Ford F150 Fuel Pump Problems Repair Solution 

despite negative comments, my guess is they probably have never worked on or even troubleshooted a vehicle in their entire life. good video and i had the same problem on my truck, a good mechanic finds the problem and fixes it, no matter how long it takes. good video thanks.....

what exactly was your symptoms? would it run for days and then die, and just crank and then after 20 minutes start?

We had taken this truck to several shops and dealer. I was a truck we were going to sell. Due the problems we did not sell and still own it.

have a question I have a 2005 f150 5.4 and my problem is that my my fuel lines don't stay pressure up when I try to turn on truck. so it stalls and I have to try it like 3 times n turns on. they have checked it and there's pressure once on but when I turn it off slowly starts losing pressure what could it be. have changed fuel pump, rail sensor and the one by tank. need help

wow someone threw alot of parts at that truck...smh and not cheep ones eather.. very expensive guess work...but oh well it works now.. we all been there before, lesson learned.

i LOVE THE SARCASM !!!!!!!!!!!!!!!!! You never miss a chance to make a sell, no matter how big or small!!

Steve good job! Great documentation. Pay no attention to the negative comments.

Spent a thousand dollars to not correct a 50¢ issue, parts can’t function without being properly connected, thats why competent techs do whats called “Troubleshooting” I know about three competent techs. Maybe four.the rest are parts installers, keep on installing until it works, why bother to understand the integral functions of system when you can blow tons of money and still stare at an immobile automobile!? Rule #1 thumb, Ford electronic components fail due to wiring, most commonly a lost or faulty ground , secondly a rub through causing a short to ground, thirdly, a failed continuity at the connectors or component terminals

Good job,congratualtions on sticking with it from start to finnish.

My 2009 f150 did the same thing. i just had a burned relay. If you have the same problem its under the hood #27 i think 20A

I definatley will buy a car from these guys not even the dealer would of done all of that work!

Too easy to criticize these guys for making a mistake---it takes a lot of balls to admit it so publicly---kudos for that! I'd also bet most all these snarky comments come from those who've done this exact same thing, at least those of us who aren't full-time or professional mechanics.

Thanks, Steve, I also was on my way to put all the part as you did, Found your youtube and saved a bunch of MONEY. Had same problem. Joe of Hongkongwillie

one shitty mechanic. just throw parts at it.

You might could have just used some deoxit to clean the connector contacts.

I got the same truck even same color! haven't driven it since the day I bought it. Got it home and it wouldn't run again. I changed out the fuel driver module, fuel filter, and fuel pressure sensor. was getting ready to go after the fuel pump and I realized the bolts on the bed was not all the way in and two of the bolts were not factory. I'm pretty sure the previous owner already replaced the fuel pump. I'm going to try to check out the wiring now.

I have a 2005 f250 if I manually power the pump it runs , I changed the FPDM because it looked awful truck still won't start .. I did check the reset switch it was fine .. Now if I hook up my scanner and go to functions , I go to command fuel pump duty cycle I can't change the speed 10 % at a time.. It will only allow me to doing the pump at 40% then I try 50% and the pump shuts down and starts bumping and jerking , until I command it back to 40% . Oh and when I do this and it spins at 40% the truck will fire up for about 4 seconds ..

Can anyone please tell me were is the fuel pump control module located on a 2007 ford Expedition SUB It is not under wheel well were the ford F-150 pick up is I have change the fuel pump in the gas tank and the truck still run and shut off from no fuel

I spent lot of time trying to resolve a power loss problem. The great discovery was that my old 80s vintage F250 had both a low pressure fuel pump inside the tanks, but also an external high pressure fuel pump which only activates for little tasks like maintaining highway speed or climbing hills. That high pressure pump was dead as a door nail.

Jeff Cotton hit the bulls eye.

My truck is exactly like yours but on mine it won't start like I turn the key and it sounds like its going to turn on but it doesn't I think its a bad wire

At least they kept trying to fix it instead of just selling it..i would bye from them in a min

electrical f-ing nightmares

By Chance were You Blowing the #9 Fuel Pump Fuse ??

Did u had power on one of the wires before replacing the switch?

What where the symtoms for this truck? I have also replaced fuel pump, pressure sensor, and control moduel. My truck looses fuel pressure when in drive or reverse and starts too stall

hahahahaahaa,,,good luck and have fun,,,,I,m in Valdosta....

Thank you so much you saved my ass with this video

Sounds like my F150. Change the PCM, sensor, and FPDM. New FPDM was defective. Change plugs and replaced bad coils. Pulled fuel line before filter and fuel came out when cranked. Hooked everything back up. Still not running. I think it maybe air locked. So I will try pulling the sensor out to let air out when cranking the motor. The fuel system is a returnless system, so I am thinking it may need to be bled like a diesel to prime the fuel system.

Thanks for the Heads up on this issue , I replaced the fuel pump driver module , 2 days ago & had the same issue ? I jumped that box plug this morning & so far my work truck is running normal again . Easy fix ... Thanks again .

Holy crap , you guys need a good mechanic . If you had followed the flow sheet verbatim you would have found high resistance in that wire . Also never use scotchlocks , they are for installing radios . Solder in butt connectors and shrink tube it, obviously you guys don't know how to change terminals. Your repair will corrode in a week . 3000 dollars for a bad connection , stick with seat repair .

was the truck running then shutting off? Mine runs then shuts off and wont start again till it sits.

my truck runs good on back tank but runs bad on front tank and has started bleeding gas back in front tank any help?

awesome info thanks for sharing

Thanks for the video!

Exactly why I don’t take my vehicles to a place like this. You’ll pay for every part that wasn’t needed. And it was a ground issue.

FORD DID US A GREAT favor 🤣🤣🤣🤣🤣🤣🤣🤣

i got a 92 f150 single tank .i the pump whent bad cause of rust in the tank so i got a plastic tank and a new pump ,but i go to plug it in and the trucks plug is geting 8 volts and 6volts constent ,no 3 second burst ,pulled the relay ,still getting constent power ,,help?

Good job on the video. You could make it easier for new customers to contact you. By adding your phone number to the very beginning of the video description. That way anyone who needs help in your marketing area who finds your video on their cell phone. Only has to touch your phone number that is visible just under the video to contact you and ask for help. Great job on your video.

You should price things as you go along... you did a lot most people can't afford to waste $$ AS stated before the flow chart could save time and money.

THANK YOU...

How did you know it was that wire?

good job. You guys are persistent.

Hello Steve, Did the fuel pump problem cause an idle problem?

You guys need a real mechanic. Jeff Cotton said it best.

google this pop/up universal fuse

would this work for a 93 as well?

Wow

All y'all are just parts changers do not know how to find the problem u just slap on parts and waste money

will try this first thing on the morning! i wish my truck looks like this underneath!

inerta switch beside the fuse box .its a reset press on the top (red push button) your problem would be solve

dang, you took the bed off... man o man, no offense but the mechanic I use would have rapped this up in a jiffy......

sounds like you did it the hard way. Did you try Fuel Pump reset switch? Seen other people rewiring because they didn't know this switch exists. easyautodiagnostics.com/ford/4.9L-5.0L-5.8L/fuel-pump-relay-tests-2
