Hi all…quick update. Put a fuel pressure gauge on the fuel rail. No real pressure with key on “run” position, where I would expect the fuel system to pressurize. While cranking, the pressure slowly builds up to about 30 psi and it then starts. I’m guessing that the fuel pressure sensor is telling the PCM not to fire the injectors or in some other way prevent the starting until appropriate pressure is reached.
Once running, the pressure builds to about 45 psi (not sure if that is low or within acceptable range). After shutdown, I monitored the pressure for 40 minutes. Dropped from 45 to 40 psi over that time, which I thought was reasonable.
Therefore, I am lead to think it is either the fuel pump or the fuel pressure regulator. The owner says the pump was replaced about 10 years ago, but can still be suspect.
Question: on a 2007 Navigator with 5.4L 3 valve…what kind of fuel pressure regulator is used? External? Is it one like in the picture?
Thanks!
Bob
BTW, this isn't true, and what is happening is limited to the US.
I can foresee Chinese brands getting a foothold in Canada soon, which will put more pressure on US Makers in the EV space, and may force further retrenchment from EV Sector.
Here's one

If it is worse after you refuel, you might have a bad vapor canister purge valve. If it is stuck open it will "flood" the engine and cause a hard start. Usually you will have related codes to the purge valve though. You can take it out and try blowing through it, if you can blow through it, it is stuck open and replace it. If you can't it is either working or stuck closed, but if it is stuck closed you shouldn't have the hard start condition.
ok, let’s look at business case issues,
Even if Ford could launch T3 tomorrow with all of CE1’s manufacturing improvements,
there’s still the the problem of the mandatory big battery, it’s higher cost and the
affect the added weight has on the expected range when either carrying or towing loads. There’s no getting around the difference in cost and capability between the
ice F150/Expedition and the T3 pickup and Utility.
All of those issues are interlinked and exactly why there’s still not enough buyers,
Ford is hoping that changes in three years time, Ford has already taken three
years to watch Lightning perform in the market so they know the temperature
of today’s market and what’s coming next year….
It's possible, the issue is this sort of look has been used to describe t3 as well. So IDK if this patent hints more at the general shape of t3, or CE1. Maybe they'll both look like this, who knows.
Not sure about the feature this article is highlighting, BUT, the front end design with a fold down "front gate" (front tailgate) and hood may hint at the CE1 truck look?
