i thought you were talking about the connector on the dis. that is your whole prob. if you look at the stock conector on the coil it has a whole bunch of plastic so it wont collapse the field. if it is just in the open it will colapse the magnetic field early and you may get 10,000 volts to the spark plug and look like you have spark but in reality you need 30,000 at least to run on these motors.
ps i suck on paint

pull number one plug bring #1 piston to top dead center of compression stroke pull dizzy cap and see where rotor button is sitting if its jump time it will be off from #1 terminal make sure 0 is lined with timing pointer on harmonic balancer if all is well check your vaccum line running to your map sensor. shot in the dark but had that happen on a friends bronco but it would crank just wouldnt stay running they worked on it for over a year.changed everything even the map.they finally gave up and came and got me and i lucked up and spotted the vac line had melted to back side of exhaust manifold. i am not familiar with your year model just figured i would throw something out there. good luck.

Ok,on the coil,you should have 2 wires on the positive side,one is black that is supposed to go to the radio noise filter,the other is red/light green from the ignition switch. On the negative side it shows a dark green/yellow that goes to the ignition box. That brings up another possibility,being an '86,it has the duraspark ignition,and those things are notorious for going bad with no warning. If it has'nt jumped time,I'd take the duraspark box to the parts store to get it tested.
