I second ohm-checking the ignition coil. You'll need a multimeter but testing the coil is very easy. If you're unlucky like me and the bolts between it and the mounting bracket are rust-welded, you'll have to remove it with the mounting bracket. One of the bracket bolts also passes through the belt tensioner, so you may have to remove the belt to relieve the pressure. Fortunately, the drive belt is super easy to remove on our trucks. You'll need a minimum 3/8 drive ratchet and I think a 15mm socket.
This page explains how to test the coil and what your readings should be. Good luck.
PS: If your woman isn't mechanically inclined and she wants the truck gone but you don't, just throw her a BS answer that the problem is simple and cheap to fix and you have mail-ordered a part, but will take a week to arrive. Worst case scenario if you don't have the truck running by then, just say that something else came up. What you do then will be up to you however. Women have patience if they don't know any better but are completely unyielding once they lose it, LOL.
