One way is to drain the fuel bowl, take the filter lid off to make sure it's empty. If it is, put the lid back on and then turn the key to 'Run' not start. If the the pump is running right it should fill the bowl back up. You'll have to take the lid back off.
OBS's do not have an electric fuel system like the Super Duty's do. Our fuel pump is mechanical and runs off a cam in the motor, so turning the key to run does absolutely nothing for us.
Usually the fuel pump starts leaking before it goes bad. Usually when the truck just dies, it is when the CPS goes bad. To check, watch the tach when you crank, if it doesn't move, then the CPS is bad.
