no fuel driving me insane
So I pulled out of the driveway and the engine died. Cycled the key and no fuel pump. Today I pulled the bed off checked for power at the fuel pump connector. While connected it has no voltage, unplug it and it has 12 volts. Checked voltage at the relay 12 volts unplugged, 0 volts connected at the orange and lt-blue wires. Did the same at the computer. Tried running a jumper wire from the relay back to the pump connecter, and nothing changed.

Here's the wiring diagram. any help would be appreciated.

yes it was the only thing unplugged, but I have another pump out of a previous truck and it does the same thing. it worked when i took it out, but it's been sitting for the past 3 years in my barn. Also, I can wire it directly to the battery and the pump will run. like I said, it's driving me insane.
Edit: the second pump did have 0.25V, but thats still nothing really.

If you have an Ohm Meter try checking the resistance between the ORG-LT BLU wire with the relay unplugged and the PINK-BLK wire connector at the tank. Or you could try applying a jumper between the battery positive terminal and the ORG-LT BLU wire at the relay output and see if the pump will run. If it still doesn't run try jumping between the battery and the PINK-BLK wire under cab connector.
