Hei conversion Intermittent start?

Update:

I ruled out some things tonight. I decided to take Bill's suggestion of a jumper wire, but go several steps further and remove the ignition system from the factory wiring. Ran the necessary jumpers so the coil, dist & hei were hooked up to the appropriate ground/12v. The car fired right up. So now I know those 3 items are not an issue.

So now the plan for tomorrow(if i can find time) is to try and re-integrate the ignition system removing one jumper at a time.

Would've done it tonight, but Side exhaust at 11pm doesnt make the neighbors happy.
