    Default 99 suburban computer swap now it wont run

    Hi, swapped computers and the truck starts for a second then dies. I heard that it may be the security system. Anything I can do to defeat it or does it need to be reprogrammed?

    It sounds like what happens when a remote starter is installed without the proper security bypass. I don't know how you would go about bypassing it now. Maybe a bypass from an alarm/remote start system, wired properly, can bypass it for you.
