1989 Toyota Pickup No fuel pumped up to the engine fuel pip

Hi guys! I was wondering if you may know why I'm not getting fuel up to my engine. It's my moms motor home with a toyota v-6 engine. It's got plenty of gas in it, I confirmed it's getting spark to the plugs, and disconected the fuel line up at the engine and got no fuel. I turned the ignition key on all the way, then took my 12volt power light tester and checked the plug wire that hooks up to the "in-tank" fuel pump. It did NOT light the light of my tester so I think I may not be getting power to my fuel pump. I've checked all the fueses but they all look good.
Do you have any suggestions? Would an engine code tester help determine the problem? What do you suggest? Thanks guys! Brook
