they will not fire if they are wet. spray the plugs with starting fluid to clean/dry them, blow them off to dry them & put them in after they dry & shoot some starting fluid in the carb primaries while holding the throttle open. A good 2 second blast. Pump the gas SPARINGLY as in no more than 1 or 2 pumps max & dont pump it at all until it's cranked for a bit. Shoot more starting fluid if needed. We are wanting to get this to fire on starting fluid rather than on gas which is easily flooding it. Lets get this thing going before the super bowl starts.

I would just for go trying to clean the plugs after all the trying you have done and put in a new set. Also when trying to start it with the starting fluid Make sure that the choke is open and that you hold the throttle WIDE open. even if you try the old plugs hold the throttle wide open to unload a possible flooding condition. Leaving the throttle closed only aggravates a flooded condition if that is what it may be and the choices are rapidly running out.
Clean it, if it's Dirty. Oil it, if it Squeaks.
But: Don't fix it, if it Works!

ok, i have a question on the coil ohm readings, they say the terminal to terminal should be 0.75-0.81 ohms, mine is reading 1.5.
The reading from the tower to either terminal should be 10,000-11,000 ohms, im getting 8500, could this be off enough to cause it to not start?

You did say you had a nice bluish/purple spark? Your readings are OK.

well, i took the distributor out of the block and spun it and it is making spark, i even tried the other 2 ecu's that are supposedly bad and they made the same spark, It is a bluish purple spark, i just pulled a plug wire off and stuck another plug in it while i spun the distributor, i also pulled the coil wire out of the coil a little bit and spun the distributor and it made bunches of spark. with the ballast plugged up im only getting 5.5 volts to the coil and with the ballast bypassed im getting 8.5 volts to the coil..still wont run after all this messing, i did ohm the pickup coil and its 276 and it changes if i spin the distributor shaft but ends up back at 276, saw on the tech archives that it should be between 375-425, but i thought these either worked or didnt work at all, meaning no spark produced? what the heck do i do now?
Sounds like it's not getting enough voltage to the coil to me, shouldn't it be around 12 volts starting and 9 volts running when using a ballast?

I think it's possibly a MP(only) piece as some one on here had one for sale the other day & it was in the familiar clear cellophane with MP lettering/logos on it. Most backfires I have heard sound almost like a shotgun & just as loud. The 1st item I check is the muffler.

with the dist on its side supported on either side of the plastic at the right height(with each of the 2 end supports at different heights if neccessary) to keep the dist level, drive the roll pin out with a roll pin punch. The round ball edge on those punches makes a world of difference in getting roll pins out of there.

.! The run side of the dual ballast is .5 ohms, the "641" race ballast is 1/4 ohm & the MP one for orange/chrome boxe in a daily driver are I think 1 ohm so you are way over. You might jump 12V to the upstream side of your ballast to see if it's a voltage drop problem or that your ballast is too high.
