Whistling noise under slight acceleration
check for a cracked manifold or cracked flex section at the manifold
it is under load so it is not a vacuum leak as the vacuum is low under acceleration and high under deceleration or idle
indicates a gas leak or possible blockage from failed cat converter

I have a 2006 ford f350 and the fuel pump isnt
Yes. The switch is usually located around the passengers kickpanel. There should be an access hole to press the button on the switch. Sometimes the part is just above the carpet and sometimes you have to remove the kickpanel. If you are unable to find this switch on the passengers side,then look on the drivers side kickpanel.
Under the hood is a Powerbox. The shutoff switch (inertia switch) gets its power from the Fuel pump Relay after the Ignition is turned on. If resetting the shutoff switch does not help, your fuel pump Relay may be bad. On some Ford models, the horn Relay is the same Relay used for the fuel pump. This would allow you to swap and test before buying a new Relay.
