Let me see if my understanding of how an ignition system such as mine works is right. The pickup (stator) in the distributor that the TFI module plugs into, and the module control the firing of the ignition coil, right? Once the coil fires it sends the energy to the distributor cap, which somehow gets it on the rotor, which sends it back out the cap to the plugs. Is this correct?
Also, if all that is correct, then in my case where the coil is firing does the problem have to be related to the distributor cap, rotor or plug wires? Or could it still be something else? Even if the timing is off wouldn't there still be a spark at the plugs, just not at the right time? What is really odd is that this happened suddenly, it used to start fine and now it just doesn't send spark to the plugs. The plugs, cap and rotor are all fairly new. The wires were fine when I tested them awhile back, but I think I'll check them again just for fun. Any other suggestions would be greatly appreciated.

ok so you took off the coil wire and you have spark between the coil and the coil wire, is that correct? if so then you need to see if you have spark between the distributor cap and the coil wire? that will tell you if the coil wire is good. if you do then since you already stated you dont have spark at the plugs, you probably have a bad cap or rotor you said they were resonably new but even a new cap could have been dropped by an autozone techinician and cracked.

after i replied i thought of something well two somethings. one did you check to see while cranking the rotor turns? two what color was the spark at the coil if it was verry yellow or orange you may just not have enouhg juce to got through the coil wire jump the rotor and through the plug wire sorry to rant good luck!
