I changed the IAC valve 2 months ago because my truck kept stalling when idling down on a cold start and that fixed the problem. A few days days ago when starting it started revving to 2 - 3 K and won't IDLE down now? I changed the IAC again and that didn't work. What else should I be looking at to stop it from revving so high?
2001 F250 5.4 111,000 miles super duty.
Cold no start goes nowhere. I have a 2001 7.3 that will not start in the cold if I forget to plug it in....like last night. I have to plug in the block hater and give it a while before it will start. I tested the glow plug relay,it works fine. I can not find a test for the fuel bowl hear, and I'm not one to throw parts until I accidentally fix it. Any test procedure for the fuel bowl heater? Why this POS is so bad in the cold? Glow plugs tested fine at diesel shop in December, and this problem has been around since before that.
View 14 RepliesI have a 2001 F250 V10. It idles around 1k and when stopped at stop lights or when put in reverse it stalls. I have replaced IAC, fuel filter, tranny filter, oil filter, plugs, coil boots, tranny fluid, oil, air filter, and PVC along with the PVC hose. I'm totally stumped. It doesn't stall if I do a rolling stop.

When it's cold out it won't start at all I have to use starting fluid but once started it will start right back up. Did the plugs fuel filter cleaned the intake and sensors still have a problem plenty of fuel pressure plenty of cranking amps brand new battery and Alternator. It just cranks and cranks when it's warm out fires right up. Runs smooth no lack of power or misfire no codes are being thrown also.
View 14 RepliesI have a 2001 7.3 ford the seal in the turbo went and oil went in the exhaust. lots of oil like 10 quarts. I had a rebuilt turbo installed ran great for 2 weeks then one day out of the blue started idling rough and then downward from there no power stalling etc I have my super chip scanner it read dtcs of 1249 478 1211 and 238. Is it possible the muffler is plugged with oil? or is it and ipr? 193000 miles....

View 3 RepliesMy 2000 F-250 6.8L V10 has a choppy idle during the first 30 or so seconds after a cold start up in the morning then it smooths out and drives perfectly. If I were to place the truck in gear during the choppy idle, it would not die and throttle response would be fine.
I cleaned the MAF sensor and checked the PCV elbow for cracks (no cracks). It idles at about a 1000 rpm during a cold startup then drops to about 750 rpm according to the dash tachometer. The truck has 187,000 miles on it.
So, I have a 2007 f250 with the 6.0. When she's cold she starts fine but runs rough like she has a miss. When she warms up the miss goes away and it runs pretty good. But if I shut it off it won't start for about an hour or so.
ICP sensor has been replaced.
FICM is putting out 50v
Just bought a 02 f-250 7.3 with 115k miles. A couple days after I bought it I noticed a lot of white smoke on cold starts for about 20-30 sec at 50 degree temperature. So I tested the GPR which ended up being bad a replaced with the one that is double in size(name escapes me atm) and also did the 50 cent mod to keep the through-valve cover harness from losing connection since both sides were lose.
After that the temp warmed back up and it would only blow a "puff" of white smoke. The past two days it has gotten down to 30-32 and the truck has a rough time starting. Cranks fine but it's almost like it's getting choked or flooded then it will blow smoke for 3-4 minutes after it starts. The truck does have a FASS fuel system on it with stock injectors. Should I try to Ohm out the glow plugs again or where should I start trouble shooting?
I have a 01 f350 7.3 turbo dsl. will not start cold. engine turns over fine. plug into block heater over nite , will start! outside temp does not make difference. I have replaced glow plugs, glow plug relay, wiring harness under valve covers. Where to go from here?
View 14 RepliesMy '01 f250 7.3 has gotten hard to start. It seems to maybe be due to cooler weather, but not always. I have been told that there is some sort of valve in the fuel tank that could possibly cause this when the fuel gets around a 1/4 tank or so. But, it's doing it at any fuel level. But it doesn't do it all the time. I do notice it more in cooler weather. Anyway, when I try to crank it, I'll let the "wait to start" light go off and then wait a bit more. I'll turn it over and it almost as if the batteries are weak.
I'll stop and give it a few seconds and turn it again and it will normally start. But sometimes I'll do this 5 or 6 times and it will finally fire. But the more I have to try, it's like fuel builds in the cylinders and it smoke like a coal train for a minute or so. Almost like gas motor that has been flooded. But the smoke burns off and it runs like a top. I was thinking the batteries may be weak , but sometimes the starter will spin the motor with no trouble at all. I'm at a loss. Is it possible for fuel to drain from the system causing it to have to reprime itself? Here lately the smoking has me concerned even though it clears up.
My 2001 F250 will not start (clicks). I verified its not the battery and even tried to jump start it. I have never replaced a starter- but before I do that I read where there is another solenoid under the hood somewhere. I always thought there was just the one on the starter itself.
Two questions:
1. where is that other solenoid located and should I replace that first?
2. How difficult is it to replace the starter? I am pretty handy.
The issue is that I cannot get it towed easily - I just need to get it started at least once since my plow is still installed and it's hooked up to a trailer..
My 2001 6.8 L V10 runs great all day & night without issue, but first thing in the morning when below freezing it has a hiccup. It'll fire right up and stutter and stall within less than 2 seconds. Usually twice. Third time it fires and keep running. Is there a fuel check valve somewhere on this thing? Not sure what that would have to do with the temps. Wondering if it's/there's an easy fix or not?
View 5 RepliesI have a 2001 F-250 XLT 4x4 with V10. Truck will not start. No fuel pressure. My Haynes manual does not show ignition or fuel delivery wiring. I have found the relay box behind the radio/dash. I need a wiring diagram and info on which relay is the fuel pump relay. Want to know so I can jump relay to see if fuel pump is okay.
Truck had sat for a few weeks being ran very little, so had to jump start yesterday. Ran for about 15 min, the shut off, re-started and ran for 30 min. Truck sat for about 1.5 hours then would not start. Charged battery overnight and it is 100%.
Truck was dead- 2001 F250 V10... Has a starter relay (solinoid) behind battery... put a new relay in there- no go- cleaner terminals... then I put key in start and shorted the 2 terminals in the relay and she cranked right up. That would mean the starter is still good correct?? something in the ignition system?
View 1 RepliesI bought my son a 07 F250. 5.4L and he tells me it is dying on him, it started out with it trying to die when going into reverse, now he can't keep it running much at all. He took it to the Firestone shop and they are telling him one of the camshafts is probably bad... I highly doubt it. And a new 3k motor is what he needs...
The truck has 145k on it and has been well maintained and just had the oil and fluids changed. Air filter is good, battery is new as well. Only thing I can think of is to clean the throttle body and air meter, he lives 200 miles away so it is hard to troubleshoot over the phone. Any pointers to look at? possible vacuum leak somewhere?
I have a 2001 Ford F-250 with the gas v-10. Yesterday it started just fine as always. Today I get into it and it starts to turn over just fine then starts to make a grinding sound and the truck won't start. I have had a fuel issue in the mornings with once it started you had to barely press the gass to keep it running. But never makes a funny sound and always runs fine. This only last for a couple of min and then it runs fine for the rest of the day. The grinding is not the starter. I took it off and had it checked and it was fine.
The truck had been using oil. When I checked the oil level it was low but it was still on the stick. "I know a motor needs oil to run smooth but it's my dads truck and well let's just say he is not the best on maintenance". Also I smelled the oil and it does have a gas smell to it. So it definitely does have some gas in the oil. I tried to light the dipstick with a lighter and it wouldn't light. So not sure how much gas is in it but that's what I did.
So the question is, would something just in mid crank go bad and then not let the motor crank. Truck made no weird noises before this so I find it hard to believe the barrings just went out in mid crank and now it is shot.
Also I just checked compression on front cylinders.
Driver side read 75lbs
passenger side read 100lbs
2001 F250 5.4 ... I'm losing my mind chasing a Gremlin. I've been having mostly intermittent starting issues with my truck. I've had the truck for a little over a year, after someone totaled my previous one.
It occasionally wouldn't start on the first attempt, but it got really bad in the last couple weeks.
I first thought it was a faulty inertia switch or wiring in that vicinity, as at one point after manually tripping and resetting the cutoff switch it would start, UNTIL I put the trim panel back. At this point I think that may have been a coincidence.
I eventually probed the switch and it tests as it should electrically.
I put in a new fuel filter and things were fine for several days, but it acted up again. That time was last Saturday. Got it to start and all was good until tonight. Now it won't go, and I've tried so many times that I can see the battery power is dropping.
Last Saturday I pulled the relays from behind the radio and cleaned 'em up real nice. Also, just to check another variable I swapped the two that matched.
I'm about ready to change the fuel pump, but I've heard so many people say they did that but the problem was something else. Not only will it costs hundreds of dollars, its cold out and we'll have to drop the tank in the driveway.
In addition to the relay, inertia switch and fuse, I have found some mention of faulty fuel pressure regulators causing issues. I'll pry the vacuum line off in the morning to see if I can detect fuel residue on the vacuum side. (There is some noticeable corrosion on the fuel rail in that area).
I REALLY want to make sure I rule everything else out before spending hours under the truck in freezing weather dropping the tank and changing the sending unit out.
On key-on there is a noise from the gas tank, but someone else listening described it as a click but no whirring.
I do hear the relay clicking behind the radio. (Also, I pulled them again tonight and put a meter to them. With 12V on the primary side, they click and the other side shows continuity on diode check, and about .2 Ohm on resistance mode.)
I went through a lot of trouble to get my spare out looking for the fuel control module before finding out my truck is about 3 years too old to have one too. What else to check?
Been driving my 2001 f250 7.3 4x4 with no problems then started noticing it lacking power so I changed fuel filter and air filter. After a week goes by I was at work and I was leaving to come home so I started truck to let warm up and it cranked longer than normal but started. Let run about 10 minutes idle nicely when I punched it it bogged down and had no power never died. I idled over into parking lot and power came so I took off again loss all power again, still never died. Got it right back to my work sat there a bit and tried again this time I took it easy and was able to get my truck home 30 so miles.
When I got home I ran codes p1211 came up for the icp sensor I changed it did not change anything still had same problem. This was a Saturday afternoon to evening issue. So sunday I played around with it just checking out info online and test driving it seem to run ok but still lacking power. Let it sit till Monday I went out to start it had to cycle key 3 time before it started idle nicely then died would not restart changed ipr valve nothing changed cam sensor nothing changed some how 10 quarts low in oil just changed dec. 30th don't know ? Now will start if I pump throttle and has all its power back?
I just purchased a 2012 F250 XLT with the 6.2. It has 38,000 miles on it. Yesterday I noticed, when coming to a stop, the idle will sometimes drop below 500. The engine will stumble a little, then the RPM will jump up to 1,000. Twice it has stalled on me. When it stalls, the engine will restart just fine. No codes in the computer or warning lights on the dash.
I will be bringing it back to carmax, as it is under their 30 day warranty still. Hopefully they will be able to figure out something. I am thinking either the TB needs to be cleaned, or there is an issue with the canister purge valve. I saw the TSB for the CPV but it doesn't cover my truck.
I have an 04 F250 4x4 king ranch with a 6.8 V10.
When I first bought this truck it had a problem of stalling out at stops. You could sometimes hold the brake and gas and push your way through it but it would sputter for a second and try to die and then it was fine once you got going. The OD light would flash, check engine light would come on and it would throw a P0720 code for the OSS. I did some researching and I pulled the sensor in the pumpkin before that because I read that could cause the same problem, so I cleaned it and put it back but it didn't solve the issue. Then found that an K&N air filter can often times clog the MAF and cause the issue so I pulled my air filter and sure enough it was a K&N, I swapped it with a normal filter and sprayed some MAF cleaner and its been running like a top for months... until now.
It started again, gradually at first. It would die when I started to back the truck at a very low speed to load my 4 wheeler. I fired it up and it was good again for a couple more weeks, then I went to hook to a horse trailer and I was having to back up a hill to get to it, and it just kept dying, OD light would flash, check engine light came on. I was in a bind so I just tried wiping off the MAF with a rag, that didn't work, my girlfriend was using the truck and said it kept dying whenever she stopped. I got it home and cleaned the MAF with cleaner really well but the problem persisted. I went ahead and changed my oil, spark plugs(gaped at .052-.054), replaced the IAC(which looked like it had been installed once before so I am guessing someone tried it and when it didn't fix the problem they returned it) and changed the fuel filter. I drove it around and it ran fine, drove it to work and it ran fine, my girlfriend took it for about 15 minutes to run an errand for me and it was fine until she got back in the parking lot and liked to never got it parked again it stalled so much.
So I went back to the drawing board and read that it is rarely the OSS that is the problem but that often times the issue is a bad coil pack. I don't have a scanner nor do I know how the heck to use one. I plan on going out of town at the end of the week and the truck has 194k miles on it so rather then take it to a shop and try to find out which COP was bad I just decided to replace all of them(I know, I know, you should never just start replacing parts). I only had time to replace 5 of them, I took the truck out and again it dove fine for an hour, went through traffic OK. It sat for an hour and when I left it started to die again, I could drop it in neutral and it would fire back up and as long as I gave it just a hair of throttle it stayed running fine, take my foot off the fuel and in a minute it would die again. After I drove for a bit it was fine again. Now I know the problem may yet be in the remaining 5 COP that I must change tonight but in case it is not I wanted to get input on this.
I've read the problem can come from a bad ground, so I took every ground point that I could find under the hood and I cleaned the connectors and took the paint off at the connection site just for good measure. The problem persists. I've read that sometimes a diode can go out on the alternator and cause this problem, I did use my amp meter and I'm checking out at 13 volts while running. I'm not the best with meters so I'm not sure how else to check the diode?
I've also read that taking it to a dealership is hit or miss for them diagnosing the problem, sometimes they find the issue, sometimes they just change the OSS. The only mechanic I trust closed his shop and is now service manager of the Dodge dealership. I'm thinking since this seems to be a common problem that maybe ford might have more knowledge of it then dodge but I trust the dodge dealership more because of who is over it. Either way I know it will sit in a dealership for awhile before it ever gets looked at and if they have to chase any electrical problems then that starts racking up $$ fast.
So what am I missing? I've thought about replacing the MAF since cleaning it the first time solved the problem. When it did this the first time I still had my 01 F250(it never gave me problems like this) and so I took the MAF off of it and swapped them and sure enough it fixed my problem so I switched them back after I cleaned the MAF and like I said it's been running fine until recently. I'd rather not throw money at this by replacing parts and hoping for the best. I've also read about tracing the harness that runs from the sensor on the pumpkin to the OSS and on. That harness runs through all kinds of stuff so I'm dreading that but it will also be a next step. I haven't pulled the OSS because its in a very awkward position on my truck.
