Id look for some broken gear teeth or something like that. Had that happen on old Nissan truck once. I was out of state traveling, and timing gear went causing engine damage. After doing an engine swapout, found the new engine had a few teeth on flywheel were missing. Starter spun occasionally. Every other start, I had to push and pop clutch. I was a couple of states away, so could not go back to repair shop either.
Thanks for info about location of starter on Norstar, I feel better about keeping this 94 Cadillac now.

Re: bench test a starter?
Now that I think about it some more, I think Zonie is on to something. That is the only explanation I can think of. Actually I thought about it yesterday but did not want to mention it because my wifes '96 Bonneville had the pinion cluthch go bad and boy did it screech. I pulled the starter and had a new clutch put in for $25 at a local starter/alternator rebuilder.
If the starter motor spins up and the pinion does not extend to the end of the shaft and engage the flywheel then you probably have an open winding in the starter solenoid. The electromagnet is not pulling the plunger bad to engage the bendix into the flywheel teeth.
Either that or the flywheel teeth are missing.
Bench testing a starter is okay but it's not under a load.
If the solenoid is bad, I'd recommend replacing the whole unit as an assembly.
No sense in putting a new solenoid on a worn down motor.
Just means you'll be taking the thing off again when the motor goes bad.
