ISO: A/C vacuum hose that goes from compressor low pressure / vacuum side toward evaporator  

I'm finally getting car ready to go! https://www.instagram.com/reel/Cb5q6jHAH7n/?igshid=YmMyMTA2M2Y=

1983 Mitsubishi Starion Still trying to work through various electrical gremlins and can't seem to get spark. Air, fuel, and compression is all good. Just replaced the ignition coil and still nothing. Fusible links for Ignition Switch and ECI are good. Pickup coil has good resistance. Hoping it's just the distributor cap and rotor, but I need confirmation. How can I test the ESC Igniter (ignition control module) before I buy a new one? Is there anything else it could be?

The passenger side is working intermittently, driver side is normal. where should I start? Any help would be appriciated.   Thanks
