VATS problems - symptoms

I've got a 91 Formula that I'm trying to get running. I got it as a non-runner so I've never seen it even turn over - I've tried cranking it but it does NOTHING. The key turns everything on, but when you go to start it, nothing happens, no click, no sound, nothing. Just for good measure, I did check the starter and everything appears to be hooked up correctly.

Is that a symptom of a VATS problem? I've never had to deal with a VATS issue on any of my five thirdgens that had it, so I'm kinda lost. I just don't know if I need to start there or if its even a symptom of a VATS failure.

Well, its not a VATS problem... The battery had enough juice to power most everything in the car, but not enough to even attempt to click the starter over. A battery with a full charge and the engine turned over.

Anyhoo - In the event I did have a problem, what are the symptoms of a VATS failure?

nothing hapens when you go to start Vats is basically a starter kill relay if it does happen its normally contacts on the key and cylinder getting dirty contact cleaner in the cylinder and key is normally a good place to start just make sure your battery is disconnected and wait a long time for it to dry

VATS also takes out the fuel injectors so even if you hot wire the starter to crank the engine ,it will still not fire up
