2009 Expedition EL - Crank No start. Fuel pump?

[FatTees8314]

Problem started two weeks ago, when I stalled on the side of the freeway.

Crank no start. Thinking I was just overheated, I let it cool down, problem persisted. I get it towed home.

The persistent problems leading up
• rough idle when hot
• irregular power (more erattic at higher temp)
• can be sluggish up hills
• irregular sluggish throttle response

Never overheated according to gauge

Everything is telling me its the fuel pump. I bute the bullet, get the fuel pump swapped out. Everything hooked back up. Truck fired right up. Horrendous idle. Drove around block, stalled out. Restarted. Drove home. Let it continue to idle (idle and throttle response was improving), so I assumed it was learning.

It stalls out. Now it is back to a crank no start.

I am absolutely baffled as to this chain of events.

Have you put a code reader on it and see if it throwing any codes?

Other than that, back to the basics, do you have fuel pressure, spark, is the throttle body opening

I had an 2009 F150 with 5.4. Had same issue.
Ford had a TSB and a kit to relocate the fuel pump fuse to an unused location in the main power distribution fuse/relay box on top of the radiator.

I have an 2009 Expedition and have been almost totally disable if the weather gets above 30 degrees. It seems to me like the codes are always pointing to the the issue the engine has when it gets hot and can't cool down. I read that if the engine oil and the coolant get within 10-15 degrees of each other that the whole system geeks out and shuts down. The oil heats up and gets too thin. Then can't get up and stay in the engine. Then everything starts falling like dominos. I think the key is the oil cooler.

FosterMD,
I’ve never heard of that, but wouldn’t that condition prevent the vehicle from starting at any temp if the vehicle sat at ambient temperature for more 6 hours? If is 24 degrees outside Ike today or 105 in the summer. Oil and coolant will be at the same temp or in the 10 to 15 degrees for at least 10 or 15 minutes?
A thermostat stuck closed could create or extend such a scenario give the right ambient conditions. I’ve seen over heating for a number of reasons but never heard of the computer shutting the engine down.

In 70s and 80s vehicles Ford had an ignition box when failing would get extremely hot and prevent proper firing… bag of ice on top of the module would get you moving and usually back home.

My best guesses from here are a vacuum leak, check all the vacuum lines. Or the fuel pressure sensor, an internal leak in the diaphragm will cause the PCM to improperly control fuel pump and injector timing.

Update:

Crank/No Start continues

Can hear the fuel pump engage
The shrader on the rail shows fuel is being sent

tried SureStart... nothing

Bit the bullet again, and resolved the only code being shown... and swapped the VVT solenoids (P0012, P0022)

With the lack of sure start doing anything, I also replaced the throttle body and ignition coils (mobile mech refused to swap out the spark plugs, after repeated prompts to do so) so I'm doing that in the next couple of days myself....

Still no start... but is cranking strong and long.
