if it is a electric fuel pump take the fuel line off carburator and get a three foot gas line hook it up to the gas line on the car run gas line into an empty gallon container and turn key on and see if you are getting a good flow of gas

Check your fusible links; these are small wires molded into the middle of a bigger wire they are usually located up by the battery cables. When they burn they become discolored and softly flexible. Also check your relays too.

possible just not probable. you need to see if there is any pressure to fuel rail. if not youre going to have to by pass the fuel pump and see if it is getting voltage. if so then apply a seperate voltage and ground wire to the pump to see if it kicks on. come to think of it, it could be the PATS system(security) that shuts down the system. it will crank but will not fire. your ford dealer will need to reprogram the system.
