No Power to Fuel Pump?

I have a '95 S-15, 2dr. Jimmy. It died while I was driving it. Found out it's the fuel pump. I check all fuses, relays, etc. i have pulled the tank & fuel pump. i checked the connection, on the frame, where pump hooks to for power. I turned the key on & no power comes through. Am I doing something wrong in checking this or what else should I look for?

Thanks for any answers....

Fuel Pump

Normally when you first turn on the key the start circuit will supply power to the fuel pump for only a few seconds trough a relay. In order to sustain power to the fuel pump you usually need to have oil pressure. At least a lot of vehicles work that way. It's a safety factor incase you roll the vehicvle.

Good luck, Bill
