What are the signs and symptoms of a fuel pump needing replaced. Other than the obvious that the car will not start 2000 Nissan frontier V6, 3.3L 4x4 crew cab

You don't hear it running when your turn the key on just before the crank position.

You have replaced the fuel filter and it was pretty much stopped up. (destroyed pump trying to pump through stopped up filter.)

Because it was going bad you couldn't drive fast because it wasn't pumping enough fuel.

Disconnect fuel line and see if fuel comes out when you turn the key on.

My car need a new fuel pump. Its a nissan v6 3.3l hardbody double cab
