I Found One:
XS4Z9F972DA Ford Sensor - Fuel Injector Pressure
on ebay from
ford-parts-depot
It appears to be working but have only put 5 miles.
One thing that has happened which I don't think is related but began the first time I started the car after replacing is the following electrical do not work:
Radio
Key-less entry remote
Side mirror remote
Interior light
The sensor that prevents you from removing the ignition key unless in park
These are the things I have found so far.
