No spark at coil

A little background on the car.... it's been sitting for about a year and a half now. I've been through everything in preparation of starting the car.... new oil, new filters, removed old fuel and refueled. I also removed the intake manifold to fix the rear oil leak.

I mention these things, not because they pertain to the problem but just to let everyone know that.... the car was starting and running fine prior to this new problem. Newer Opti has ~1500 miles on it.

Now the problem... no spark at the coil. I'm not an electrical guy but here's what I've done to check. Did a visual inspection... pulling the lead wire (going to Opti) and checking for spark. Nothing.

Checked voltage (DC) at the connector. Now, I'm kinda lost when it comes to this type of thing but this is what I did... turn ignition to "On" position, read voltage (DC) with a multi-meter set to "20". My reading was .12.

I'm hoping that someone might be able to point me in the right direction so I can resolve this problem. I DID remove the coil and even did a swap.... trying to see if maybe it was a dead coil. Coil is good as is the control module, which was checked by two different Autozones. Everything, "Checks within specifications".

I'm lost here...... thanks.

.12 and not 12, that means that you have no power to your coil or icm
