Fuel Pressure Sensor 1999 Mystique

I have diagnosed my issue to the Fuel Rail Pressure Sensor. It appears the diaphragm is blown. I can get the car to run fine by plugging the vacuum hose nipple and disconnecting the wiring but now the check engine light is on. I have tried Ford and every other parts house I can think of and I am unable to find a replacement Fuel Pressure Sensor. Ford says its a discontinued part.

Anybody have a source for a Fuel Pressure Sensor or a work around for the check engine light?

Thanks

http://www.rockauto.com/ It shows a fuel pressure regulator with vacuum. It also shows a fuel pressure regulator for the gas tank. Both parts are Standard which have worked for me.

rhandwor,
I am NOT talking about the Fuel Pressure Regulator or the Fuel Tank Pressure Sensor.
What I need is the Fuel Rail Pressure Sensor (Fuel Injector Pressure Sensor). Its a small plastic part at the beginning of the fuel rail and can been seen below the air cleaner. Its has a port for incoming fuel, outgoing fuel, and a vacuum hose nipple. It also has an electrical connector with 3 contacts. In the original post I included a picture.
Here are part numbers I have come across, though some sites show the correct part, while others show the Regulator
Part Number per Ford Dealer: XS2Z9F472FA
AIRTEX / WELLS 5G1143
WELLS SU13803 / AIRTEX 5S12388 / CARQUEST 722809
Alternate/OEM Part Number(s): PR240, XS2F9F972FA, XS2Z9F472FA, XS2Z9F972BA, XS2Z9F972FA

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.

With a meter, I have have physically check all the fuses in the Power Distribution Box (under hood) and Passenger Compartment Fuse Panel.


Fuses 29, 31, 33, & 35 have no power on the (+) side of the fuse block (lower bank of passenger compartment fuse panel.


Any Idea? I have looked over previous posts and have found issues with a wiring recall but that appears to be associated with earlier models.

Try checking for power with the light switch on.

The pictures show big fuse able links in the power dist. box.
The other one is older style used by starter.
With negative disconnected turn box upside down and look for corroded wires or connections.
