My thoughts exactly, multimeter ftw. Test lights are fine on old-tech but for anything like the Supra with ECU controlled circuits a multimeter is a must, can do a lot of damage with a test lamp & an ECU!!! Oh & plug everything back in now too, if it runs sometimes then whatever is causing the fault can't really be a short or you'd be blowing fuses, flattening batteries overnight or starting fires...
tbh the intermittent bit does sound like possibly a relay or bad connection, do you have a spark when it's cranking but no-go? this will at least tell you which side to be looking for the fault rather than trying to trace back from the ign. switch loom.
