no crank no start troubleshooting

Car:1994 NG900 2.0 turbo manual transmission
First here's how the problem was discovered:

Coming out of grocery store, turned key and nothing happened (except a single click), tried again and as I so happened to hold the key in the ignition position longer the car did start up after a delay. Drove home. Now the car will not start. all that happens is a single audible click.

since then I have performed the following:

-Swapped in a known good battery. problem persisted
-new ignition switch. problem persisted
-swapped known good starter. problem persisted
-swapped known good negative battery cable. problem persisted
-checked to make sure motor was not frozen. was able to turn crank no problem
-swapped known good positive battery cable...

after I swapped the positive battery cable, the results were mostly the same except a few times it clicked 2 or 3 times very slowly- could've been from moving the crank/flywheel?. And Afterwards I noticed a faint burning smell.

note: I have no ground cable going from the transmission to the car body. Never have, in fact I see where it gets grounded to on the body of my '98 ng900 but my '94 doesn't even have that threaded post there. I have never had any problems with starting the car in the 8 years/60k miles that I've owned this car. The car is pretty clean with very little corrosion anywhere.

Also I rebuilt the engine 500 miles ago. At approx. 250 miles after the rebuild the car died while I was decelerating and I towed it home. Car would crank but not start. I swapped in a good DIC and it started right up fine. This seems unrelated but who knows. The next 250 miles after that went completely fine until the grocery store incident.

I guess the next steps (or should've been the first) are to check voltages but I will have to go out and buy a voltage meter. And I will need some guidance through these steps as I've never really done that kind of diagnostics work before.

So... I'm on my way to buy a voltage meter now. What's next? Does anyone have any suspicions? Anything about this sound familiar to anyone?
