CDI/Tachometer disconnect now starts

Hello all,

I had a few questions I thought you could help with.

My 89 930 had an intermit start problem. This was both hot and cold and happened at random times.

I listened for the whining sound at the CDI, however, there was none. I read at (this is the unit that is there) that they do not whine.

I had no spark at the plug..dist...etc...

The harness going to the CDI had a voltage of 7.5V. The car had 12V at the battery.

Anyways, I disconnected the tach plug by the o2 sensor....AND IT STARTED! plugged it back....and no start.

THIS is the problem, but I am not sure from here. Is this a problem with the Tachometer itself or the wire leaving the distributor to the CDI? The car will run now but I have no tach.

If anyone has been there...done that... please let me know. I did not see anything with my search.
