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
