That reminds me of 1974 seat belt no start switch that Mopar had. Every new car we sold that was the first thing disconnected.
THEN the key in buzzer !!
The district Mopar rep told us to use Freon to get cars started. Take a can on the road call and freeze the ECU.
Car would start and bring it back to the dealership for a replacement ECU.Freon was about 50 cents a can back then.
