Truck will crank over as normal, no thrown codes but won't start?

Hello,

This sounds like a classic fuel pump failure, do you hear the pump run when you turn the key on without cranking the engine over? If not let's check the pump fuse and relay to confirm the pump failure. Here are guides to help you test the fuse and relay.
