I need a wiring diagrams for a 98 lincoln cotinetal. Diagrams of Fuel pump driver module, and wires going to fuel pump, and PCM.

Really appreciate it. Thanks

The FPDM is behind the back seat, passenger side, accessed from the trunk.

Low fuel pressure and code p0190, any Ideas?

You need a scan tool to prompt the FPDM to increase pressure so you can see if the pump FPDM and the pump responds. The code is for the fuel rail pressure sensor so that circuit would have to be troubleshooted. You would need the scan tool for that also.

Ok, I can troubleshoot the fuel pressure sensor, Can I get resistance specification. Thanks

No, you can test resistance. It is a 3 wire, 5v reference return sensor. You need to use a scan tool to see what the computer is seeing.

What type of scan tool? I have a obd2 reader, bought it a couple of years ago, it cost about 100 bucks. I have software and PC cable. Is a scanner and reader the same thing?

No, not at all. What you need costs more in the $8,000 range.

Ok, I tested resistance on FRP sensor. On sensor FRP to VRFE: 44.2k ohms, FRP to Sig Rtn: 44.2k ohms, and VREF to Sig Rtn: 1.4k ohms.

Also tested all 3 wires for opens between sensor and PCM and there was none.

Code p0190 is the only code that comes on, and wires going to FPRS are shared by lots of other sensors.

All that means nothing. Let me know if you get the necessary scan tool to resolve the issue.
