No power to fuel pump, 1980 280 ZX

I have kept my '80 280ZX stored at my mother's house and generally start and drive it every 3-4 months.  Sometimes I have to use a little starter fluid, but usually not.  Last week it would not start even with starter fluid (although it did start until the starter fluid was consumed). It appears that I am getting no power to the fuel pump.  By connecting the fuel pump directly to the battery I have confirmed that it is working.  In my manual I see 3 fuel pump relays, two under the hood and one inside, but I see no fuses listed, which I assumed was the problem.  Is there a  way for me to test these relays, and is there a fuse some where?
