Answer
Hello Jay,
Rollover valve is just a ball in the line system that keeps fuel from draining out if the truck is lying on its top. Nothing to reset.
I immagine your fuel pump isn't working. First check the fuse.
Listen for the pump to run in the tank. It is supposed to come on and run for three seconds when the key is turned to run. You should be able to hear it.
