fuel pump? on 2001 Ford Expedition

How can I tell if my fuel pump is going out? In the last couple of weeks my car acts like it doesn't want to crank. It turns over without losing power, but I have to turn the ignition off and try again for a few seconds before it cranks.
Could it be the fuel pump or something else?

You will need to have a fuel pressure gauge on the car when the car wont start to know if the fuel pump is the problem. If you don't have pressure, then verify the pump is getting power when it isn't working.
