy. Just get a good light and we can help you with that. I have a Sears dial back light, but if your setting to 0* you wont need that. It mainly helps on older cars where you need to set some inital advance.
I know I mentioned plugs earlier and that could still be a factor. I threaded mine in all the way by hand as well and managed to crack them when I tightened them with the ratchet. Keep plugging away at it, intermittent issues are the worst sometimes....
