I agree about the polarity of the crank trigger wires. I've seen it and fixed it before.

I think that box has to have "0" degree retard chips when no retard being used.

YEP, had a freind 2 weeks ago was about to load up after trying everything he had, motor just didn't sound right either. So I asked him what have you done...he said nothing just pulled this chip out cause I didn't need it, he put it in FIXED. Those units require a chip in each position always.

All 4 retard inputs must also be grounded besides having the zero pill in if the retard is not being used.
I'd check that ground .

I had the same problem. Take these chips out and do a OHM test with a multimeter. They should have 0.00 ohms. Regardless, if not using high speed timing control, throw these chips away altogether and ground the Timing #1, #2, #3, #4 terminals on the side of the box. Daisy chain three of the them and then run to a good ground. I had this same problem.
