checked all fuses and relays. all good. connections were dry and tight. i have fire all the way to the starter. its the original starter. the only thing that is makin me think is the damn security light flashing so much. i dont understand why it would be doin that.
if the security light is on, unlock and lock the car. Wait approx 30 minutes and try again. If it still doesnt work, unhooking the battery should do the trick. I had this happen to me alot and it got really annoying.

well thanks to all the help i narrowed it down to the ignition lock cylinder. cause i locked the doors then unlocked them with the key and it wouldn't recognize my key so the alarm went off. im gonna bypass it.
correct me if im wrong. get a resistance reading on the keys pellet then unplug the lock cylinder and put a resistor with the same resistance as key into the connection? wouldn't it have a wrong reading on the key if the car wont recognize it anyway?

If the key is giving you a false ohm value and you put a bypass
resister of the same ohm reading on the connectors, then its not going
to work. GM has several different ohm values for our keys. I had to get
an extra key with a 10K reading if I remember correctly.
On the flip side, if the key is reading one of GM's specified ohm values
than maybe the key isn't making good contact. If that's the case a bypass
resistor would be a good approach. If you are putting the right ohm value
and the car still doesn't start, it would lead one to believe that maybe
the ECU isn't reading the ohm values correctly.
