2003 F250 crew cab 6.0 ... Where are the main problem areas on the ficm wiring harness truck will start and run great at times and at times it just start and misfire lope jump and buck it has to be a short I've changed the icp and crank / cam sensors some days it runs fine had issue with alternator replaced it.
View 10 Replies1st to 2nd fine 2nd to 3rd it jumps a few times like it cant find the gear and you will see it on the video. I am confused what it could be. the truck received a new solenoid last year from ford because the tow haul light was flashing and now i have this issue. I believe it is also the reason the truck is running much slower down the 1/4.....

Just did an egr delete, oil cooler, icp sensor and exhaust on an 03 f250 6.0l. got it all back together and it cranked up and ran for about 30 seconds then stumbled and died. read to pull out the ipr sensor and check it and it had a piece of debris on it covering the screen. took of the debris and still no start.
View 6 RepliesI have a 2003 F-250. For 8 months now we have been trying to get my truck to start. We have replaced the High pressure oil pump, Oil cooler, PCM, Main wiring harness, FICM, Injectors,, ICP, and IPR. Still we are not getting enough pressure to start the truck. What is happening is the pressure will get to about 340 and will not increase from there. If we are to disconnect of one the connectors from the FICM the pressure will reach 640. Now we are able to get the truck started with ether, but will not remain started. As of right now we are still trying to figure out what is causing this problem?
View 14 RepliesI drove my 03 f-250 to work Monday everything was good no issues. At end of my shift truck will not start . turn key dash lights up glow plugs cycle turn to start nothing . Does not turn over. after some checking batteries are good. Starter will crank if i manually engage it but truck will not run even with jumping starter with ignition turned on . hooked scanner up says cannot communicate. Checked fuses etc fuse #31 has no power to it (trans range selector and starter relay)question is where to look next?
View 9 RepliesI have a 03 f250 6.0 had it for 2 years never had a problem. Last week I went out and started it to warm it's up as it is cold out here and it started fine I then noticed some thing hanging down under the dash so I started tucking it up under there and it arced and all gauges shut off and the truck shut off. So I took the panel down and it was the biometric pressure sensor that was hanging and the previous owner had a remote start on there that I never knew about and 2 wires on the sensor were stripped and not taped as well as some others. I checked all fuses and relays all working good tested fuse box and everything good there, replaced bio sensor and still nothing turn the key and try to start it and it does nothing injectors, don't precycle fuel pump doesn't run and starter doesn't kick in. I jumped starter off the wire on fender and it turns over but still doesn't start. Also I think it's the ecu but don't want to buy another one if I'm not sure if that's the problem.
View 7 RepliesI have an early 03 F250 6.0 that won't start after I replaced all 3 FICM connectors, also # 8 injector pin and connector. It has been almost impossible to start before the repair.
I checked the grounds on
Pins #1 2 3 22 they were all .5 ohms
Pin #32 was 1.0 ohms.
Pins #7 27 were 12.7v ( battery voltage)
I have double checked all pin connections and wire colors, they are in the right holes, I haven't done any cranking voltage tests, as I am alone. The FICM has 48.2 v.
I am trying to diagnose an issue with my 2003 F-250 6.0L PSD.
The first time I crank it everyday, it struggles to start. Beyond that, it seems to run fine and not have issues cranking throughout the day.
I've recently replaced both batteries, the FICM, the fuel filters and the FI wiring harness. What could be the issue?
The video shows exactly what I deal with every morning.
YouTube - 2003 F-250 Cold Start Issue ....
My 2003 f250 6.0l just up and quit. It make a popping noise out of the intake when cranking. I am getting 1150 psi at the icp and ipr is at 62% which seems high to me. The FICM voltage seem fine unless the batteries are drained and I am getting FICM sync. I replaced the HPOP, ICP sensor and IPR about a year ago. I recently replaced the air conditioning compressor and power steering pump. I am at a bit of a loss. I did pull the IPR and everything looked fine.
View 14 RepliesI have an 03 super duty with the 6.0, came back from vacation with my 5th wheel in tow. Lost the upper turbo hose twice on way home. Managed to get it rigged and made it home and parked it. a week later went to uncouple and move the truck and had some very strange issues. Started fine but could barely make it up driveway (no trailer at this point). No power, felt like when turbo hose came off. Got it moved and checked turbo hose and all was good?? Went out a couple days later and no start.
Checked all relative fuses and relays and all checked good. Jumped starter solenoid and starter worked fine. turned key on and jumped quick connect on right side of engine compartment to battery and it fired right up and ran. Jiggled shifter around in park and neutral and nothing. BTW I always here the relay clicking and swapped with one of the others just to be sure, same thing. After looking on the internet for a day and a half thought maybe a NSS in the tranny but I think I have the 5R110 that does not apply??
I've got an issue with my truck, I was towing home my camper this weekend and my engine started missing out and vibrating very bad, then it overheated... pulled over and check codes, p0263, p0299, p0300, p0301. Oil all over engine, tons of blow by, definitely a dead miss on cylinder 1. Smokes bad out of exhaust, zero power, and blows cap off of oil filler when loose, tons of smoke and oil from ccv.
My question is, could it be in the valve train? Or is it going to lie in the piston/rings? Blown head gasket? It did overheat, but didn't puke out of bottle, turbo timer kept it running for a bit after I shut it down roadside, egts were definitely high. Also the egr is deleted, have a predator programmer with custom tune for she delete.
I replaced the speed sensor in the differential yesterday, but it didn't make a lick of difference. I've been having intermittent problems with the speedo ever since I bought the truck. When the speedo starts acting up, the truck will sometimes momentarily cut out and buck a couple of times. It was first mentioned this post, post # 35. I had the truck in the shop for a new oil cooler, EGR delete, standpipes, dummy plugs and STC fittings, and when I got it back it ran worse than before as detailed here in post #1. It turned out I had a torn IPR screen.
I replaced that and it cleared up all of the problems I had except for the speedo problem I originally had. The truck actually ran perfectly on the way home from work yesterday, about 20 miles. No speedo problems and no cutting out. This is not unusual, as the problem is only intermittent. I put the new VSS in last night but did not drive it until this morning. This morning, same thing again, speedo swinging crazily. When cruising about 70 it the speedo would suddenly jump up to about 90 and that is when the truck would cut out and buck a couple of time. The VSS is a Dorman product and proudly displays "MADE IN CHINA".
Should I try a better quality sensor? Rock Auto sells an Airtex/Wells sensor that seems to be of good quality, but I can't determine where it was manufactured. The only reason I bought the Dorman is because I could get it next day from Amazon. Should I be looking at another source for the problem? This is very discouraging because this one thing is what is keeping the truck from being mechanically sound, and I'm trying to get it ready to tow an RV this summer.
Truck has not been bullet proofed and has aftermarket air intake. Truck has 185km on it (purchased at 160km a year ago). For the Ham Radio guys out there, this is the most electrically noisy vehicle I've owned with S9+ noise while accelerating and S7 going down the highway ...
The faults show up as:edit Can be hard to start cold, takes couple of tries if it's been sitting for a bit (week or more)
No power when cold, that is a lot of pedal results in little power
Misses a lot when cold
Light blue smoke when missing when cold
When fully warmed up which takes 15 minutes of idling regardless the time of year:under load (heavy acceleration while loaded or not, or just in towing, or carrying) it misses a few times a minute, otherwise runs well
It feels like it just doesn't fire a cylinder if it were a gasser, or as if the spark plug weren't connected, but it's not a constant miss, it is intermittent. No load means hardly any misses. Load means lots of misses even running down the road. Should be pulling hard up a hill where it misses lots more.
What I've looked at :
FICM voltage 47.8 standing, 47.6 cranking and running.
FICM is aftermarket and there are no cold solder joints.
Added Archoil 9100 with no change
Wires to FICM are tight and connectors aren't cracked
edit Wires to Injectors are tight and connectors aren't cracked
Exhaust temps range between 500F and 800F during any of these events
Basic ODB reader shows no codes
I'm looking for a couple of things - I'm not much of a mechanic so this has to go to a shop for diagnosis and repairs. Before I run it someplace, what sort of diagnostic tools should that shop be equipped with to find out what's going on? Also, given what you know of the problem, am I likely to damage things if I continue towing activities?
So my buddy was driving my truck and boat through Amarillo and suddeny had a buck/surge accompanied with black smoke. I left my torque app with him. Its throwing codes: P2287,2285, and P????(fault log got erased and I'm going from memory) concerning #8 cyl. I got there today and we noticed coolant leak on left side. Its small and I cant tell the source, but it is wetting the exhaust manifold on left side. Also now its blowing white, black, grey smoke. At idle its more white/ grey. Under load it mixes a little blck in. I only had time to check the ICP on torque and at idle its bouncing from 0.9 to 1.1. Unplugged ICP ran about the same. Still started and idled fine with white smoke. No oil in ICP or connector.
So I'm no expert but I think ive got a bad icp and something else going on. I didn't pull the egr valve and look so no idea on the cooler ,yup syill have the cooler. Degas has a small amount of white residue directly under the cap but no puking. Degas is just below the max line (on the sticker).
One other note only code originally was the 2287 last night. Now this am there was the other codes ref'd above.
I've seen the gods of the diesel engine do some amazing things on these forums, so after a year of pulling my hair out, I've signed up to try this myself.
This time least year,I bought a 2004.5 6.0L F-250 with 196k on it to haul around the state for my new business. At this time, I knew nothing about diesel engines AT ALL WHATSOEVER, but I've never been afraid to tackle anything and mechanics are not totally foreign to me. Not to mention, I was hoping everything might just go peach-ily for at least a couple years. (for what it's worth, My dad and his family are mostly shade tree mechanics and I'm a power plant operator so mechanical concepts are not totally foreign to me, just never had a diesel before)
To begin, I purchased the truck and everything was fine for about 2 weeks. Then abruptly one morning I noticed a couple of hefty surges on the way to work. Then, on the way home I thought all was well until about half way home, it did it again! as I was pulling up, it galloped once I pulled my foot off the pedal. like ba-DA-DA-DA-da-da-da-da-da-da-DA-DA-DA-DA-DA-da-da-__ and then STALL! Shaking with concern over potentially an awful purchase, I turned the truck back on only to find... that it's fine?!?? No problems for the next two days and then it happened again. then good for a week, then again. then good for 2 weeks, then again. so then I bought auto enginuity and an edge insight to do some troubleshooting. Let that sink in as I explain it's history a bit.
-All but one injector is ford remanufactured the other is stock (was never told which one)
-replaced head gasket with another OEM
-ARP Head Studs
-EGR delete
-HPOP AND STC fitting both replaced
-FICM replaced
-Oil cooler replaced 50k ago
-ICP and pig tail replaced right before my purchase
- Has been through roughly a handful of ICP's since I've had it (I'll explain)
-I've cleaned the EBP tube a lot and updated it to the newer ford sensor with the flare fitting
-I use Rotella T6 5W40 and CAT ELC-1 Coolant.
-Deltas are under 10 at normal driving
-I typically drive under 2200 rpm until warm then like a banshee at operating temps.
Now one year later, its not fixed, but I feel like I'm close.
The DTC's I have seen are ICP sensor circuit intermittent (I think po2884) and Power Blance contribution failure from cylinders #2 #7 and #8 but never at the same time.
Every time I replace the ICP, it will be problem free for about 6 weeks and then it will return full force (surging and galloping when warm about 50% of the time)
During a possession I see the following:
*Cylinder power contribution test yields no issues at idle or when cold. when "possessed", the whole baseline across all cylinders goes up and all cylinders dip and return at random. none singled out
*ICP voltage fluctuating from ~.6v to 1v (.24 @koeo) *Also during a surge*
*ICP PSI dancing up and down ~600 to 900psi (0.0 @koeo and ~500 at normal warm idle) *Also during a surge*
*IPR% bumps up and down ~25% to 30% (15%@ koeo and 23% at normal warm idle) *Also during a surge*
*FICM Voltage anywhere between 47.5v and 49v
*EBP is normally 15-20 psi
*Boost is 1-7 normal and is not affected by "possession"
These numbers have taken a long time to get since it will only be possessed for about 3-10 seconds at a time and then will disappear for days. The stall has only happened about 5 total times in a year. The surging is much more frequent. I usually get a buck or 2 on any given trip that is longer than a half hour but NOT IMMEDIATELY AFTER AN ICP REPLACEMENT.
On one occasion, I noticed that the ICP PSI actually tanked to about 350 right before the IPR went from 25% to 40% right before a posession. I was driving about 35mph through town at the time.
Here's my thoughts...
- Did that one occasion clue me in to an intermittent HPO system leak causing the truck to briefly over-compensate by spiking the IPR?
- Is my ICP pig tail jobby done incorrectly? If there was a short, wouldn't I see the volts drop to 0? I have another one and will replace to rule it out.
- I have yet to test my fuel pressure, but I figured if it was low, I would have lost injectors by now. (I replace filters probably too often but next empty tank, I'm dropping it and checking the screen and strainers)
I should also mention that I have buzz tested the injectors and I can hear each one clear as day, and that for REALLY long trips, it actually returns to normal. In other words, my window of death is between 30min and 2hrs of driving; invincible after.
I have a 2003 f 350 6.0, when under a heavy laod such as towing a 3000-pound trailer up a long hill at approx 60mph and 2000 rpm it intermittently mis fires.The boost gauge bounces up and down and i here a poping sound from the engine compartment.I have had it to several dealer and independent shops but with out the trailer or a heavy load it runs perfectly.They have told me fuel pressure is good and changed all fuel filters with OEM parts.
View 3 RepliesI've got a99 F2 50 super duty with a 2000 2001 motor. I got the truck in the beginning of last winter so this is my first summer with it.
When I first got the truck there are injector issues with the truck. Since I fix the issues there has been little problems out of the truck however it's still suffered misfires when Cold but once up to operating temperature it was fine. Yesterday I had to go with a friend before leaving for the trip I checked the oil it was full and appeared normal the trip was about 150 miles. I came home park the truck after everything was done. This morning I came out started the truck everything acted as it should... truck fired right up everything was great went and dropped off my trailer at the yard come back got fuel when I come back out from paying for the fuel the truck took about 30 seconds to fire up I checked my gauges and torque pro and everything seemed normal. So on my way I went.
I drove about 10 miles on the highway to the place I had to be when I got done doing my business I came back out to start my truck and it did the same thing this time however it took longer to start I managed to drive about a mile down the road when I noticed my old pressure gauge flickering and my Oil pressure light on I immediately shut it down and coasted into O'Reilly's parking lot I check the oil in the truck and it was empty according to the stick I added two whole gallon.... With it filled back up down the road I went. So currently the truck is still suffering from a long hard starts it takes 30 to 45 seconds before it all actually fire up once it fires up everything appears to be fine however the truck is slowly smoking a bluish black color... It's never done this before however I've never had this truck in the middle of summer when it's real hot out I don't think this is normal.
The truck doesn't appear to be down on any power actually it, acts as if it might've picked up of some power it is felt real peppy today compared to other days. Also I might note that about a week or two ago I started smelling diesel like either really rich diesel or raw diesel wasn't too bad but I just got whiffs of it for now and then. Now there is a burn oil smell present from the exhaust. Like I was saying earlier when I first got the truck I had to service the injector O-rings... I was told that the miss firing when cold was caused by the Poppitz sticking. The misfire hasn't been present since it got a little warm outside like I was saying it was only when the vehicle is cold.... Just thought I would mention the injector issue not sure if it's relative or not..... My thoughts are it's back to an injector issue or O-rings or possibly did I wipe the motor when it ran out of oil. I am not aware of where the oil went as there is been no leaks or drips.
I'm normally in the 7.3 forum, but a friend has a 2003 6.0 with a P2285. I get the impression that on the 03 and early 04 models, this code is nearly always a failed ICP sensor or the wiring leading to it. It also has a cylinder 5 misfire code, but I suspect that's a separate issue. I had the truck hooked up and the ICP held pretty much steady at 870 psi. I didn't look at ICP voltage, but I'm willing to bet it was probably 0v and the pressure reading was inferred and not actual.
Will a failed ICP sensor also cause the truck to have decreased power? Any tips to make the sensor easier to change, like a certain socket/ratchet combination or anything? Is it easier from the top, or bottom? I do have a lift . . .
I have an 04 6.0. My truck was running perfect, no problems. I start my truck, it started idealing rough for a couple seconds then just died. After that it just kept cranking and no start. There are no codes, tried unplugging the ICP sensor and nothing. Checked the fuel filter and its filling up with fuel before cranking. Oil is at a good level. FICM is reading 46.5-47.5 before cranking. Checked the ICP Psi I'm only building 11psi and HPOP was replaced in October.
View 13 RepliesMy husband and I purchased a 2004 f250 king ranch 6.0L... We love the truck, despite the headaches. We took it to a dealership and spent just under $5k in parts, drove it for a month (everything going great) until we shut it off to bs w a friend and it won't turn back on. It's been sitting for 4 days and nothing. Cranks and cranks, but won't actually start. We are pretty handy with gas trucks, but this diesel is out of our element- we are getting better though haha!
We looked on here and saw that the no start could be bc of the FICM - swapped it out- not the issue.
Now the codes being thrown are P2291 & P2285 (or so my husband says)
We are thinking if we replace the ICP and that fixes it, we won't need to do the HPOP. Or do we need to do it as well? Are we on the right track?
When we shut it off, it didn't have any lights on, no gauge fluctuations, or any "red flags". This is why we are stumped!!
(Ford dealership fixes: 2 batteries, new starter, new tank cap, new oil cooler, maybe a few others- receipts not infront of me).
Like I mentioned, we've already dropped more money than we have into this truck and now it's taking more- we love the truck and once it's fixed we will "have a new truck" it just sucks bc my husband works afternoons and I'm a stay at home mom with a 14mo and this is our only vehicle.
I have an 05 f250 with 109k. Recently I turned off my truck, waited about 45 min or so and upon returning the truck would just crank and crank with no fire. After waiting about 4hrs the truck started right up like nothing was wrong.
Yesterday it did it to me again. This time I have it a small shot of starting fluid and it fired right up and ran like a champ all the way to the shop..... I got the call today from the mechanic saying I have 5 injectors that are bad, 2 glow plugs and harnesses. His quote was 2400 out the door.
