slant six starting problems

So here is the latest. I checked the connections at the coil and at the ECU for corrosion and cleaned it all and put it back together. Tested the ciol for voltage and got 1.4 volts AC. Tested the negative side of the coil for spark with the key on and got a spark on and off when I put it to ground. I checked the reluctor for gap and adjusted from .010 to .008. Checked the distributor for rust or damage everything looks good. I do have a small amount of side to side play.
Checked the negative wire from the ECU to the distributor with an ohm meter and tested good with each end removed.
Any ideas? I think I have covered what has been suggested.

Thanks again.
