Sounds like we have a pump issue, but we can't assume that just because we don't hear it that it is because you are not getting power.
Sometimes the motor will fail and will not come on at all when you turn the key.
So, the way to find out is to check the power at the pump or jump the relay after confirming you have 12 volts at the relay.
If you jump the relay and the pump comes on and the truck starts, then we may have a relay or control issue.

Let's try this and go from there. I am attaching the wiring diagram below for us to find out if we have power or not at the pump.
Let me know what questions you have.
Thanks
