Ford F-150 (2004-2008) :: 2005 XLT Does Not Always Start
Dec 29, 2011
I have a 2005 F150 XLT 5.4 that doesn't always start. I've been having this problem for over a year now.
Sometimes it will start, but sometimes it won't. Seems about every other, or perhaps every 3 days it just will not start. Then, if I wait a few hours, it'll start.
I've replaced the fuel pump, fuel filter, mass air flow sensor, fuel pump driver module, starter and the battery. None of this has seemed to effect it.
Lately I've found out that if I put the truck in neutral, then while cranking I go to park (going through reverse) it will start. Sometimes not on the first try, but after a few attempts it will start.
It should also be noted that when it does start, often it'll make some loud noise RIGHT before it starts up. Sounds kind of like the starter grinding. If it doesn't make the grind noise, the other thing it may do is all the lights and everything turn off for an instant (half a second) then come back on and start.
I'm really lost as to what to do. I've been thinking that it may be the transmission range sensor, but I really don't know. I don't want to keep spending money replacing random parts, in hopes of fixing it. I'm on the 3rd starter, because of all the cranking I have to do when it doesn't start.

i have a 2005 F150 5.4L while driving my message board bell indicated low oil pressure i pulled into the station and checked oil. i had to add about 2 qts i filled up with gas and the truck has not started since. I towed it home changed the oil, filter, oil pressure sensor and the fuel filter
when i try to start it the engine turns over normal no noises, knocking or anything out of the ordinary. It sounds like it wants to start but then acts like something is shutting the fuel pump down. I had the local mechanic tell me that the fuel pump was out. I can here the fuel pump kick on for no more than 2 seconds then shuts off. he told me it should pump for about 5 to 10 seconds. i am not convinced it is the fuel pump dont want to spend $300 on something i dont need.
is there a saftey cut off swith to the fuel pump when the low oil pressure indicator comes on? i also check the codes and its not giving any codes but i had removed the battery and replaced it and i am thinking that removed the codes?

My 2005 cranks but will not start. I spray starter fluid in throttle body and it will start but won't stay running. I've replaced the fuel pump and the fuel sender unit which is located under the spare tire. After I replaced the fuel sender unit It started and ran for about 30 seconds. It quit when the fuel line popped off the fuel pump and pushed gas all over the ground. I secured the gas line back on and now it won't start again unless I use starting fluid.

I drive a 2005 F-150 XLT with a 5.4L engine in it. This problem only happens after I have been running the truck on a small trip (15-20 min), stop to get something, and then 5 min later start the truck up, and this is the feedback I get.
-Sometimes it barely cranks, idles for a second and then cuts back off.
OR
-Takes much longer than usual to crank and get's going fine.
This is the only time it happens, upon restart after driving for a short period.

My 05 f-150 Supercrew 5.4l, will start for a second and then die. I can sometimes feather it and rev it up, but it dies as soon as you let off. I changed the fuel filter and while we had the lines off we turned the key on and it pumped fuel but only for a few seconds. Shouldn't the pump run constantly with an open line?

I have a 2005 STX with 107,000 miles on it. When it is cold you have to turn the key on for 5 seconds twice then start it. When it is warm it will start like it always did. When the temperature outside is 60 or above you have to do the key thing about 5 times. I think it is my fuel pump...

Brought a 2006 f350 6.0 from the action and knowing it was damaged from the frame, i went ahead and brought a another f350 6.0 2005 from someone around town, the last owner is calming the truck was stole, and most of the engine was stole, and the windows where damage. ( I just wanted to buy the truck for the body so i can transfer the engine to this one! ) but instead of switching the engine, me and my dad went ahead and only put the missing parts back onto the engine....
I can tell the last owner wasn't telling the truth, and me and my dad where thinking the last owner made up his own story about the truck being stole !! I did a vin check and noting came up about having a bad history!!!!!!!!! I'm thinking something went bad in the truck, and the last owner did his own fault story... Anyways!!!
we finally put everything back in place, and the truck cranks, but does NOT start!! and also has no spark. sometimes it sounds like it does wanna start!! we check the fuel, and wires, oil, fuel filer! everything good, but the truck has no spark, and where not sure if thats the problem. and also switch out the Crank sensor. Still no luck!!
And also there is smoke when we crank. battery are good too, and even left the truck 28 hours on the wire to head up the engine!!

2005 5.4L She would have a hard time starting before but after I replaced and fixed everything below she was running really good. Now back to sputtering, taking a long time to start and now not starting at all.
I have replaced; Fuel Pump, Fuel Filter, FPDM, Plugs and COP's, FRP Sensor, followed the power wire from the FDPM and found it corroded bad so I replaced it, also changed the ground location on the FDPM, I have checked all the wires from the FDPM to the drivers seat, checked all fuses.
I have power to FPDM and I have the diagram for the plug but how can I test (hotwire) the Fuel Pump without lowering the fuel tank? What should be the voltage coming from the FPDM plug? not sure about pin 1 & 6.
How can I test the FRP sensor? what are the specs for voltage?

My 2005 SuperCab 5.4 4x4 won't go into 4wd...I turn it on and nothing! No light, no clunk, nothing! (No 4Low either). I checked all the related fuses and relay fuses behind the passenger kick panel, and they are all fine. I don't do any off roading, nor have I ran anything over. The truck only has 20,000 miles on it.
I did have the brake booster hose recall a couple years ago, so I'm going to crawl under to see perhaps the technician didn't click a harness back together or something.

I've got a 2005 F-150 (5.4 triton) with about 35k miles that I rarely use in 4x4 mode. The other day, after stopping to fill up with gas, the truck 4x4 Lo light was on after starting it. The dashboard switch was still in 2H mode as I never switched it. I first thought that the dashboard light might be in error, but when I began to pull out of the gas station. the truck was in fact in 4x4 Lo. I had forgotten how to cycle it back to 2H so I slowly drove about 3 miles home at 20 mph.
Once home, I re-read the tranny sync sequence and managed to get back to 4x2. I called the dealer who never heard of a truck getting into that Lo mode w/o activating the switch and suggested that I just monitor it. I read a number of forum threads discussing the IWE and solenoid problems, but all of those threads dealt with issues of not being able to get too 4x4 mode. My biggest concern is that I leave in a month for a 2000 mile trip, towing a cargo trailer and I'd hate to inadvertently switch into 4/4 when traveling 60 mpg on a highway.

2005 f150 4.6l up on jack stands right now with the oil drained and a few bolts out of the oil pan. It looks like I have to take the cross section out to get this to even move but I don't know if that's going to be enough. I'm sort of running trial by error here but hoping I don't do something I cant put back together. I'm assuming ill be okay to take the cross section out but I don't know if I need to move the differential to get it out. My oil pan gasket is leaking and I'm trying to replace it.

My F150 4X4 would not start a few days ago, after only having turned it off a few minutes prior. The gauges would sweep wildly and get stuck at various positions. I checked the fuses and they were fine, then unplugged the battery for a bit and it started back up. Occasionally it won't start and i'll have to disconnect the battery again to get it to start.
I'm still having some strange electrical issues though. The radio no longer turns on unless the ignition is turned to AUX. My back up alarm for going in reverse doesn't come on anymore. The gauges take at least 10 seconds to wake up after starting the truck. The dashboard blinker indicators will randomly stop blinking or making any noise. I was thinking it could be the computer, but could it be something else?

I'm having an issue with my 2005 f150 xlt. Its been happening for almost near a month and still cant locate the issue .
It has a vibration at 75km throughout the whole truck. Ive tried multiple things done to it by a mechanic, such as having the tires balanced and the ujoints replaced. The problem still persisted and after attempting to test out to see if press/releasing the parking break (my mechani suggested trying that out), my driveshaft fell off.
Apparently the center bearing snapped and cant simply be replaced on the 05's. So i had to get a new driveshaft installed (used, both the 3 mechanics I've gone to say its in good condition).
Even after replacing the driveshaft the issue persists - however it seems a bit softer than it was (I am guessing the old driveshaft was worn from the vibration causing it to be worse). After that I took it to another shop to see if they could locate the issue. They did a driveline inspection and engine inspection too see if a misfire could be the cause.
Again, nothing was found. The only thing they were able to find was that the issue only happens under load and slightly occurs at 40 and 100km as well (although alot softer then the one at 75) and they say they cant find anything physically and it was a mystery to them.

my 05 f150 5.4 with 76,000 has a weird rumble at idle, I don't think its a miss and there's no codes and when I put it in park it goes away or if the idle changes just a little you don't feel it. And you feel it through the brake pedal the most its not real bad butb enough to bother me.
