Default ls-v swap runs on obd2b but not obd2a????

my car has been running and obd2b engine harness to a jumper harness to run an obd2a ecu for the past 2 years ever since i got the car. recently i swapped the ls head to a gsr and it ran no problem for 3 days and then it crapped out. after checking a couple of things, the car will only run on a obd2b ecu the jumper harness i had in there is still good no loose wires/pins or anything. even went to rywire to get a obd2b to obd1 jumper harness and chipped p28ecu and the car still doesn't run. anybody have any clues as to why this is happening?

What OBD2B ECU are you trying to use?

As of right now it's running on a manual crv ecu without any problems. But the car itself won't run on any obd1 or obd2a ecu with the correct ecu jumper harness
