I have a 1990 Subaru loyale with a no start no spark I’ve replaced ignition distributor made sure it is properly wired the only thing is the ignition pulse if I’ve done the test right with a test light. there is no pulse. There is also other random stuff that doesn’t work on the car , lights, dash light etc. I wondering if it is infact the ecu that isn’t working and if not other things it would be
side note there is no check engine light or codes
