No spark

Update..
I cleaned ecu plug connection.
With key on there is power to the positive side of coil.
When cranking there is power to negative side of coil...
When I mean power ..checked using test light
OK look, this here is a two way street. Please do as I asked you and post back the results. You are not looking just to see if there is power here and there ---you are looking for specific measurements. Re-read my post. Here is what you are after.

The coil may not be drawing current through the ECU. This could be because the ECU is bad, or NOT GROUNDED, or a bad connection in that cruddy looking connector.

So one more time

Turn key to run. MEASURE coil + voltage. You do NOT want the reading to be full battery voltage, because this would mean that the coil is not drawing current.

Coil NEG---Coil neg should read quite LOW, probably no more than 2V or so. If it reads battery voltage or much higher than 2V it indicates coil is not drawing current.

Did you do the tap test?

Otherwise some of us here are just wasting our time. We are glad to help but YOU need to listen and you need to respond.

You showed the gap. You need to measure it. Get yourself a brass feeler gauge. Last I knew, Oh'Really's sold them but you have to ask for them and maybe order them. Sometimes you get lucky and a set of feeler gauges will have one or two or three in there that are brass in the range you need. I've forgotten the spec it's in the service manuals. .008" I think, that is inches not metric.
