Hoss,
One post is enough. Multiple will only **** people off who may be able to help you. And for future reference, include your year, model, engine, tranny, 4x4 or 4x2 in your post (or in your sig) and title that post something like "94 5.0 no spark from good coil and tfi" and then try to include what you've already diagnosed/tried.
the Help me's just show you didnt read the two READ ME Posts...

First off I want to say welcome to FTE.
Second I liked the post by Popa Tim, good show.
Third as you all may have gathered by now I am not a part changer to try and fix something. Sometimes changing parts can cause more problems than you started with.
Fourth I would like to know the posters skill level and what he has to test with. I would hope it is a test light, I do not like meters (DVM) for trouble shooting as they lie a lot (they do not load the circuit) and cost you a lot of money spent on the wrong parts.
Fifth can the poster read a diagram (print, schematic).
That said, what was the problem again (I have a good memory it just does not last very long), oh yes no spark.
I think you said you changed the tfi module, the distributor, ignition coil, distributor rotor and the EEC Module then reset the timing.
You asked what is left, the Fuse Links, Ignition switch, EEC power relay and plugs and wiring.
To start with do you have power on the POS (+) side of you Ignition Coil with the key on?
If so does your test light flash on the TACH (NEG, -) side of you Ignition Coil while cranking?
If you do not have a test light get one if you want to trouble shoot a problem like this one.

Thanks for the reply, I have changed the eec relay and as the test light I do have power on the coil with the key on but the test light does not flash when the engine is cranking over.

I am a former Marine and know all about conforming to rules so I know not to let the true me get out in this web site cause i am useto useing profain langage AND NOT BEING LOOKED AT AS BEING A CRUDE PERSON!

But he was not too clear on this. I was hoping he would come back and clarify this when I talked about it above but did not.

I put a comma between each part name and I was hoping for a come back if I was wrong.
