Injectors not firing

[taika36]

I have a 1987 toyota supra, turbo, i rebuilt it, couldnt get it started without dumping gas in it myself, come to find out injectors arent firing. Have had it with a family friend mechanic for about a year and he cant seem to figure out the issue, he recently told me he found out its a security module under the driver side dash, and the module is missing, i cant find any info on this at all to see if this could be the issue or not. I found a theft waring module online that may be what hes talking about but i have no idea what it looks like nor does he, if anyone has any info on this i would appreciate it, thanks.
