PCM Testing? I have a box of spare parts in my closet that came with my car, and have a spare PCM. Is there any way to have it tested to see if its any good? I was thinking of sending this one away to have tuned while I do a few modifications, but don't want to bother if its junk. I'm not sure why the old owner would have had a spare 
Part # on the outside of it by chance? Hard to test one of these but you might find out its origin. Could be a spare the previous owner bought so he/she could swap tunes with a wrench. Let's see if its GM part # identifies the year it's for (maybe not necessesarily for a 95, could be for a 94). Hell, you might even open it to make sure there's not anything obviously burnt/ shorted on any of the PCBs before you consider further investigation...

The boyfriend has a multimeter (or something like that) that he was planning to teach me to use this weekend so I can check some other stuff on the car, would that work for this as well?
Sorry for all the stupid questions, still trying to learn here!

you can take it to a dealership and they have some rig that will test it. they did one for me and then threatened to charge $400 to have it flashed with a stock tune. one of the local tuners made one out of an old engine harness and a computer power supply but i havent seen it in years since he moved on to LS based cars.
yes a multimeter will work of you can figure out what the ohm reading will be. ohm is the resistance the the wire carries. And NO question is a stupid question we are all here to learn and i will share as much information as i can with everyone

Well I got lucky. I'm a service writer at a small shop, and we deal with the local Pontiac/GM dealership a fair bit for parts. I called and talked to the guy I usually our parts through and mentioned this, and he said he'll have one of the techs test it and put a stock tune on it for free. If it turns out to be in decent condition, I'll send it off to be tuned somewhere (any suggestions?) and keep the current computer in my car for now while I'm doing some work on it, so I can still drive the car around the yard when I need to.
Sounds like you're in good hands with the test. If you can get it somewhere for a dyno tune, you might have it programmed for a very agressive setup, maybe too much advance, etc. for street use but have extra hot for strip runs. Then drop the other streetable PCM one in and drive 'er home... have fun with it.
