You do not have a relay for the fuel pump. You have a fuel pump control module which is why you are not able to find the relay.

I am attaching the wiring diagram below that will show the module.

I also attached below the process to replace it if this proves to be the issue.

Please let us know if you have other questions. Thanks

Sure, if you look at the diagrams above you can see that the fuel ump control module is under the truck and you will need to remove the steel cover to get at it. It is bolts to a cross brace towards the rear of the truck, you might need to remove the spare tire. Let us know if you need anything else.
