Power to the coil but no spark.

I am using the key twist to start. I disconnected the top of the distributor from where the coil tower connects and used the end as a test gap. My test today ended up as an inconsistent thin white spark approx 1/2 inch long.

Then I would monitor the coil positive with a meter, or jumper power direct from battery and retest

It pretty much has to be (in no order)

1...Low voltage/ poor connections in harness to coil+ or module
2...bad coil
3..or bad module or POORLY GROUNDED module
