MS2 installed, wouldn't start, then it stopped cranking?
I tried to install my new to me DIYPNP. Got everything connected, removed the ST fuse, then hooked up my laptop. Everything connected just fine and I loaded the 90-93 Miata basemap straight from diyautotune's website. I set the timing to 10* fixed in Megasquirt. The CAS timing was set to about 16* but when it started, I was going to bring it down to 10*. The car would crank, but wouldn't start. I tried a few times and nothing happened. I looked at a couple other settings, but didn't do anything but switch from "Use Table" to "Fixed Timing" in the ignition options. After about 10-15 minutes of looking at stuff and cranking here and there, the starter stopped. When turning the key, it would click once as if the battery was dead. I put a charger on it for a bit but nothing changed. I took a look at the starter itself and nothing appeared out of the ordinary. I fiddled around a little longer and decided to just plug the stock ecu and fuse back in. It still did not crank. Just simply clicked once.
My car is a stock 91 1.6 Miata (It has a header, exhaust, and cone filter, but that shouldn't effect much. Does anyone know where to "start" with this? I just changed the battery and starter about 1-2 months ago so I have a feeling there shouldn't be any issues with either.
Sorry if there is another thread with this issue. I did some searches and I might not have the right keywords.

If it helps, I still have all the stock sensors and such. When loading the tune in, I did select narrowband for the o2 sensor. If needed I can upload a log / tune, but I figured it wouldn't be necessary as it's a straight basemap file from their website. I'm not worried for the car not starting as I can figure that out eventually. I just can't do anything if it doesn't even crank..!

News Update:
I left my car on a 40A charger for a good 40 minutes. I tried to start it and still just a single click. I then decided to pop start it by rolling it down my driveway. The only thing that I accomplished was getting my car further away from my garage. I’m not sure if it was going fast enough, but I’ve pop started it with my driveway multiple times in the past.
So unless my 2 month old starter went bad, is there any other advice I could get from anyone?

Not a dumb question. I never removed it. I was trying to get the car started on Megasquirt with all the stock sensors, including the flappy door AFM. So yes it’s still connected and installed.

Loose cables? I would pull the battery and have it tested so you can rule it out, the battery in my golf went flat dead to the point where it wouldn't even hold enough charge to be able to restart even after being run a while. It showed no signs of going out, just one day, totally fried.
I drove it every day for a week then also pulled it into the driveway to swap the ECU. Everything was working perfectly fine.
If the battery test comes back good, I have another starter I’ll throw in. If the battery is shot, I’ll just swap out the battery.
if not, I guess I’ll go hunting for some messed up wires somewhere. Hopefully its simple!

Issue has been resolved! Update for anyone in the future that needs another resource for this problem.
I removed the battery terminals and connected it straight to my other car’s battery with jumper cables (completely disconnecting the battery in question) and it still clicked.
I decided to stop wasting time with the battery and move to the starter. I had another shipped to me overnight and swapped it out in less than an hour. Connected the battery back up and it fired up instantly.
Just because a starter in new doesnt mean you should rule it out an an issue.
Now to figure out why it wouldn’t start on Megasquirt!
