Spark issues... Won't start (72 w/ ZX dizzy)

[e_racer1999]

We had the car running before we pulled the engine to replace a gasket and the cam. Today, after reinstalling, the car won't start. After cranking, it seems like it wants to start for a couple seconds. We pulled a plug and tried to get it to spark (after confirming we had fuel), but it didn't spark until AFTER we let off cranking.

I plan on installing a spare points dizzy to see if somehow the ignition module was damaged, but we've done a lot of wire elimination earlier. Basically, the only wires to the interior go to the ignition switch and the tach. Again, the car started with the same setup previously; the only known change was a new gasket and cam.

If anyone has any input or ideas, please let me know where to start looking, as electrical is not my forte.

Could you have hooked up the two wires to the ignition module backwards?

The negative side of the coil goes to the terminal that forms the "top" of the T formation, and the positive side goes to the "post" of the T. If you had them backwards the coil would only fire when you turned the ignition off I think.

I am going to assume that you have checked that the plug wires are all in the right place and all of that.

Triple checked the plug wires. I tried wiring the E12-80 both ways; no dice. Tried the points dizzy I had, no spark.

Did a couple tests with a multimeter, though. found that both sides of the ignition coil are receiving a (+) 12V to both wires that terminate at the coil (?), so I'm thinking there's a short somewhere, unless that's how it's supposed to be

Wish I could help, but I too am having the same problem now.
