Ford 6.0L Power Stroke Diesel :: 2003 - Hard To Start And Runs Rough When Cold
Dec 28, 2015
My '03 6.0 is hard to start and runs rough when cold. Not just cold outside temps, but engine not up to temp. Starts and runs like a champ once it's up to temp. It was doing this when I got it, but it's getting worse.
From what I've read the common culprits are:
1 - failed solder joints on FICM power supply board
2 - bad power supply side of the FICM
3 - updated flash needed for FICM
4 - injector stiction
5 - leaky O-rings at high pressure oil rail to injectors
I have read up on how to run the voltage test on the FICM with a multimeter.
Seems like I would have to go to a dealer to have the software version for the FICM checked.
I am 100% competent to do the tests and/or repairs myself, but since I recently moved in with my fiance in a condo and my tools are in storage, I will have to do it at a friend's house. That being the case, I want to know what all of the common things are that I may need to check for so I am prepared. So, I wanted to see if there were any other common causes of this issue.
I plan to test the FICM voltage and give FICMRepair.com some business if that's the problem. And if that's not the problem (or maybe even if it is) I will get the injector seal kits and replace all of the injector seals as well as disassembling and cleaning the spool valves in the solenoids. I will also change oil and fuel filters with Motorcraft parts and Rotella synthetic oil while I'm in there.

I have an 03 F350 with the 6.0L. It has 210,000 miles on it and the injectors are beginning to be suspect. Its very hard to start when its cold, smokes and runs like crap untill it warms up.
I've found a set of injectors out of a 2005 truck with 8000 miles on them. The truck was overboosted and blew a head gasket.
Now finally to my question.....Can the overboost damage the injector? Would it be safe to buy these and install them or rebuild them before install or just leave them alone?

I'm new to diesels. I just bought a 2004 F250 with the 6.0 V8. I have the high and low circuit, contribution codes on cylinders 4 and 8. I've only had the truck for a few days but I've been reading a ton. The symptoms are hard start, rough idle/shaking, no power when cold. When it heats up and I'm over 2000 RPM it seems to be just fine. Even when hot and below 2000 RPM it does ok. I've check the FICM. It reads 48V with key on and 48V running. My plan is to do the following:
Change the Fuel Filters
Change the oil filter
Change Air Filter
Change oil with 5-W30 synth and I have both Hot Shot/Rev-X
If that doesn't work, I'll replace the two injectors. How does that sound.

2003 Excursiom 4x4 Limited
My first Diesel. Runs and drives great. Torque Pro app only showed coolant temp at 188. Would not show oil temp. Hard to cold start. New injectors. Has a programmer. He is asking 12K. It has 209K miles.
It belongs to a friend of mine and he rarely drives it. It stays under a cover most of the time.

I have a 01 7.3 crew cab dually and it's had cold start problems since i got it in 09.I have replaced everything i could think of including glow plugs gpr,harness and batteries. Any temp below 40 i have to plug it in . If i cycle it 3 or 4 times it will start but it smokes and runs ruff. My 00 7.3 excursion starts up down to about 10 degrees than i have to plug it in so i know dually is not right.
I have a afe intake,1.5 injectors, driven diesel rr, adrenilin pump,dp tune by gear head. Kinda at wits end don't mind plugging it in in dead of winter but now one night it's 30 next it's50 and i don't have to . Also have fully built trans by level 10 if it matters .I get battery light coming on every now and again. New alt about every year and a half.

My truck runs very rough and lacks power when cold, even during the Texas summer. Once it warms-up, everything is fine. It's almost like turning on a light switch. If it's plugged in for a couple/few hours, it's smooth as soon as it starts. I'm assuming it likes the oil once it reaches a specific temperature. What my problem is?

I have my 2002 Ford F250 Powerstroke. 175,000 original miles by me and only me. SCT, MBRP, Howes or Stanandyne almost always. Runs like new. It starts rough if I don't plug it in. Even on 50 degree days. Then it levels off and runs perfectly. If I plug the truck in I can drive off immediately with perfect operation of motor. I just went 1500 miles. Pulling a car hauler with car. NP at all.
New Glow Plugs, GPR "Yes it works", IPR, New Harness, Buzz Test shows it's fine, New #8 injector last year, New O rings HPOP. My buddy who is a PStroke guy said this trucks runs too perfect for it to be injectors. He recommends seals for the injectors. What does this mean. Or what else can it be. Where should I start.

I have a 2001 7.3 with 259,000 miles. It does not get too cold here, however over the past few winters when the temp is below 50 at night the first minute or two of running out of the neighborhood is tough going unless I let it heat up. It has been getting worse over the past few years and now if its even 55 or 60 I need to let it heat up. Glow plugs? Injectors?

'03 6.0 Powerstroke. Rough idle AFTER it warms up. Runs fine cold. It seems to studder and miss at mid range acceleration. Egr deleted and new oil cooler installed. New lift pump. Replaced ICP sensor. Have 48.5 volts at the FICM. Replaced the fuel pressure spring to the blue one. All new filters. Does not smoke. Does not throw codes. I need to fix this truck one last time. It has a date with the bottem of a very deep lake! It has been nothing but a pos since it hit the ripe old age of 25k miles!

I've got a cold start problem. Turn it on, wait until glow plug light goes off, hit the starter and it fires right up. It acts like it runs out of fuel and dies. Hit the starter and it fires up and dies again. Third time it stays running. It's not a long crank either. 1-2 seconds at most. Fuel pressure is 59, HPOP immediately goes 1000+, everything looks good. It will start fine the rest of the day until it sits overnight. This is an early 04.

I have an issue with my 7.3.... the truck will not start if it sits overnight without being plugged in, even in 65 degree weather. It starts and runs with a rough idle for about 10 seconds after its been plugged in for an hour, after the rough idle is gone it runs great .. it will Stat back up as long as the truck is warm (70+).... I've replaced the batteries, glow plugs, starter (it was going bad) and fuel filter. .. also replaced the gpr today. ....

My 99 250, 7.3 is having some strange issues as of lately. When I start it in the morning, when the engine has fully cooled down, it starts right up, then it throws the "wait to start light" runs real rough and just shuts off. Run the glow plugs a few times, start it up and it will do the same thing for maximum 30 minutes, then all the sudden I start it and it runs fine. I've replaced the fuel pump, cleaned the fuel bowl, new fuel filter, I just don't know where my problem could be. It doesn't make sense. But once I get it running and it warms up, runs fine all day. Go to bed, wake up, has problems again.

I'm having a bit of a cold start issue, need to know if it is normal or something is wrong. I live in southern Indiana and it's gotten down to a VERY cold 50 degrees (lol) and the past two mornings I have started it up and it seems to have a misfire first thing in the morning and it will kick into high-idle mode and after I shut it off and start it back up about 20 seconds later after the ECT gets above 100* and it runs perfectly. It has brand new 190/100 injectors from Warren, an IDP tune, and I am running 13 quarts of FoMoCo 15w-40 oil with 2 quarts of hot shot stiction eliminator (tried it before installing new injectors). And also throwing no codes. Is this normal or should I be looking for a problem?

Don't drive the truck but once a week but since its gotten colder here than usual is been harder to start when cold. Of-course I go thru the glow plug wait and then it kinda stumbles when its about to start. I do it again and most of the time is starts but seems rough for a few seconds. Once the truck is warm, no more problems starting.
I'm wondering if I have a glow plug gone bad and that cylinder is not warming up for me. Today I plugged in the block heater for maybe 2 hours and it started first time. Also, if just leave the block heater plugged in for long periods of time.. would it get to hot?? and wonder how expensive that is, most heater are costly to run. I have a timer but just wondering.

I have been debating if i should use seafoam engine treatment. My truck has been having issues with the first cold start of the day. I've noticed the rough idle that accompanies the cold start. I live in Denver so this truck sees alot of stop n go traffic. Will seafoam do anything about the dirty fuel injectors. They have to be replaced here soon but will adding seafoam solution buy me more time. If so, what are the steps on how to add. The can isn't very detailed on instructions and Internet isn't being useful. I have an 04 F250 Lariat Power Stroke 6.0L diesel

Rough idle I have had for little bit.Would stall out at idle or a stop, but fire right up? No one could figure it out with the stalling, but now its bad, started yesterday. Have white/blueish smoke sometimes, ( white smoke smells fuel) on restart after warmed when it dies, first time it took 25 mins to restart, now only takes 5 to 15 mins, when I step on it INCREDIBLE full power, fuel mileage gone to hell also since yesterday. Had full tank, now 1/2 tank.
No problems on cold start at all, no check light, 325,000 and never had this before.
Bad fuel?
ICP?
FICM?
Recent work, new turbo, ( turbo was original turbo installed when built) cooling line to waterpump, oil change, new fuel filters, front brakes and 2 new batteries.

Truck has been doing this and now getting worse. 06 f250 6.0 147,000 miles. Runs like crap when you first start and truck has trouble shifting when I first take off in the mornings until it warms up then it idles fine and runs like a champ no problem shifting. Not in a cold climate 40F at the least. Not trying to take it to the dealer and get raped. Been doing research some people say get the inductive heat flash, some say needs new injectors, some say could have a bad gasket on the injector idk. I'm trying trying to get it resolved....

My '05 Excursion recently started having rough idle and some loping when started cold. It seems to run good and idles pretty good when it warms up. I'm also getting a P0488 code (EGR Throttle Control Circuit A Range/Performance). I do have a BPD EGR and I don't recall if that would throw a code alone? I'm taking a trip next week and want to get it straightened out. Does it sound like an EGR valve issue?
I also thought about a battery issue, I know that can cause weird problems. I have Duralast batteries and they always seem to fail at about 2-3 years. I took it in and they say it tested good but I'm not always sure with them. Long story, but when cranking for longer than normal, the cranking power would drop quite a bit. Checked battery and had some corrosion. Cleaned and upon further inspection, the positive post is a bit eroded at the base and sunken in. The voltage was about 12.35 after sitting all night, a couple of the cells were reading lower than the others (about 50%, other 75%) when checked specific gravity. I tested voltage after batteries had been in the truck overnight, then unhooked from truck when testing.
I also thought about a glow plug/harness issue. The truck cranks for awhile before starting, 5-6 seconds sometimes, but not all the time. It starts up pretty quickly when warm. That's been going on for some time. Anyway, I will try to get a video of the rough start after cools down.

I'm new to owning a diesel. I have a. 2004 f250 6.0. I gotta smog the truck this weekend but the check engine light is on. Fault is P0674. I've notice during the day it starts up fine but at nights, lately it's been low 40 outside it won't start. Where to start at.

I just started having a cold start problem with my '02 Excursion this fall and I'm at my wit's end trying to fix it. Truck starts fine above about 45 degrees and when it's warm. If I plug in the block heater it also starts fine in the cold. If it's not too cold I can eventually get it started by continuing to crank it. It blows white smoke while cranking and for a few seconds after it finally turns over. Smells like fuel. Runs rough for 30 sec after starting when it finally turns over. Definitely seems like glow plugs aren't working. This truck started no problem on GPs alone without plugging in down to -20 deg F before this year.
I started by cleaning all battery connections, including the two ground posts on the engine block, I replaced one bad battery (diagnosed by Autozone; other one was OK), I checked the resistance of the glow plugs (only a few years old with about 30k miles on them) through the connectors on the GP control module (all were about 1 ohm), and confirmed 12V at the power pins in the GP control module connectors. I then replaced the GP control module and the problem is still present. Battery voltage drops from about 12.6 V before I start the GP cycle to about 12V when I turn the key to "ON" and the GP light comes on. How much should the voltage drop when the GPs are on? What the heck else could be wrong??

My truck is hard to start when cold and I suspect glow plugs. But it is not showing any codes? If it is a glow plug or glow plug relay at fault , should it throw a code?
