Spark coil to dist, but not dist to wire. Sounds like it's grounding out somewhere. Might be a bad cap/rotor. Off brands seem to live short lives in these vans.

I've seen off brand rotors glaze at the contact point from the coil wire..try lightly sanding the contact point with fine sandpaper, if it fixes it, replace it with a Delco part. (Don't keep driving it like that because it'll do it again)
Figure out the problem before buying parts

:rockon: I was getting fired out of my coil, but decided to pull off the coil, dang that was fun took some reading on the coil and it was weak, got a new one and made sure it was grounded good. Put it back together turn on the key fired right up. Thanks for all the input..
