I've got a 2005 f350 with a 6.0 starts when it wants. I have checked the ficm and 48 volts when key is on and cranking! How do I know if my icp is bad? Some days it will start no problem but most days it will just crank over. When it does start i run it for a while shut it off and try to restart it and it wont!

I recently purchased this 2003 F350 DRW with the 7.3L, automatic trans. Truck has 140k on it. Three times now while the truck has been idling, the engine just died. The first time was a couple of weeks ago when I was pulling out of the driveway. Then again yesterday twice, once while just sitting at a stop sign. Each time it has started right up and ran fine.What is going on here?

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?

My buddy's 2001 7.3L F350 has had 3 transmissions. Rebuilt and used. Once the new trans is in he goes like 15 miles and then is starts shifting hard and grinding gears. What this could be?

I recently bought a 2001 f-350 xl 4 door with the 8 foot box it has the 5.4L triton v8. I was heading to a job up in northern Alberta about 10 hours away from where I live. On the drive I lost control of the truck on some black ice I was doing about 50 miles I went into the ditch but nothing crazy drove right out after. Now my truck won't do over 30 mph the engine starts to sputter and back fire I loose all my power, what's going on. At idle she revs fine but as soon as I put her into drive it's like she wants to die what can it be?

I have a 2000 Ford-F250, V10, 6.8 liter Gas. The issue is that when I try to start the vehicle it will start, but then start to idle real low and then die. If I try to restart sometime it will and sometimes you have to let it sit. I can also pump the gas and it will sometimes start.

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?

New too my Ford, but anyway it's -10 Celsius. My trucks been idling for a few hours and probably will all day because of my job. Usually idles about 600rpm normally. So today the oil temp was about 80degrees Celsius. Then the truck idled up too about 1000rpm for a while. If I touch the gas it goes back to normal idle speed but then starts idling up again after 30 sec. What temp does the truck want too keep it at?

I have a 1999 f350 7.3 diesel. If I apply the brakes when I am not moving it is almost impossible to move the steering wheel. I have flushed power steering system. This problem has gotten worse over the corse of owning the truck for the last 10 years. Ball joints and u joints are good. Had to change power steering cooler a few years back, rusted out line, really got gradually from there.

I have a 2002 F350 with a V10, this just started happening where at times the truck will turn over but won't run... after a few times of trying to start it I pull the key out let it sit for 5 seconds then put the key back in and runs perfect..... now at the gas station the other day it started but ran like it was on 4 cylinders... I turned it off and restarted it and runs perfect. Heading to Kansas next week to pick up my boat and don't need problems....

I have a 2005 F350 diesel, 54000 miles. I was at a red light today, engine is idling normaly.. light turns green and I step on the throttle and get nothing. My truck is rolling (in drive) as if it were in nuetral. I shut the engine off and it does not start for 10 to 15 min. Then it fires up and seems to be running as if nothing happened.

2001 f350 v10, initial problem was when i came to stop at light it idled rough. I changed all plugs,injectors and COP, and bad connectors thereto. Changed the clock spring as well. Now the truck idles like crap at first start of of the day then run fine there after. Replaced IAC, TPS, Temp sensor. Condition getting worse and now the temp gauge does not work. I am thinking maybe CAT Converter loaded up?

I bought a 1999 f350 v10 about a month ago took it on a 1200 mile trip from Arizona to Kansas. Truck ran great till I got Kansas. The truck started to lope after I got fuel at a fuel station. Did not get any check engine light on. I check for vacuum leaks did not find any. I change all the coil packs, spark plugs, IAC valve and fuel filter. Clean the intake and put sea foam in the fuel tank and the truck still idles rough. Change the egr vavle. Truck ran great till I got 10 miles down the road then the truck started to lope again. So I'm getting really frustrated over this truck.

I would like to do the high idle mod with my 2006 F-350 using the upfitter switches. I've seen a couple of threads about this but they are not real clear to me and don't mention the 2006.

Alright, I have a 2002 f350 7.3 4x4 ext cab xlt with 300k miles. Bought in may 2016 with 260k miles and towards November started running rough and felt like a loss of power. Had a no start but a new gray cps fixed that issue. Running fine. About a week later started it up and it had a rough idle, felt like not all cylinders/injectors were working. Was "knocking" and a loss of power. I was in the army at the time and stationed in Georgia, took it to a local diesel shop in Georgia and they confirmed my icp sensor was bad and injector #1 , #5 #7 were bad. Work was busy and money was scarce so I left it as it is and was saving up to buy the new parts. Then one day approx a week after the visit to the shop, I started the truck up and it ran fine. No misfire no knock no rough idle, drove fine for about a month.
In December, I was on vacation in florida to see my parents, drove the truck down, ran fine. While on vacation one day in a Walmart parking lot the truck didn't start up. Couldn't fix any issues then so towed the truck to my parents house. Did more troubleshoot, replaced fuel filter, cps, ipr valve, icp sensor, glow plugs, glow plug relay, ebpv pedestal was replaced with a ebpv delete pedestal. All parts bought oem and/or from riffraff diesel. Still would not start up. So then I bought a refurbished IDM from eBay, oem and then the truck finally started up one day but running rough again like it used to, then it wouldn't start again. So then, I replaced the PCM with a reflashed/refurbished one off eBay and boom truck started up, still running rough but now it starts up every time.
Now, took all eight injectors out and replaced all the o rings. Cleaned them up and put them back in, truck still running rough. Injectors didn't appear damaged nor the wiring harness so now I bought three reman injectors from riffraff. And replaced those three bad injectors. One of them is not spitting oil out the oil spout on the injector.
My dad has worked on freightliner semi trucks for years and is fairly knowledgeable when it comes to diesels. However he did something very amateurish the other day. So two injectors were installed while we were still waiting on the third in the mail. He wanted to see how the engine reacts when that one bad injector was not in play, but instead of unplugging the injector under the valve cover, he cut the wire outside the valve cover to the injector. He stated it's not a big deal and he can solder the wires back together. But once he cut the wire, the truck sounded a lot stronger, still rough idle but definitely stronger. Before, you would be pedal to the floor and the truck barely moves forward but now the truck will lunge forward. A big difference in power.
Now today, third injector came, swapped them out and fired up truck. We didn't solder the wire yet just quick connect, same you would use to connect wires for a car stereo. The new injector was not spitting oil out the oil spout. Even at high rev and truck warmed up. Truck still runs better with that one injector unplugged.
Tomorrow we will troubleshoot if somehow there's wires that grounding out or burnt out somewhere but as of right now everything seems to be in order, the uvch are tight, and no signs of anything burnt.
Triple checked everything, still getting fuel pressure, still getting oil pressure what gives? I also replaced the MAP sensor. Fuel pump is fine, fuel gets to fuel bowl. The next thing I'm thinking is maybe the hpop but we have oil pressure so idk..

I have a 2002 f350 5.4l that has stalling issues, first some back round. Last week I pulled up the a stop light and the truck stalled I figured it was a iced fuel line as it was very cold so I put a bottle of drygas in the tank. Evidently there was a lot of moister in there because as soon as I started the truck check engine light came on and truck would not idle at all. I got through that tank and am now on my second tank. It is better but the truck will still stall when stopped at light (has never stalled in park or on the road only while stopped in drive) the check engine also light went off halfway through the first tank. What next?

I have a 2004 5.4 power f350 that makes a fog horn pitched howling sound at idle. First instinct was a pulley. Started it with belt off and its obviously something else because it still made noise. Traced it down to a resonating sound from the intake. Specifically the hose from the IAC to the air cleaner.
From some googling, i decided to change the IAC. No real change. So I took off the resonator tube and thoroughly cleaned it, took off the throttle body and cleaned it, took off the top snout part of the intake and cleaned that put in a new air cleaner (the glue was separating on the old one) and reset the battery. Still makes noise at least 85 percent as loud as when i started. Am I missing something?

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...
