Talk to me about no power to Main Fuel Pump - Need help 200 1988

I pulled the wires to the fuel pump, put the volt meter into the sockets, turned on the key and see zero voltage from the wires. So, I take the fuses out and jumped #4 and #6 and still nothing. (The other day I could hear a thunk by jumpering). Actually, I don't get much excitement today when putting the jumper on the left side of the terminals - just a faint little spark different than the other day anyway. The multi-meter I'm using has the pointed probes, but I moved them around enough with the key on that I would have made contact at some point and I verified the meter was good by reading DC voltage across the battery terminals first.

So, my question: What are the reason(s)that voltage would not be going to the wires for the pump? Is there any other fuse or something else I should be checking? Does the ECM (or ICM whatever its name) under the passenger side kick panel have any play in this?

I'm much more comfortable with mechanical than I am with electrical problems, in fact electrical problems want to make me run away as they just about short my brain out. R2
