 Auto electrics have never been my strong point.

John,
May be the problem,
Disconnect the plug , key position 2,you must have 5 volts on the middle pin
(Purple/black) ;it come from the ECU.
The sensor send back a variable voltage from 0 to 5 volts on blue/yellow wire
representing the pressure.
I forgot,you can try this: (costs nothing)
Simply,get up the camsensor of 1 or two millimeter.

You can also clean the rail pressure sensor contacts
