'05 XLT cranks over but won't start

[darmahsd]

I just used the search function with the term: "fuel pump inertia switch" or "inertia switch".
I just don't understand how that comes up a blank.
In F150's, I think it's in the front passenger kick panel. Same on 2nd gen Expy?
Truck sat for two days. It's been kinda warm up here in NY. I'm second owner
of '05 with only 56K. Changed the fuel filter first thing after the problem
because maybe original owner never did. Didn't solve it.
I don't hear fuel pump running, either with my ear to filler cap,
under car or in engine compartment.
I even reconnected battery to boot ECU and tried another set of keys.
So tomorrow, going to check for fuel pressure and current to pump.
Heard that it could be inertia switch so that's why I'm asking.
If all else fails, will continue over to any spark issues.
Also, engine does not throw any codes.
I put 210K on my '97 Expy without it stranding me, so I'm a little bummed.

Thanks

On my 08 the inertia switch is all the in the back on the driver side. There's a little compartment for it. Your's might be in the same spot.

Its on the drivers side in the rear of the truck. There is a little storage area with a door on it, take the door off and you will see there is a hole and bingo!

I think the door is also labeled fuel cutoff.

I think it was a red button too

Bingo. That wasn't the problem, but found it. Thanks Guys

Duh, I also found it in the owner's manual later on.
I also heard that a fuel pump "module or modulator", located
by the left rear wheel and spare tire, is suspect and are always going bad.
I might yank and replace it. Anything on this?

'05 XLT Cranks over but won't start.

This fuel pump driver module is subject to corrosion and electrical failure due to where it is mounted on the spare tire cross-member, according to sources over at the F150 Forum. Corrosion because of exposure to road splash and the dissimilar metal to the frame rail that it is made of.
Ford wants upwards of $250 for this part, but at $58, the Dorman's
module I ordered from Amazon will be isolated from the frame member and is worth the expense even if not the solution to the problem rather than first attempting the more difficult task of fidgeting with all those quick change fuel lines and dropping the tank to replace the fuel pump. At that price I know I have a part less prone to failure and while swapping it out on Thursday, I can test electrical continuity to the pump. We'll see.

Removed the old Fuel Pump Driver Module. Knew right away that was the problem.
Kinda new to this forum, but I must respectively suggest this issue be made a Sticky. Better than that, hey Ford, HOW 'BOUT MAKING IT A SERVICE BULLETIN?
This thing looks like so many that I have seen researching the F150 Forum.
The F150's supposedly had more problems with corrosion being mounted directly to the frame.
On my '05 EXPY, it's mounted to a sheet metal bracket near the line of fire of the driver side rear wheel throwing road spray. Need to remove spare to make it easier to get to. First sign of trouble were the two 8MM bolts breaking off.
There's not even a suggestion of a fender liner or some kind of baffle to protect it. What's even more amazing is how much the force of the corrosion of the dissimilar pot metal pressing against this sheet metal bracket actually warped the snot out of said bracket. The hole that was formed meant water seeped through making contact with the PC board inside, and the oxidized powdered metal that also made it's way inside finally shorted the board out.
This module is the "brain" of your fuel pump, the thing that eliminates the return type pumps from modern injection systems. Ford could and should have taken a lot more care in where it mounted it and protecting it from the elements. I'm going to take further precautions, or, as my wife always tells me, overkill, to prevent this from ever stranding me. The Dorman's replacement that I got from Amazon- $58, at the recommendation of the F150 Forum, has two rubber isolators that keep it away from the sheet metal bracket and allow air circulation. This, and at a fraction of what it cost at Ford. I'm going to bed liner the metal part and make a flexible plastic "semi fender liner" to shield it from road spray.
I urge everyone who has this system in their Ford to check on it and replace/modify it so that it won't strand you like it did to me. And check it out before anyone fools you in going to more trouble and expense dropping the tank and replacing the fuel pump. Also, my experience shows that it doesn't always throw a code.
