The plugs were a little wet, and i did go get a new can of starting fluid, still same of course, could the dang coil be bad but still produce the spark im seeing? Theres just nothing else, the thing must be haunted or something, everything seems fine..

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!

Im out of time today. Thing is, after sitting a week the plugs wouldnt still be wet and causing it to not start, remember, i started working on this thing last weekend..

That is right but they could be coated and not fire.

Yes they would because you have done nothing to dry them. Gas won't completely evaporate in a closed area like a cylinder.

Also I might add that once fouled a plug is very tough to get to pick up proper spark. Even after cleaning they sometimes take awhile of running to completely clear. (if they do)

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?

pulled the distributor back out and pulled one plug wire off and stuck a plug in it so i could spin the distributor shaft again to be sure its still firing the plugs, i guess i should have unplugged ALL the plug wires from the plugs still in the engine because when i spun the distributor shaft the car backfired louder than ive ever heard in my life! My wife came flying out of the house..i hope it didnt hurt the engine. I put the distributor back in and buckled it back up so i could turn the engine over to see if it sounded like it hurt anything and it sounds fine..and hopefully it is. I will get new plugs next.

Something i have to get and dont know where, there is a plastic bushing that is pinned on the distributor shaft that keeps the shaft from going up and down, when i pulled the distributor out it broke apart on the floor. This is not the bushing everyone replaces with the bronze one, this is on the distributor shaft itself under the base and keeps the shaft from going up and down. None of the parts houses stock it, anyone know where to get one quick?

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.

as i said, i can take spark plugs and put a plug wire on them and spin the distributor shaft and they will blue spark, but i borrowed a spark tester from work wich looks like a spark plug with a clip on it, you hook a plug wire to it and clip it to the block and see if it will fire, it wont fire that, but will a spark plug. We use these testers on cadillacs at work and im not sure if the old mopar ignition should be strong enough to fire one of these anyways...?

ok, before i can go any further i have to replace that bushing on the distributor. I have another old junk distributor with the bushing, the question is, how to knock the roll-pin out of it without busting the plastic bushing..?

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.

In a used distributor it is unlikely that you will get it wou and back in with out breaking it. Your local Chrysler dealer should still have them: They have been the same for many years.
Have you even tried to start the car from under the hood there by eliminating the ignition switch start side as a possible cause. All you have to do is to turn the switch to the run position and and jump the 2 terminals on the starter relay to spin the engine over. operating the carb by hand. doing this make sure that the transmission is in neutral.

I believe MRNOBODY is on this like like gas on your fouled plugs.
Seriously I just went through a no start,hard start situation. First if you have a propane or oxygen acetylene torch heat plugs until the porcelain is white. Do not melt electrode as I have.
In the cranking mode I had 9 volts and wouldn't start unless I put the battery charger on start? got me thinking? swapped my good battery into R/C. Still no consistent quick crisp cold starts. I had changed from the dual pick up dizzy to a standard single pick up dizzy. I gaped it at the factory spec of .008 when I installed it? SOOOO I used my dial calipers and found plastic that was .004 loosened my magnetic pick up slipped my high tech red neck feeler gauge in the pick up gap and adjusted. YEP you guessed it that fixed my problem.
Not to be pushy but double check the pick up gap and get more voltage to coil.
I was following a questionable mechanic who had also used the coil + for power to the MSD 5al not 6al box. Good luck

well, put new plugs in it and now its running!!! Thank god and you guys! Guess you all were right and fouled the plugs while cranking with the bad ECU. Im still only getting 5.4 volts at the coil while the car is sitting there running though...I have the single ballast 1.5 ohms, shouldnt there be more than 5.4 volts at that coil while its running though?

You're gonna laugh when you find it


Chad are you smiling! After all this thinking, analization, dissecting & hair pulling it was the plugs .! 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.
