Hey welcome to the forum. The same thing happenned to me in my truck. Turns out the coil got soaked. If its not the coil then maybe a new distributor cap and rotor, even plug wires could be in order. Also, check to make sure all the connections are good, especially those on the cap on the coil, the alternator, or the distributor as they have a way of shaking loose. If it turns out to be none of those things, then the fuel filter might be plugged. Lastly, there might be a vacuum leak on the gaskets to your intake manifold or your carb/throttle body. Hope that helps.

Coil, spark control box, condenser, coil wire, ignition module...so many possibilities to check. Buy a Haynes manual, and a multi-meter, and start eliminating the parts that do work until you find one that doesn't.
The spark control box (mounted on the inner fender, silver or black square box, with wires running to the coil) is often the suspect for absolutely no spark. To be on the safe side, if you replace it, take it with you, or at least make a wiring diagram with the colors of wires and in their particular order on a piece of paper. Ford made several of these, some different colors cross over, but you have to be able to figure out if a certain other color of wire does the same job as the color scheme you have. It's easier to find one with the right color scheme(plug and play).
Coils generally out-live the vehical, the odd one falls prey to heat soaking. It wouldn't be the first part I'd suspect. The ignition control module on the side of the distributor is another part I'd lay odds on. If it were me, I'd check the control box and module first.

The box described above does not exist on an 86. 86 was TFI. Previous years used the box and it was called Duraspark ignition.
TFI module is on the side of the distributor. They tend to fail when hot, but I had one that just up and died one day. This part will take a special wrench to remove and you will have to loosen the distributor and rotate it to get to both fasteners.
If done correctly, you can avoid retiming the engine.
TFI is about $25. Tool is usually about $5 - $7 (can be bought at parts store).

TFI is not found on all 86's. The only definite TFI bearing engine is the EFI 302, there are lots of 86 DS-II ignited 300, 351W and 460's out there, and the 351W and 460 stayed carbed into 87, both with Duraspark ignition.

I agree with the module suggestions.
Another 2 second check while looking for spark is to ensure that the rotor under the cap is turning.
It's a nasty possibility. While doing spark checks just pop the cap off while someone is turning over the engine to make sure that lil sucker is turning in there. Rare yes..... Did it happen to me ......yes. Bottom gear of the dizzy chewed off a gear tooth or two.
Good luck

What engine is in this truck? I'm curious, as it could help narrow down the potential list of available options for ignition, etc.
The I-6 engines used timing gears rather than gear and chain sets, and they were nylon toothed and very notorious for spitting out teeth after as little as 20,000 miles.
