Might be stuck injectors. You can find a Ford injector connector in your local auto parts store and use 12v fully charged battery, remove right side air-scoop, disconnect injectors plugs, stick the injector connector to injector, connect one wire of the connector to the battery, then shortly tap another wire to opposite battery contact. This trick can help you to unstuck the injectors. Anyway if injector works you should be able to hear clicking sound during connecting the battery. Do not connect injector to the battery for long time, just tap battery contact shortly.
