Fuel pressure sensor / Fuel Injection Sensor / Fuel Rail Sensor

1999 Mercury Mystique 2.5
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.

[FONT=&quot]According to Ford, the part is NO LONGER AVAILABLE and I have had no luck finding a replacement. Everyone is trying to sell me the fuel tank sensor or the fuel pressure regulator. Apparently they had 3 different fuel systems. A return system and 2 non-return systems, one mechanical and one electronic. I have the electronic system with a blown diaphragm.[/FONT]

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

are you looking for used? I would look at u-pull Junkyards. Check if other fords use it also. Example the Taurus and fusion that also use the duratech.

Is your '99 an early or late model 99? Check the month and year on the door sticker.

having a fpr that has an electrical connector means its a late 99 with a returnless fuel system. Suggest searching for the part using MY 2000 instead of 99, might help.

I got curious enough to go look at my recently acquired 2000 SE 2.5L. It has the same style sensor as the OP's but the vacuum line is capped off at the sensor.

I did some poking around and also came up empty handed for a replacement sensor for the 99-2000 Contour and the Cougar (up to 2002).

I wonder if a Standard FPS6 for the '00 Taurus Duratec would work. Looks the same as the photos in post #1. http://www.rockauto.com/catalog/moreinfo.php?pk=3790131

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.

Okay, that part number crosses to a Standard FPS4, Wells SU13803/6 or an Airtex 5S12391, all of which are readily available. Strange than none of the cross references found the parts by application, but when looking to see the applicable vehicles that they fit, the 2000 Contour is listed (as well as others).

The electrical problem is likely a blown fuse. Check fuse F34 under the dash. It's common to everything you listed.
