More ignition issues on the dart

if you can take your pickup back..by all means do it...but handy to have a spare. Trying tpo help remotely all we can do is suggest things from our own experiance... having had picksups go bad....and i'll guess at the junction between lead wires and the tiny coil....well you can see why they are sometimes the cause.

1 last thing as the whole lot all seems to work in isoltation (obvioulsy can't really test the igntion box)

try undoing, cleaning up with a wire brush and re doing up your engine to chassis earth strap...... couple of spikey washers and some grease on it will see it good for the next 50 years.. :)
this is an area thatb can just go bad usually after a transition from hot dry to cold wet weather or indeed humid to dry.. anything that has an impact on corrosion of the rust (brown) or verdigris (green and white) nature

resistance here will mess with everything.....

if there is a problem and you fix it you starter will spin faster as well...
Thanks. Seeing how I don’t have anything left to check, I’ll do that when I get home. I overlooked the ground because generally in my experience a bad ground causes it to not even turn over. And it still turns over at normal speed. But I’ll recheck the ground both on the block and to the core support. Like I said, I’ve got nothing better to check at this point. Also, I don’t have a tachometer, but that’s a useful tidbit of information to keep in mind. If nothing else, I’ll try and put together a video of everything that it does (and doesn’t do) this weekend when I’m off work cause as it sits even on a day shift there’s only a less-than-half hour period between the end of my shift and sunset.
