No Power to fuel pump

I have an 88 190E. Left it sitting for about a month, now it won't start. Check everything I could think of. What it comes down to, is I am getting no voltage to the fuel pump. Tested the pump and it tests out OK. Hoping someone can offer some insight...

THe power lines may have been disrupted in some way. Other possibility is the fuse blew.

Fuel pump relay probably.
