Cranks but won't start!

My truck began this odd sputtering but would idle OK as long as you did not give it alot of gas. My first guess was fuel filter / pump. I have since checked the gas flow from the filter to the carb and it seems to be fine. Next, I guessed junk in the carb, Nope, checked it (weber / edelbrock) by removing the top "hat" and it was clean. My next step was to look for spark, pulled a plug, grounded it to the frame and looked for spark, but didn't see any. Now I was onto the distributor added new cap and rotor, tested the coil with ohm meter (OK), then down to the pick up coil (which had an odd reading of 178 ohm) which is supposed to read 500-1500ohms.
I ended up replacing the pick up coil and module while I was digging around in there. I then re-stabbed the distributor and still no fire.... WTF?

I am looking for some advice on next steps to take...

Check to make sure that you are getting power to the coil.

Oh yeah... I do have 12 V at the "BAT" terminal

Hmmmm......

Have you tested other plugs? Perhaps it is a bad wire and or plug?

Is the "button" making contact from the coil to the tab on the rotor?

could be bad plugs bad plug wires bad gas or you could have a short in the power wire to the coil I would change the plugs and plug wires and then clean the **** out of the carb with some carb cleaner

84 I belive had ESC. On the fire wall between the blower box and the distributor will be a harness going through if you have it. There is a control modual behind the glove box.

Did you check your fuses? The ESC I believe is on a sperate fuse from the coil (where you would have checked power at on the cap).
