security light needs to be on during the learn procedure, its always 10minutes x 3 rounds, it may be a different system passlock/passkey/etc
one thing you can do is on your original PCM, look for a dark blue wire used to go insid ethe car, then go on ebay and get a 30/50 hz ground pulse simulator and wire it up to trigger the passlock (the disable signal is a 30 or 50 hz grouind pulsed signal present only during cranking)
when the pcm see's it your good to go and it wont kill it.
the benefit of this is that you can kill the starter power feed to it and have the system enabled as a theft deterent
