I don't believe yours is a typical EEC-IV system. It has a remote module. I think it is EEC III

Thanks

Back to square one. I think you need to redo your testing.

It seems to take me back to the spark test, should i check it between the coil and the distributor or at a spark plug? or does it matter? If i get no spark how would be the best way to check the coil? even though i replaced it, there is still a chance it could be a bad part but highly unlikely.

Hammer Time I have one question for you on the injector test, while cranking the engine with the node light pluged into the injector plug the light should flash correct?
Thanks

Yes, it should if you have both required signals of constant power and pulsing ground.

So, you do have injector pulse but don't have spark.
Everything there is pointing toward an bad ignition module or related wiring.

Thanks for unlocking,
Turns out that I have spark, I bought a bad spark tester and then bought a bad coil well once i figured this out and put all the old parts back on it wouldn't start but i heard it fire once maybe one cylinder then nothing. I turned the distributor clockwise and it started so i warmed it up a little and put the distributor back to the factory setting still running, not right but not too bad. I then checked the timing, couldn't see the mark in view of the light so i turned the distributor still couldn't see it so i crawled under the truck with the timing light pointed it at the pulley with the timing mark and there it was a 180 degrees from where it should be. Did it jump time?
Thanks

It could have. Might be time to take a complete compression test to find out if the timing chain has jumped.

You looking for the compression readings. Warm would be better but it doesn't have to be to tell us what we want to know.
