I would check power/ground and activation signal to the injectors. I can’t think of anything in ISTA/INPA that would disable them in any way short of coding the car.
When the DME doesn’t like something and it wants to disable the vehicle it won’t provide spark so I’m not what you have going on there

The first step would be to buy a cable from Amazon and download/pay for ISTA. There’s plenty of people here that can point you in the correct direction for download links. I personally can’t for a variety of reasons but if you want to work on this car this is the most important and informative tool available.

Great, then Pull up wiring diagram for injectors and test power/ground/signal at each injector. Read the functional description and maybe run a power supply test plan on the injectors as well.
