Need firing help

[wildcard]

This is probably gonna get complicated so bear with me. My 71 300 I6 started trying to die when coming to a stop this evening. Then it started dying at stop signs. When I got home, it wouldn't even idle. But it always fired right back up on the first turnover. Out on the road or sitting with my foot on the gas, it ran fine.
Got home and put a new dizzy cap, points and rotor. I know I should have changed the condenser but I didn't.
After putting new parts on, it started a few times but still wouldn't idle and had a miss. I've pulled #1 and checked the timing and that all seemed OK.
Now, it turns over good but won't fire at all. I put the timing light on and had my wife try starting it. No fire to plug. Tried on a couple other wires and still no fire. Checked timing light on wifes car. Works fine.
Then I put the old dizzy cap and rotor back on, still nothing. Pulled the cap and rotor and turned it over to discover the points aren't getting fire.
So I need some advice as to what the problem could be. I plan on changing the condenser tomorrow. Could it be that or the coil or do I need to look elsewhere ? Really have to get it going before I do more damage than the truck is worth.

check the condensor and points for a good ground. my truck did that no fire to the points and the screw for the condensor was rusty or soemthing. i got it cleaned up and put back and i had fire at the points again. but you could have a bad coil too. make sure you have power to the coil. then check the coil.

Got the condensor, plugs and wires replaced today . Even took it to a mechanic shop. No help there.
It was running like it was out of time. So I pulled the dist. and reset it. Doesn't look like it moved any after getting it back in. But it runs good again.
Thanks for the reply and advice fordman.
