Anit theft light is on

I have a 96 Z24 that I Changed the engine. I bought the car for 100 not running had thrown a rod. Now I have it back together and the anit theft light is on solid . I checked the injectors are not fireing i believe it is the anti theft causeing this problem how do i get around it or fix it. I have fuel pressure and the engine rolls over i do not know how you would check for spark but i believe that no injector fire and spark will be related.Please help I an bout ready to pull out my hair and I am bald (by choice):smokin:

did you try simply pulling the fuse for the theft system?

I dont see a fuse marked for the OEM anti theft

it'd be with the fuses under the hood, is there where you looked?

I looked there is no fuse for the anit theft under the hood or in the drivers compantment. Why would the OEM install a fuse that can be removed easy to disable the anti theft anyway. Could the car if it had a key fob at one time and the alarm was set and now i dotn have the fob be the problem?

I had to have mine towed to the dealer to be reset. I tried disconnecting the battery & all sorts of neat ignition switch cycling with no luck. I set the thing off while changing the instrument cluster (hit the radio power by mistake with the cluster out). Probably didn't need to replace the cluster either. Had no daytime running lights, GM said the problem was the cluster.
