Hei conversion Intermittent start?

magnumdust said

I did use a heatsink compound and yeah it does get warm quick when it runs, but prior to the engine running there doesnt seem to be any heat on it.

Ok, that rules that out.

I was able to get the car to start with the 12v/12vbypass wire earlier today and found that it wouldnt start with the longer dist. pickup wires. Only with the shorter ones i had. Still wont start reliably.(1/10 cranks give/take

You might try twisting the wires coming from the pickup. When I worked on electric forklifts every once in a while we'd run into one doing crazy things and someone discovered by accident that if we twisted the wires coming from the heat sensor it'd straighten it out. We figured it was picking up RF interference. I know it's a different component in your case but a pickup coil can pickup RF so it's possible and an easy test.
