Ford Focus Duratec HE/14 2.0L - P1000 and U1900 Codes: Engine Won't Start After Parking

Model: Ford Focus Duratec HE/14 Fault Code: P1000 Posted: 2015-07-30 05:27

My Ford Focus Duratec HE/14 with a 2.0L engine occasionally fails to start after being parked and switched off, but it will start again later without any intervention. Once started, the vehicle runs smoothly—no stalling or jerking issues. A diagnostic scan reveals only two fault codes: P1000 and U1900. I'm currently relying on luck to get it started, as it's becoming a gamble. Any insights into what these codes might indicate or how to resolve this issue would be greatly appreciated.
