So I have a 2006 F250 5.4l with 120,000 miles. About 2 months ago I was heading home to Illinois
from Fort Sill, OK and the truck died on the interstate. It would crank no problem and turn over for about 2 seconds then sputter out and die with no check engine light. Had 3/4 tank of fuel, inertia switch was still good, problem was a blown fuel pump fuse. Changed that and ran great for 2 months. The other day was driving on the highway and it died the same way and would sometimes turn over briefly and die but most of the time would just crank and crank however the fuse was still good and this time check engine light came on. Got it towed home put the reader on it and no found codes. I can hear the fuel pump prime and there is a new filter on it. Going to throw a pressure Guage on it see if I'm actually getting fuel but besides that I really don't know where to go from there. Any one experience this before?
Any advise would be greatly appreciated

 

Get the pressure reading, it's that important. You might need a scan tool, don't recall if that year still has a gauge port.

You might want to crawl under there and take a look at the fuel pump driver module. They have a nasty habit of corroding where they sit against the cross-member and cause all kinds of mischief.

 

Yeah I couldn't find a port on the rail. Would it be possible to get an accurate reading with an in line adaptor for the Guage say on the lnlet for the fuel filter? Probably be the easiest place to access the line. And scan tool? I have a code reader if I'm not mistaken what you mean?
Thank you for your response

 

Inline connector? Probably not.

Code reader? Nope.

Scan tool that can read live data? Yes.

 

Gotcha thanks again for the response. I'll figure out how to get a pressure reading and get back on here

 

Alright guys so still on the wild goose chase of figuring out the problem with this truck.
Changed out the fpdm because it corroded on the backside.
Check for power and ground at the pump. 12.14 volts and good ground.
Did a voltage drop test at pump everything looked good. So replaced the pump as wellong and still no start.
Fuses all good, inertia switch not tripped. Pulled the fuel line before the filter and primed the pump with koeo and absolutely no pressure coming out of open line.
In other words I'm frustrated wet cold and stumped on what to look at next.
If I am getting power at the pump could my inertia switch still be bad?
Talked to a ford mechanic and his exact words were "are u a certified ford mechanic?" My answer was obviously "no", he then told me then "you should always take the truck in when something goes wrong" well thanks for politely telling me I'm an idiot and not your not going to help even though I just shelled out over $500 in parts for your place of business.......Rant complete.
You guys have any advice of where I should look next?
Sorry for the long post

 

Also just checked the inertia switch and I have 12.10 volts

 

Sorry to hear that your problem was not resolved despite fuel pump replacement . What kind of fuel pump you used ? Motocraft or other brand ? rebuilt or brand new ?

If you take a direct line from battery to "fuel pump" , can you see the fuel at fuel filter fitting ?
Just a suggestion . Good luck.

 

I'll give that a shot next. Thanks for the post

 

Sounds like it's out of gas. That's what my Dad would say.
