Hello Dennis.
When you are checking fuel pump voltage on your pickup when you turn on the key the voltage is only applied to the pump for a couple of seconds unless you go to cranking position.
There are 4 wires leading to the fuel pump on your truck. The gray wire is the 12 volt positive power feed to the fuel pump and the black provides the ground. The orange and purple wires are your fuel gauge wires.
The relay for the fuel pump is in your under hood fuse panel and I believe is marked on the underside of the fuse panel cover. It should click on and off again quickly when you turn the key to "on". Having a helper to cycle the key would be handy while you put your finger on the relay and listen to it. Just because it clicks still doesn't mean it's functional but relay failure on these models is somewhat rare.
I would start by checking for power at the fuel pump harness.
Fuel pump issues are quite common on these model year trucks.
Hope this helps you out.
