Have I managed to get the wrong distributor cap & rotor arm?
It has always been an issue trying to get the right parts for this car, any other Sport owners had a similar issue with finding parts or more importantly the right parts.

Can’t say I’m 100% familiar with the pre-facelift sport, but might be worth checking the wiring to the hall sender at the side of the distributor, and also checking the integrity of the wiring to the coil... I know from experiencing something similar to what you describe, being caused by hidden broken wires at the connectors.
Also, have a look under the dash (again not 100% sure on your year of 80), but behind the dash at the drivers side you will likely find an ignition control module, check the wires to this and it’s condition (it sits on a metal heat sink).
Daft question, but do you ever recall seeing a very slight (very slight) jump/pulse in the rev counter when the ignition is initially turned? Mine has always done it, I’m not sure if they all do? When I had a similar issue this stopped happening and I got no spark, as soon as I fixed the aforementioned broken wires it began again and the car fired without issue - like I say I’m not sure if they all do it, but that would be a good signal and point towards a hall sender/coil/ICM/wire issue.
Hope that is of some use to you, frustrating I know, but it’s often just working through each part methodically, trouble is it often involves buying surplus bits until you find the problem... not like these things are at scrap yards anymore unfortunately.
