Wow. lots of information to process.
The distributor on the T3 is a Hall effect type.
None of the 28 pins used in the T3 ECU is for serial data. The car has a 4 pin Monitor Coupler. Connecting the pins B & C enable Diagnostic Mode by connecting a ground path to the diagnostic request signal wire from the ECU and the CEL light flashes any codes. The other 2 pins go to the DNL lamp located in the instrument cluster and the Test Switch Signal on the ECU. The T3 does not have the extra Duty Output Terminal or the Diagnostic Output Terminal of later cars. So this means no serial data access from the factory is available without finding the serial pin inside the ECU I guess..
We will try to check for spark at the coil next, as well as check whether the CMP is working.
I have found a portable handheld oscilloscope similar to the input voltage rating spec you recommended. (Unfortunately ebay does not sell the one you suggested anymore). The one I am considering has an x10 probe rated at 400DCVmax. (single channel).
