Veh. Cranks No Start, Do you know what this circuit is?

This post is actually an orphan based whereby I will paste the original at bottom.

What my query is for identification of circuit #1 (L to R) of a 5 circuit fuse block with a cover marked "MOTOR-SICHERUNGEN" located inside the computer control box. Perhaps if anyone has a resource for what is specifically 1999 E-36/7 (Z3) circuitry mapping (schematic). This circuit shows no voltage in all key positions, and is the reason it is suspect among the critical circuits on this fuse block.
Is anyone aware of what this circuit's function is? I would like to know this circuit's path from source to load. I greatly appreciate anyone who can shed light on this circuit for me.
Here is the original thread which has gotten zero response
Not a battery issue, plenty of power to spare. Almost all fuses / circuits check out, power is coming and going from them respectively, except for one.

This fuse is inside the computer control box (RH firewall) in position #1 (from left to right) of the 5 fuse block marked "MOTOR-SICHERUNGEN" (motor fuses) I cannot say this fuse is bad, but can say there no power coming or leaving this circuit @ that particular location. I have pondered and checked for shorts.

I am not certain but have reason to believe, as it appears to be possibly coming from the computer, but I could be in error. Does anyone know what this circuit is and why it is dead while all connections to and from it appear to be ok. My alldatapro computer crashed during a backup (imagine that) so I cannot look it up. The circuit being dead in all positions including start gives me reason to believe it could possibly be why the veh. cranks but does not start.

Anyone that can shed some light would be greatly appreciated. Once again, this fuse is not blown, but there is no power coming or going from this circuit in all key positions.
