2003 XKR check engine MIL
The check engine light activates after 2 trips. OBDII code reader indicates P1000 and P0193, fuel rail pressure sensor circuit high input. Engine runs smooth for short runs but starting to run rough, no messages appear. Is there a way to check the fuel pressure sensor?

I've moved your post to the XKR section.
P0193 fault finding
IP Sensor to ECM wiring (supply, sense): short
circuit to each other
IP Sensor to ECM sense circuit:
short circuit to high voltage
IP Sensor to splice sensor ground circuit:
open circuit
IP Sensor failure
(IP=injection pressure)
With your tale of woes I'd strongly suggest you go into the HOW-TO at the top of this section and download JTIS for your car.
It's a clunky great thing but is the ultimate service manual with instructions on how to do everything.
You'll find the owner's and vehicle care manuals in the same HOW-TO.
