Whining fuel pump when KEY ON
So I ran the truck out of fuel a few thousand miles ago and noticed that when I did that the fuel pump in the engine compartment was whining real bad. I filled it up and after a few minutes the whining went away.
Now every time I turn the key to the on position without cranking the pump whines for a 20 - 30 seconds until it fully primes itself.
Shouldnt the fuel system be staying primed? Anyone else notice this?
