So I am lost at this point. I have had a couple other Mopar guys look at my car and still can't figure it out. I have a 1967 Coronet 400 with a 383. When I replaced the header gaskets, I noticed that the plug wires were arching off the headers. So I went and got new ones. Now will not start.

The new ones were 8MM not 7MM like were on it, so far I have heard both ways on whether or not that would have been the issue. It is a mood point now because I put 7MM back on it. I cleaned the cap, checked the firing order, checked the ballast, new coil, new plugs and gone over the wiring at least a 100 times to make sure I did not accidently unplug something. I am not getting any fire out of the plugs.

Everything seems to be leading to the distributor now but what are the odds that in the couple of minutes it took to change the wires the distributor went and how? Looking for some ideas before I just go blow $400 on a new distributor in case that is not it.

 

7-8 mm would not make any difference.. What kind of dist do you have ?? for $400

 

Pull the cap, spin it over and if you got an arck at the points?
If not get a test light and see if you have power to your points?

 

Power to the coil + side??? Condenser or points could be bad if it were arching to ground...Bill

 

It could be the pickup coil in the distributor. Check it with a good multimeter. Put it on millivolts and see if you can register any will spinning the end of the distributor.

 

TVLynn - I have a Mallory Unilite on it right now.

Everyone else - Thank you for your replies. I messed around with it some more last night and it seems everything is good and the way it is supposed to be until the distributor. Just hard for me to believe that by chance that is when it went. Ordering the parts today to rebuild and hopefully no more issues for at least a little bit so I can enjoy driving it some.

 

Not in a 67 Coronet with a stock dizzy

 

Mallory... I must have missed that part....lol

 

Some coils have a metal crimp not far below the terminals. Is it possible you moved/ bent one of the terminals and shorted one of the coil connections to that crimp?

You have a Unilite and no other box, like MSD?

For a temporary test either clip a meter / test lamp to first one and then the other side of the ballast, crank the engine and see if you have power

Clip the meter to the coil NEG terminal and crank, see if you get a "flashing" lamp or "bouncy" meter read.

Remove the coil wire at the coil. Check for spark at the coil with a grounded clip lead and probe. You must crank WITH THE KEY for this test, or by jumpering across the ballast, AND temporarily feeding power to the coil + with a clip lead. Do not leave this hooked up longer than needed to test.

(You can buy "made" spark test tools for this job)

It is NOT advisable to allow sparking from the coil with nothing hooked up, IE 1 or more disconnected plug wires. This WILL kill ALL electronic ignition modules, and is mentioned in just about every modern shop manual.

 

Some how that post wasn't there when I post it as a stock dizzy... My Bad... Sorry bremereric...Bill
