It was there, however after the car stoped trying to turn over I checked again, and I have no spark now. I was thinking of replacing the coil and the ballast resistor as I do not know how old either is. Is that a good place to start? I checked all the connecitons already. TIA!

Make sure the ECU has a good ground and then maybe pick up a cheap one for 15$ at a parts store if it still doesn't work. Hope this saves you some aggrevation. BTW, my box passed all the "tests" that were in the Hayne's manual but was still bad. It's usually a good idea to have an extra ECU around anyways.

When ever you have trouble with spark, even if changing the ECU box fixes the issue check the reluctor gap in the distributor (0.008-0.012 IIRC) with a brass feeler gauge. I have had intermitant spark due to a larger gap. I have also witnessed a guy who would swap between 2 coils to get the car going again when it was warm....same issue, I told him to check his reluctor gap and that fixed it
