Do you know how much pressure there is? If I recall correctly it's to be somewhere around the 60 PSI mark.
Also, was it a motorcraft or aftermarket pump? Aftermarket pumps can be dead or be faulty straight from the start. Motorcraft pumps are pretty much unheard of in this respect.
Any leaks? Fuel smell? How long as it been since the fuel filter has been replaced?
If none of these check out, purchase some starting fluid and spray it into the throttle body as the engine is cranking. If it starts with the starting fluid then fuel is our problem. If it doesn't start, then you've lost spark. AKA, a 50/50 test. As you know, the engine requires both fuel and spark to do what it does. If we can eliminate one of them, that will make the job a lot easier.
