Hei conversion Intermittent start?

Looking at the pics, a couple of observations:

1. The wires from the distributor are threaded through the HEI spades. The signal from the distributor is very weak, and could be missed by the HEI if not securely connected. (not an issue in the first pics you had)

2. The wires from the Distributor could have a stray strand that could ground the signal to the mounting strap, losing the signal. (not an issue in the first pics you had)

3. The Coil is not plugged in. :)

4. Disconnect the blue and brown wire from the coil, making sure they don't ground out on the car body! Wire a hot wire from the battery directly to the coil in their place.

5, What is the voltage to the blue/brown wire when the ignition is in the run position? What about when the engine is cranking?

6. What is the battery voltage when everything is off? What about when the engine is cranking?

If the connections are all secure (not as in the picture) and the HEI is good, it should fire.

BTW, HEI's are VERY easy to fry with loose or backwards connections. No need to ask me how I know...

The HEI like a lot of voltage, minimum 11+
