How can you tell your fuel pump is out

What is your question?

Sputtering when I have the ignition on and when I hit the gas pedal the car kinda jumps and then shuts off. Don’t know what it is but as most people have told me it’s the fuel pump but I need a definite answer. I can shut the engine off and turn it on and it will turn turn and turn but doesn’t start now if I keep the engine shit down for a minute and it starts I can hit the gas pedal and it jumps and just dies out. Can someone just help me to the answer so I can do it by myself. Just need an educated person to steer me to where I need to go. Thanks!

What makes this problem better or worse?

Well if I turn it on and it runs I hit the gas and it starts to jump and skip then dies out

How long has your 2006 Ford Mustang had this problem?
