Narrowing down my ignition problem. Might be something oddball..., anyone recognize this alarm? Options

[billh1963]

Using suggestions from several people on the board much smarter than I am, I have verified that there is no spark coming from the coil. I have changed the coil to a known good coil (and coil wire from coil to cap) and still nothing.

The electronic ignition is sending an alternating signal of some kind to the negative side of the coil....which I believe it should be doing.

So, before I start messing with the distributor (since the car was running fine and just stopped suddenly) I am wondering if the issue is related to the alarm?

This car has an alarm system from Direct Electronics (they have multiple brands including Viper). Does anyone recognize it? Yes...it's dusty from sitting behind the console.

It seems to work. Pressing the remote activates it. However, when I deactivate it, the green light on the receiver box blinks momentarily and then the red light comes on (as seen in the picture). I'm wondering if the alarm is not fully deactivating? I assume that in addition to honking horn, triggering alarms, etc. part of the function of the alarm is to deactivate the ignition? Thoughts?
