That was a robot, just ignore it now.

Check the fuses for the ecm/pcm. One second and I'll tell you exactly which to check.

I don't see a 5.3 listed for the 1999 Sierra, can you give me your vin?

Expert:  Mike S. replied 6 months ago.

No wait, I found it. Check these 2 fuses, the ECM1 and ECMB, both in the underhood fuse block.
