Based on the pins you mentioned, you are working with the fuel pump balance relay. So, I assume the vehicle has dual tanks, correct?
I have attached the entire powertrain management wiring schematics for you. I highlighted everything related to the fuel pump.
Pin 30 should receive power from the ignition fuse E / balance module, so check both for power. I highlighted the fuse in the last pic below. The module is on the frame rail (driver's side). Note that the fuse should only get power when the key is in the start or run position.
When you check the fuse, make sure it is good and also, make sure power is present.
Also, here is a link you may find helpful when testing wiring.
Let me know what you find or if you have other questions.
See pics below.
