Passlock problem with 97 Sunfire

I did that too (I actually used a pair of alligator clip leads but I don't think they add any resistance (maybe an ohm or two?)

I'll give that a shot.  Up until this week I didn't know anything about these bypass devices so I just assumed a device that could learn resistances would be pricey, I'm assuming you're talking American dollars but that's still not too bad.  I called a shop and he was reading me right out of the GM service manual what I should do, he said to clear a 'hard code' leave the key in 10 minutes until the anti-theft light stops flashing, only trouble is, mine stops flashing after about 10 seconds.  He figures my only option is to bring it in and get the codes read, does anybody have any experience with the units you can buy at Wal-Mart?  Are they worth anything?  I was thinking of giving it a shot and then bringing it back if it's useless (if they'll accept a return on it).

Ok, I've tried every suggestion here and so far no luck, but something I just found out is that if I turn the key to the forward 'acc' position insted of the furthest forward 'run' (right before crank) AFTER stalling the car, the alarm flashes indefinately.  If I leave the car in 'run' after it stalls, it quits flashing after about 5 - 10 seconds.  According to the GM service manual (and some of the posts here), if I tripped a hard tamper code, the anti theft warning should flash for at least 10 min before going solid.  I just got finished trying to wire up a Bulldog Security bypass module that I found for 30 bucks (Cdn) at Walmart when I noticed this, so tomorrow I'm going to try soldering all the wires I've cut (I accidentally cut the bulb test trying to tap into it) and leave the key in the 'acc' position after stalling it.  The weird thing is that the alarm only flashes in this key position after the car stalls.  Thanks again for everybodys input.

Just wanted to post a thanks to everybody that replied and offered their help.  Unfortunately the problem was the PCM and I had to get it flashed.  The only thing I can think that I did was mistakenly hooking up the alarm wire off the remote starter into the fuse slot for the alarm.  The shop that did it for me had no idea what caused it, and didn't know if my screwup was the cause but they suggested I disconnect my battery before trying again, contrary to what the instructions for my remote starter said.
