What is a CRK fuse?

[quickmotorsports]

This isn't necessarily a race related question, but I'm hoping someone out there may know the answer anyway.

I have a 1988 Chevy K1500 4x4 pickup and am trying to find out what the CRK fuse is as there is no power going to it. I appreciate any help on this.

Crank fuse. It'll only be hot when cranking and is used to inform the pcm that the engine is cranking, not running so it can alter fuel and timing for starting....
