Ford Repair Questions? Ask a Mechanic for Answers ASAP
Hello! My name is Gary.Welcome to JustAnswer.I'm reviewing your question now, and will post back with a reply shortly.
If the dealer says fuel pressure, they should be looking at the whole system, including the rail pressure sensor data.
The Ford data tool can log this on a road test.
The tech should be able to tell under what conditions the code set.
Could be immobilzer related, but should log a code in one or more modules.
Could be a low pressure fuel pump relay, poor contact in the fusebox etc.
Difficult while it is intermittent, it will become easier once the fault is repeatable.
Not on your model so far, but others are similar.
Being now 3 years old, I would look at the battery cranking voltage, and whether the immobilizer is reading the key correctly.
It could also have the start of a low pressure fuel pump failing.
I do hope it is not a high pressure pump issue.
Do you need any further help?
I hope my advice has been of assistance to you.
Your dealer should keep your car overnight for more testing.
Cold starts, warm restarts etc, different scenarios.
