Default RANDOM no spark / start 1993 Toyota Camry 2.2

My 1993 Toyota Camry 2.2L has an intermittent, no spark / start problem.
Sometime it starts and runs with no problem, other times it will crank with
no spark at all.

I've seen more than once when I use a spark tool to "see" if there's spark,
it will change from no spark to full and the car will start right up.

I've tried wiggling wires, bench tested all components by the manual etc.
etc.

I even stopped by the Toyota dealer for some insight and they agreed that
the car must stay "broken" long enough to diagnose. Just a few minutes ago,
I pushed it into the garage, put it on the lift and it started right up.

I have replaced the distributor/coil assembly (new unit), ignitor, ECM,
charcoal canister and spark plugs to no avail.

ANY ideas would be greatly appreciated.

I've seen similar problems if an engine ground strap, or other grounding
connection in the circuits, is faulty. Have you checked that the
strap(s) are okay, and the contact points clean?

The ground at the transaxle/engine was a little "iffy" and it's spotless
now. I does start up now and I'll keep checking it...

*Thanks

Did you replace plug wires, do all plug wires show no spark. Is this the
reason you replaced the coil?

I didn't replace the plug wires as they are either all firing or non firing.

Did you use toyota parts, is this the reason you replaced the coil,
coils are known camry issues and aftermarket electronics have a high
defect rate.

So far so good Larry - I think your ground suggestion nailed it.

===============
So where did you find the questionable ground?
Battery?
Frame?

There's two grounds that leave the battery. One runs to the body (and was
OK).

The one that grounds the engine is on the transmission. It was the
questionable one and the car is still running fine.
