Hello,
I have these codes on my 2000 3.8 and I don't know what to do. For the P0193 code I have replaced the fuel rail pressure sensor and have checked the wiring. It is getting 5 volts. I'm not sure what else it could be
hmm ill do some research and see if I can find anything until then try posting this in the tech section you should be able to get the attention of someone with more experience

Are you POSITIVE that the fuel rail pressure sensor intake vacuum reference line is connected, open, and leak free?
What have you done to rule out a problem with the FRPS signal return line back to the PCM? Have you checked the FRPS signal return line for shorts to ground or shorts to VPWR?
