With a V10, you can replace the fuel filter as part of your problem elimination process. It's inside the driver side frame rail, under the cab. You need a filter, part number shared with some of the Ranger trucks, and a 5/16" disconnect tool. Here's a thread about it. 
There's a Fuel Pressure Test Fitting in the engine compartment. Near the transmission dipstick, Green Cap on it. If you change the filter and it doesn't have pressure there, two prime causes are:
1. Failed Pressure Regulator
2. Failed In-Tank High Pressure Fuel Pump
I hear of far more Pumps replaced than Regulators.
