Sounds like maybe fuel pump. Pump and strainer are in the gas tank. They are a ceiled unit. Would recommend replacing if you are having trouble. Check for a service hole before removing the entire tank first. Can save a lot of time.

I have a 2005 f150 5.4 3v...Accelerates and goes through the gear just fine as long as you don't press the accerator all the way down. It seems the as long as you keep the pedal about one inch from the floor board its normal but once you pass that inch, it will bog down at any rpm...Any ideas...Already changed the mass air throttle, fuel pump, injectors, fuel filter, Oxigen sensors...Thanks for any input...there is no codes.

Pappybeare from United States 3 years ago
I have read that a front windshield leak causes the GEM module to short out if at any time you have things that come on and off without you turning them on. It is a box connected directly on top of the under dash fuse box. It is very hard to get out, and they are hard to find for the older trucks. You either have to buy used or remanufactured, and the model number of your part has to exactly match or all of your options will not work. I’m still trying to get one for mine, but haven’t had any luck. I have looked for a cross reference part #, but haven’t had any luck. Even my call to Ford ended with them telling me to find an electronics repair shop that can refurbish mine. I still haven’t found one that will guarantee the part for more than 30 days, and they want me to send my part to them and then wait for them to make the repair and they will mail it back. The cost is astronomical too! To have mine repaired it was $400, and if I want to take a chance on a junkyard part, I can get one for $150. The junkyard part is only guaranteed with an exchange if the part they send don’t work. I can’t find any information on specs, or any testing methods. I’ve even tried to get nomenclature to find out what the model #digits mean. There is mot much good info on this part. I hope this helps. Make sure you have the windshield resealed before replacing the part if that’s what yours turns out to be.

So driving down the road and the solution came to me, in the form of my under dash fuse panel. It caught fire! Got it out with minimal damage. New fuse panel (and a couple short wire repairs), no more issues! Not my preferred way of finding the issue but it is solved and fixed.

Anyone have any updates on a repair that will fix this??
JaRe from Canada a year ago
I took my truck into Ford Dealership. Of course, everything was working fine that day. Told me they couldn't duplicate the problem in the shop or on a test drive. They decided to perform a self-test on all the modules and found multiple modules lost communication with the BCM (Body Control Module). Ran a self-test and network test on the BCM and it passed. Performed an inspection of the BCM itself and found C2280B on the bottom of the BCM to not be fully seated and locked. While wiggling this connector they were able to duplicate the no radio, heat, defrost or center console controls. Reinstalled the connector and made sure it was fully seated and locked. 3 days later and I haven't had any issues since. Cost me $190 labour but I wouldn't have been able to figure this out myself.

In the 2004 ford f150 if you have that problem its the ground screw on the passenger side because they left out sealent around the windshield,water gets down in the passenger side. Take off the panel by the fuse box towards the door and check the ground,its usally russted away. Take and put in a new ground screw or use one already there.

Bruce from United States a year ago
There are a few possible causes for this issue, but here are the most common ones:

Blown Fuse: Check the fuse panel in the engine compartment and inside the vehicle to see if the radio fuse has blown. If it has, replace it with one of the same amperage.
Wiring Issues: Check the wiring to the radio and the speaker system. Make sure there are no cuts, frays, or corrosion on the wiring.
Radio Unit Failure: If the wiring and fuse are both fine, the issue may be with the radio unit itself. This could be caused by a malfunctioning amplifier, a problem with the wiring, or an issue with the unit's firmware.
Speaker Failure: If you have sound from the CD player but not from the radio, it's possible that the speakers are at fault. Check the speaker connections to make sure they are secure and the wiring is not damaged. If the speaker cones are damaged or blown, you may need to replace the speakers.
It's always best to consult with a professional technician who can diagnose and repair your car's audio system. They will be able to properly diagnose the issue and repair it so that your car's audio system functions properly.

I believe that I found the answer, though I haven't had time to test my theory. The long and short of it is that the truck is telling me that I have a warning light out on the dashboard. I'm too tired to remember what one, but I do have one out, and I hope to replace it this weekend.

Acuator clicking quick fix to stop -fuse? SolvedSolved

Ford F-150 2011 F150 150000 miles
My actuator is broken and his clicking. I have a 3 Hour Dr. ahead of me hoping I can remove a fuse to stop it. It is a Sunday and I cannot get to a mechanic. I am three hours from home.
Troy from United States a year ago

1 report 
Bruce from United States a year ago
If you're hearing a clicking sound from the actuator, it may be that it's stuck in an open or closed position. The clicking sound is likely the relay inside the actuator cycling rapidly, trying to activate the actuator. In this case, removing a fuse may not solve the issue, as the relay will still cycle.
If you need a quick fix to stop the clicking sound, you could try disconnecting the battery for a few minutes, which will reset the electrical system and potentially stop the clicking. Just be aware that disconnecting the battery will erase any saved radio stations and may reset the clock, so you'll need to reset those once the battery is reconnected.
If you're not comfortable with disconnecting the battery, it would be best to try to get the vehicle to a mechanic as soon as possible so they can diagnose and repair the issue.

I will just let you know right now because I had a similar problem. It might not be the fuse for either the cigarette lighter or the 112 V power it could be the actual cigarette lighter socket itself. I got one at AutoZone for like 10 bucks and that’s where the problem is because I replaced the fuses and that wasn’t it, and mine came out really easy with a flat head screwdriver and a twist and then you just disconnect the cable and connect the new one

I ended up getting my truck towed to the dealership, a broken wire in the harness going to the fuel pump relay switch which is located above the fuel tank on the cross member, when the sensor is not working it will not spark , they found the break in the wire and replaced the sensor, cause the location is a common problem, it's not protected very good and basically rots. Hopefully this helps :)

I had the same problem with the overdrive warning light, it could be two things: an electrical failure or a mechanical one inside the trasmission (either the gear cogs or the solenoids), let's hope it is electrical as it is easier to repair. What I did to fix it and you should do is get your user manual, download it if you don't have it, and then check the fuse box on the side of the engine: there is one that is of the transmission sensor, with the help of the manual you can identify it. If it's blown, you only have to change it. Then just pay attention and check it periodically, if it blows again it could be that is overheating either because the oil level is low, or that the oil is too dirty and the filter clogged, in the latter case doing an oil and filter service is what you need. This worked perfectly for me, hope it helps.

Possibly have air trapped in the cooling system. Google that model of engine and see if there is a bleeder for air around the thermostst housing?

If water passes through too fast without a thermostat at all an engine can overheat as well. Passes thru the system too quickly!

Hazards/turn signals not working

Ford F-150 1998 F150 190000 miles
I can't get my hazards or turn signals to work. I've replaced the flasher relay under the dash and the 20 amp fuse is still good. All the blind are good. Still doesn't work. So now I'm looking at the turn signal/flasher switch on the steering column. Has anyone ever heard of one going bad? It's over 90$, so I wanna be sure. I've haven't blown a fuse yet for this.

Yes, indeed, I've heard (and read) of many people that had this problem and it got fixed after changing the flasher module. You should be able to get one for less than 20 bucks. I hope it fixes your problem as well! Let me know if it does, so that I can count one more on the list ;)

I’ve replace relay , checked fuse, still no turn signals. They work time to time. Any suggestions
2wrench from United States 4 years ago
I had a weird situation where the right turn signal to a trailer hooked to my 2003 F150 would not work. I found it was a bad small fuse in the plastic fuse cabinet under the hood. That cabinet is a bear to open, but it swings up pulling from the fire wall side of the truck. Feel to the left rear corner as you look at it. A mirror was helpful to see what I had to pull. Inside at the top was a fuse creamish/clearish in color with the number 2 on it. Replaced it. Right turn signal works. Go figure, but that was the problem. I would note my left turn signal on the trailer worked fine.

Ran out of gas, Carberated, won't start now

Ford F-150 1989 Pickup 156 miles
My son has a 1989 ford f150. He ran out of gas, put gas in it, sprayed started fluid, changed the fuel filter, checked the air filter, and reconnected the battery. It tries to start, but won't catch. We don't really know much else to do, any suggestions for a newbee diy'er? :)

Knuth from United States 8 years ago
First, make sure you have enough gas in the tank. Then, turn the key for 2 seconds, and let it rest for a couple of seconds. Do this again a few times: the goal is to fill the gas system. Pay attention to see if you can notice whether the fuel pump is working or not, it might have broken. Good luck, let me know how it goes!

You ran out of gas so you probably picked up crap off the bottom of the tank into the filter so check or just replace the fuel filter first.

Transmission not going in park

It was a 10 amp blown fuse located in the passenger compartment fuse box in the truck. Fuse number 14. The brake on/off switch fuse. Weird, but we switched the fuse and its works like it never had an issue. I believe the trailer harness blew the fuse.
unit 14 from United States 2 years ago
So the 10 amp 3 prong fuse that kept blowing and wouldnt let the truck shift. Happened to be a short behind the glove box. Check all fuses and trace your fuse lines.

Well you can have moisture in your fuse box for some reason like I did but that's because my windows of my vehicle were leaking and the truck was sitting for months but if any kind of moisture got in there it could cause it not to work

Fuse or transmission

Knuth from United States 8 years ago
Fuse 23 powers a lot of sensors and actuators: the torque converter clutch solenoid, electronic pressure control solenoid, shift solenoids, etc. I've seen this problem before: check the wiring harnesses for all four oxygen sensors for heat or chafing damage, and the wires going to the transmission too. Since the fuse is blowing there must be a wire damaged and shorting to ground or one of the named sensors/actuators is shorted. Good luck, let us know when you solve it!

If the sensor actuators are used in any way to power up alarm system ,could be many reasons why truck won't have power and keep blowing. The fuse sir

Working, you can feel heat but no air is being pushed out this is after the truck has been parked overnight and sits for more than 7 hrs. Once I drive it for 30 min or so and start back up
Then the heat will blow out the vents and floor... Dealer said it may be a dead battery cell??

Have you checked if the air is coming out of any other vent? Maybe it's a problem with the air flapper. Can you get cold air? If not, check the blower motor, although it's weird that it starts after a while.
