2001 Blazer Bcm Issues

[midnightbluS10]

So I work at a GM dealership. During some down time, I attempted to update my bcm in my 2001 Blazer. It's a donor bcm from a 2000 Jimmy with keyless entry. When I got done, it was showing code P1626 theft detterent fuel cutoff or something. I attempted to do the VTD programming with no success and now my truck will not start with that bcm installed. Am I screwed? Can I "unlock" that bcm somehow? Thanks.

Starts for 2 seconds, & immediately stalls with security light blinking? Check that fuse in the under hood fuse box.

I ended up leaving it overnight and bringing my original bcm to work the next day. Swapped it in and it fired right up.
