No spark or fuel in my 96 Miata.
Mechanical timing is fine, car runs now...on starting fluid. Diagnosing fuel issues now, about to replace my injectors. I still have no idea why the ignition system started working.
Yeah that's my best guess too. I swapped in known good injectors and I'm still not getting fuel, I'm actually starting to suspect my new Walbro fuel pump. I'm gonna swap in the stocker from the parts car tomorrow or monday and go from there.
At least I'm only chasing one thing, chasing both spark and fuel was a nightmare.

It's running but it's making zero noise and I don't think much pressure. I actually commented on how quiet it was, I ran a Walbro 255 on my Grand National and you could hear it over the open exhaust when I had the cutout open.
Maybe I just missed it like I missed where you put the year of the car, but I didn't see where you actually mentioned replacing the in line filter. Dropping and swapping the tank, new pump, and new sock were definitely needed (that **** looked like the Titanic wreckage), but certainly the in line filter should be changed too. Probably has something to do with the weak pump if you actually haven't changed it.

Have you tried pinching off the return line temporarily to see if the pump can build the pressure at all? If it can, maybe it's the regulator. I also think you should be able to hear that pump though.
I just swapped in the stock pump out of the parts car and it kinda runs now. It won't idle, but it's been sitting forever so I didn't expect it to be perfect. I'm gonna get it running and idling, starting with new spark plugs, then maybe try the walbro again just to be sure, but I think that was my fuel issue.
