Ford Super Duty (1999-2016) :: 2006 F350 - Long Cold Starts / IPR Is Maxing Out At 85% On The Gauge
I have an 06 F350 6.0 and I am having long cold starts. On the gauge the ipr is maxing out at 85%. This only happens when cold and have never had a no start issue. When hot the engine cranks right up and the ipr stays in normal range. FICM has been replaced. Does this sound like needing a new ipr only?

I have 2002 F250SD, The horn just starts blowing by itself. Bump the horn switch and it stops for a couple of weeks. I've looked at the wires to the fuse box and no wires shorting out the horn wire. I read some very old posts but nothing conclusive was ever decided on, just a lot of guessing. The horn switch has always been sensitive.
Somebody said the air bag is warming up in the sun and expanding causing the horn to blow. Somebody said the horn relay, but in 55 years of working on trucks, I have never had a horn relay act like that. I'm told the horn relay is built in the back of the fuse box and it all has to be replaced. Some say the clock switch. I don't know what that is or where it is. I guess inside the steering wheel. Is it hard to replace?
Where do I go from here....
Ford Super Duty (1999-2016) :: Engine Starts To Run Very Roughly Then Will Die
I have a 2002 F-450 crew cab 2wd automatic 7.3 diesel with 298k on the body and about 120k on a Jasper engine. About a month ago I started it in the morning to let it warm up. Went to make coffee. Came back and it had died. It was low on fuel and I didn't pay attention. Played hell getting it primed back up. Now if I don't let it warm up for twenty minutes it won't run worth a flip and has been dying out. Changed fuel filter. Unplugged ICP. No change. When I crank it it will turn over for about thirty seconds then oil pressure gauge moves, then engine starts to run very roughly. It will die. I repeat a few times. It will eventually start and start and stay running. Blows whitish grey smoke until it warms up. No loss in power till CEL comes on. Still not too much loss. Sometimes it takes a long time to get it running. Sometimes it will die after I get out of the driveway if I don't let it warm up. Truck was serviced maybe 3000 miles ago. No water in fuel. New fuel filter. New air filter. It is a company truck. I work for a small company building cell towers.

I can't seem to get the engine temp to middle range on the marker, but yet my heater blows "to me" hot air. Even while sitting in idle for extended amounts of time I cannot get it to "operating" temperature. I would think if my thermostat was stuck open my heater would blow either cold or slightly warm air. I have the 5.4L engine with knn air filter and no cats.

My 06 f350 power stroke has a viper 2way remote starter.
When I try to start it when the truck is cold it doesn't crank long enough for it to start the truck. It will try 3 times when I hit the start button and normally won't go. It almost starts most times but stops cranking right before it starts. This is driving me nuts.
I just tried 3 times to start the truck and it in ally went on the 8th time trying to crank.

Ford Super Duty (1999-2016) :: 2001 - Cranks Strongly But Starts Intermittently?
I have a 2001 F350 V10 Crew Cab that has 51000 miles on it so it doesn't get driven all that much, but I do start it at least once a week and it has always started on the first crank.
A couple weeks ago I drove over a friends, I backed up her driveway, turned the truck off and went inside. After returning I went to start the truck and it wouldn't start, just cranked. Probably had between 1/4 and 1/2 full.
I let it coast down to the level and it still wouldn't start. Finally had it towed home. When I got home I tried it and it started right up. Next day it just cranked and wouldn't start. The day after it started right up, I ran it for 20 minutes, turned it off, tried to start it and it just cranked....
Then I started looking at forum's for a possible answer.
I already had an IAC that I bought a few months ago since it was idling a little rough that I installed. Still started intermittently.
When I listen closely when I hear the fuel pump run when I turn the key it starts right up, when I can't hear the pump it won't start.
I have tried moving the relays around that are in the fuse panel on the drivers side hood, moving the fuel pump one to the blower motor and vice versa. Still starts intermittently and only when I hear the pump run.
I looked for the FPDM that in some trucks is up by the spare tire but apparently my truck doesn't have one, or at least in that location..
My next thought is that it must be a bad pump...Can a bad fuel pump act like this, sometimes work and sometimes not?
Ford Super Duty (1999-2016) :: 2003 F250 5.4 - Starts Cutting Out When Under Load
About 20 miles into it, and it starts cutting out on me under load, over about 1/4 throttle. I baby it a ways further, and park at a wal-mart. Idles fine, but once again, after 1/4 runs like crap, acts like it's back firing through the intake spit and sputtering. Have the wife come pick me up since I was heading to work. Decided to shut it off, and restart, and it acts like its never had a problem.
Was messing with it today, and let it warm up in the driveway. Once it got hot, same story good 1/4 throttle, past that, not so much. Shut it off, started it back up and drove it to see if there's any codes at vatozone. Drove good (laying into the throttle) for about 2-3 minutes, back to same behavior. Hooked up code reader, no current codes, and no historic codes. Although I did notice (actually since I bought the truck) that the check engine light never comes on, even at initial start up. Looking at my spare cluster, it's an l.e.d. So no bulb out I guess unless the led is bad. Truck has around 130,000 miles on it. Everything is stock.
I'm leaning toward a fuel pump, a clogged cat, or a fuel pump relay or cutoff switch problem.. It doesn't have any other issues than that, and has been a good truck for the 10k miles I've owned it... 2003 F250 5.4...
Ford Super Duty (1999-2016) :: Speedometer Starts To Climb Rapidly To 100 MPH Then Stops And Goes To 0
I have a 2002 F350 v10. I have 101,000 miles on it. When the Speedometer hit 15mph it starts to climb Rapidly to a 100mph then it stops and goes to 0. My miles go blank and when I slow down to around 5mph it comes back. I do know that I have a bad clock-spring and am changing that this weekend.

Simple enough the truck starts then after about 30 seconds it bogs down and dies. I am getting these codes.
705 Transmission Range Sensor Out of Position
708 Transmission Range Sensor Circuit High Input
720 Output Speed Sensor Insufficient Input
743 Torque Converter Clutch Circuit

Sounds to me like the converter it locked up. What do you think? Its a 5.4L

I just recently bought my 2002 F250 Lariat with the 5.4 and 76 thousand miles. I love this truck but I've started to notice a few things with it. When i go to start the truck it sometimes starts but then instantly shuts off. When i try it again it takes a long time to crank over. This has happened in cold and warm weather. What the problem could be and things i could do to prevent it?

2013 F250 4WD gas V8, auto, stripped basic truck, 72500 miles.
I'm driving back to the shop today, chimes start going off, Service Advancetrac comes up where the odometer is & starts flashing. More chimes, airbag, battery, seatbelt & a couple of other lights start flashing, & coming off & on at random. Check Brakes starts flashing where the odometer is. This gets worse & worse, more & more noise, but the truck runs fine, starts & stops fine.
Ford saw fit to not put a volt meter in, so I don't know what the battery was doing. This went on for at least 5 minutes. I finally was able to push the button to turn off the Traction Control in the split second when all the lights went out. With Traction shut off, all the noise & flashing went away.
Ford Super Duty (1999-2016) :: 2008 5.4L - When Slow Down To Idle Engine Starts To Diesel
I've got a 2008 5.4L I just bought. The previous owner just ran around the city and never pulled anything with it. After the truck has been pulling and the engine is hot, when I slow down to an idle the engine starts to diesel. This lasts for a few seconds then goes back to normal. Is this just because the engine isn't used to working and the computer hasn't adjusted yet? is this something that could be serious and I should have checked out by a garage?

I have a 2000 F-250 Diesel that has started acting strangely. It starts and runs well, but every once in a while the peddle just stops working. Might be a second or so and then the RPM will go up. Or you may be running down the road and all of the sudden it just stops acting like it is getting enough fuel. Same thing it might last a second or so. Sometimes it might happen 4-5 times in a row over a few minutes and might not happen again for a day. Truck does not stall when this happens. It just does not go like it should.
View 1 RepliesFord Super Duty (1999-2016) :: 2001 F250 Occasionally Starts - Fuel Pump?
I have the gas 5.4l in my 01 F250 Super Duty. I had to change out the leaking Heater hose before I could attack this other issue. The truck starts when it feels like it. I changed the fuel filter and it started fine. Then the next day it wouldn't. Later it would. However each time it does start it dies when throttled up. I am down to thinking it is the fuel pump. My question is, because changing the pump sucks about as bad as changing the heater hose. Can I install an inline fuel pump and deal with the sump pump in the tank later? Are there any Cons to doing this?

My truck is 2001 F250 with the 7.3 I have AFE intake, TS 6 position chip, Stage 1 Auto Tranny, 4in Exhaust all the way down. New glow pugs as of last week as well as uvchs and gp relay. Also has a new hpop line. New compression sleeves for fuel lines, riff-raff fuel banjo bolts and fuel pressure regulator.
I am having a hard start issue no matter what the temp is outside, unless it plugged in. Once it starts its good unless it sits for more than 5 hours.
Batteries have tested good, glow plugs ohm at 1.3, gpr 12.83 at batt side- once on it 11.9. All fuses are good. HPOP res is showing at about 3/4" down from top.
***Wires going to the MAT sensor are showing through at the connector, not sure if this could be a problem...if so why???
****Noticed some oil in the ICP, cleaned and unhooked will check start tomorrow to see if this works with long start as truck is plugged in.
Will also be putting a new fuel filter in and double checking oil level in the am. I do not have a scanner tool and am doing the best I can before I take it in to ford to diagnose.

View 1 RepliesFord Super Duty (1999-2016) :: 2003 F250 Starts / Barely Bounce Off Zero RPMs And Die Out
I have a 2003 F250 with the 5.4 and I believe I am having a fuel delivery issue. I took out yesterday and stopped to get a drink at the gas station, came back out and the truck wouldn't start long enough to idle. It would start, barely bounce off zero rpms and die out. I checked the fuel interia switch and it was down. I tried turning the key back and forth thinking it might reset the fuel pump or something and that didnt work. I get the truck towed home and couldn't get it to start last night. I go out this morning and it starts, come home from work and now it won't. This happened about 2 years ago and I never did anything about it, but it took 2 years for it to happen again.
