CEL P0190 - Fuel Rail Pressure Sensor Malfunction

The zero cost way to rule in/out the fuel pressure sensor is to monitor the fuel pressure with an ODB2 scanner. The pressure should be around 40 PSI (+/- 3-5).

Double the fuses before getting in too deep. Especially F2.2 and F2.8.

Assuming that the theft light isn't blinking during cranking. Have you tried unlocking the driver's door with the key? Or used the remote key FOB to lock/unlock the door?

If I say, "yes the SCT can monitor ODB2 operational PIDS", is your next question going to be how?

I was under the impression that all tuners (except the budget flash only tuners) can data log ODB2 PIDS. Each tuner has their own procedure. Have you looked at the manual?

Are you sure it's not FPDC (Fuel pump duty cycle)? In any case, not likely the PID needed.

Do you have a full list of SCT PID's to review?

Do you hear the fuel pump run at initial key on? Have you confirmed +12 volts at the trunk mounted IFS switch with the key on? If no voltage the problem is in the CCRM or ignition switch.

Have you double checked the fuel pressure sensor electrical connector? Is it clean and tight? Post the voltage between the BN/WH and GY/RD wire. Should be about 5 volts with the key on.

Post the voltage between the RD/PK and GY/RD wire with the key on. This should be the fuel pressure signal return. The Ford service manual says the KOEO value should be about 3.7 volts.

While you are at it, data log RPM's. This will confirm a good CKP sensor which is a "no start" sensor.
