ignition problems
ok...it's not a truck, but it's all the same....vehicle of concern is a 68 mustang with a 289....i neglected to tune it for the past 3 1/2 years because it runs great...but monday, i got new: plugs, accel wires, blue streak cap & rotor and points/condenser and accel coil....problem...it ran monday night BEAUTIFULLY....yesterday, i went to start it and it started normally, but when i went to go somewhere, it got really jumpy...i pulled into a 7-11 to check it out...it was missing really badly....so i pulled out the timing light, and it kept cutting out, telling me that it wasn't firing consistently...si i investigated...rechecked everything, and found that the batt and primary wire on the coil werer hard as rocks and the ground in the dist was questionable....so i ran a wire from 12v source to batt on the coil and one from the points to the coil and one from the points base to a ground...still kept cutting out....so i reverted back to all the old stuff from before the tuneup and no change..............when it does fire, it is right on time, too....
any ideas????
sorry for the length

New Coils can become subject to intermittent failure.
Did you test the Vacuum Advance Diaphragm for seizure ?
Did you grease the cam inside the distributor ?
Did the points adjustment screw become stripped ?
Blue Streak Dist.Caps are Garbage !
I have absolutely NO problems with my 289 68-Mustang.

Rw,
If she just went south on you and stayed there go after your points. If you run a hot coil with a 12v source you can burn up points very quickly as in one day.
Secondly, a rare failure that can drive us to drink is the condenser. It's really not a condenser, it's a capacitor. There difficult to diagnosis and cheap to replace, so do it. They usually show there flaw only at temp.
You said ignition; so stick with you diagnosis and don't go messing with the carb. Change one thing at a time and you'll figure it out in time.
Good Luck, Have Fun
