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.
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.
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'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.
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 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.
View 3 RepliesMy 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?
View 10 RepliesWhen it is cold out side like 20 degrees I'm having problems starting my 2000 7.3 I'm cycling it about 5 times and misses smokes white for a bit then stays running I was thinking of changing out the fuel filter. What it could be?
View 6 RepliesIt's been a while but thats because the truck has been performing well.
Current problem: The truck has been hard to start this year as if the glow plugs are not working or are bad. It will start right up if I use the block heater.
Just recently, I also noticed that the EBPV is not coming on when warming up the truck.
Also, This winter season, the engine temp is not coming up to normal. the engine temp needle is more on the low side towards the C and definitely less than 1/2 way up where is normally is. When driving on the highway, the temp comes up more. but sitting at idle it barely gets warm.
So not sure if all 3 are related or not, but looking for a starting point.
20 degrees out this morning truck not plugged in, didn't want to start had to cycle 4-5 times, each time waiting for glow plug Light to go out.
Finally cranked didn't sound pretty but cranked. Once it started idling on its own got out and seen a puddle of oil under the front of the engine drivers side center kind of.
Got up on the truck and shined a light in the valley and seen a puddle in intake valley. Heres my question? Where did this oil come from? Once it warmed up it quit and oil kinda disappeared from valley???
I had turbo off a few months ago because I thought I had a bearing down in it, but found some bolts lose. When I put turbo back on I broke the wire plug on front of the pedestal so I just left it unplugged. Very hard to cold start now that that is unhooked.
Did leaving this unhooked create a hard cold start? Should I put another pedestal on it with the plug or install one without it? Also will it hurt to leave plugged in overnight?
2003 F350 7.3L 164k miles. Got towed in with hard to start cold complaint.
Hooked it up to the Snap On Verus Pro scan tool and we get up to 3000 psi on the ICP cranking, IPR value seems within spec, we have rpms over 100 on tool, pulse width within spec, computer voltage above 10v while cranking, verified output of glow plug module (California) and glow plugs get voltage for approx 50 seconds @ 80 degrees farenheit, glow plugs all read 0 ohms resistance.
injectors do NOT sound the same during buzz test.
Vehicle takes EXCESSIVE cranking cold to eventually get it started. LOTS of cranking. Just had to replace starter and a battery because driver burned em out. It feels like the vehicle shakes when it gets running. Black smoke when revving cold. Sometimes white smoke while cranking.
Once the engine has been warmed up, it starts perfectly every time.
I have spent two days in the engine bay looking for chaffed wires and doing diag and my current diagnosis is bad injectors. I feel there COULD also be high pressure oil leak, or a mechanical issue such as low compression. No compression guage yet for this truck. We have the ICP and IPR fittings to do a shop air test. Recently did a 6.0L and went thru everything and eventually diagnosed it as bad HPOP. LOW ICP pressure.
I noticed two of the cylinders were at maybe 8% Perdel on the data. Seems too high. Also, it "passed" the KOER self test and "passed" the injector buzz test with no codes after, but the audible sound of injectors didn't "seem" right to me, but I am new to these engines.
My 1999 F550 7.3L has been hard to start when it's cold outside since I got it with about 150k on it (it has 200k on it now). Last year we tested the glow plugs and sure enough 5 of 8 were bad. So they are all new now. It worked a little with the hard start, but not much.
When it's cold out the engine will crank forever amongst clouds of smoke and the smell of unburnt diesel fuel and sometimes eventually start, followed by smoke and sputtering until the cylinders clear out. However, what I have noticed recently is that it will sometimes start in the first few revolutions. It seems like the best way to start cold is as follows:
1. Let the glow plugs heat up for a minute or two,
2. Crank engine for 10 or 15 seconds and stop,
3. Crank engine again, but stop if it doesn't catch in the first couple of revolutions,
4. Repeat step 3 until engine starts.
When it starts using this method, it's immediate and it's running smoothly immediately with minimal smoke. This is making me think there's a computer or sensor issue, but I have no codes.
I have a 2002 f350 that has had cold starting issues since I bought it. I have replaced the glow plugs twice, the glow plug solenoid four times. When I put a new solenoid on it it works fine for a short time. I know the solenoids are bad because I get battery voltage on one side and nothing on the other. If I jump the solenoid with a jumper wire I can get the truck to start. I thought I was getting bad solenoids but I have recently tested the activation circuit and am getting constant power there. I.e. It never shuts off. I think this is what is causing the solenoids to burn up. From the tracing of wiring diagrams I have done, the only thing before the solenoid is the Pcm. So now to the question,
1) What controls the activation of the Glow plugs? Is there a temperature sensor or something before the Pcm.
2) Is this a case of my Pcm going out on me? I am a mechanic in the army so I have a decent understanding of mechanics.
However I am at a loss for these systems.
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.
2002 Excursion, 7.3L 375,xxx miles ... As the weather is cooling off, my excursion has a starting problem for a few years.
Replaced all the glow plugs last year. We (my brothers and I) thought it was injectors, but in the summer time or if block heater is plugged in, she starts normally and idles smoothly. And no smoke and runs fine once she warms up.
When cold, it acts like 1 or 2 injectors are not firing. Have run all kinds of cleaners through the oil and fuel.....
Don't want to swap injectors just to swap parts. Would like to diagnose problem....
Truck is a completely stock 2002. New injector o-rings, glow plugs, valve cover harness, and injector cups a year ago... all motorcraft parts. New batteries and starter in the last 6 months.
I've checked the GPR both at the relay and harness got power all the way to the valve cover harness on all 8. Injector buzz test sounds okay as well.
Had a stuck IPR issue a few moths ago that caused a CEL and died while running. Took apart and cleaned the IPR and CEL is gone truck runs great once started and has correct IPR pressures in all RPM ranges.
Truck runs great once it is started and is not sluggish until warm like when it was hard to start when cold with leaking injector o-rings.
Truck has performed flawlessly during that time period. Early build 2003 CC SB 4wd King Ranch truck 94,000 miles I purchased new in 2003. Good batteries. Bone stock except for superchips tune.
First sign of trouble: Two weeks ago CEL came on, P2285 Injector Control Pressure Circuit Low, as soon as truck was started after sitting unused for about a month. Bought new sensor, haven't installed it yet (early model sensor located under turbo on rear of engine and a real pain to change). Truck still started fine and ran fine. Dreading the ICP sensor install, I continued to drive the truck. Drove truck 5 miles to get tractor fuel. Got fuel, started truck and drove away. Got 200ft and truck died. I changed secondary filter under hood, turned key on and let pump cycle about 4 times. Truck started. Cleared codes. No longer have CEL. Drove 5 miles home, shut truck off and no start.
Troubleshooting: Changed primary filter under truck. Really cruddy (probably 80,000 mi on it). I cleaned inside filter housing thoroughly. I had to cycle pump KOEO about 6 times before it started. Shut off and immediately tried to start. No start. Ran pump KOEO about 30 seconds. Started. Shut off and same result. I then drove truck 4 miles driving both normal and WOT. No problems, no smoke, no CEL, ran perfectly normal. Shut off, no start until cycling pump KOEO for about 30 seconds. No codes set.
I then removed cap from secondary filter and checked for trash. Fuel and bowl were clean. I did notice fuel drained completely from bowl in about 5 minutes. I reinstalled filter and put pressure gauge on housing.
Fuel pressure readings: KOEO 55psi after about 3 seconds. Engine running 55psi. Turn key off and pressure instantly drops to 25psi, then bleeds off to zero over about a 3 minute time period. Does this seem normal?
Questions: Could the clogged fuel filters cause the p2285 code to set? Could the HPOP system have developed a leak and cause these symptoms?
Could an injector leak cause these symptoms and engine still run ok?
Action Plan: Install new ICP sensor. Do bubble test to check for injector compression leak. Install Blue Spring mod. Waiting on parts. Possibly buy scanner which will read HPOP output etc. Any recommendations here?
This is an issue I started chasing after having all the injectors replaced on my aunt's F-350. We had them replaced due to hard/no start on cold (dealership told her they needed to be changed). Unfortunately, I did not get the buzz test results before changing the injectors.
So far that has been replaced:
Injectors
ICP (was leaking)
IPR
both UVCH
IDM (twice)
The issue we are having right now is that only 2 injectors (#6, #7) buzz properly. Initially when we changed the injectors, it did start but didn't seem to run quite right. We did the buzz test and at that time and injectors 1,3,5,6,7 would buzz strong but the rest were weak. After some forum lurking, we suspected that the IDM was faulty. We purchased a refurbished one and after we changed it, only injectors 6,7 would buzz strong. Thinking a faulty IDM was sent it back for a replacement. While waiting, we decided to put the old one back in figuring it would go back as it was before but only 6,7 would buzz strong. We receive the second IDM and same thing, only 6,7 buzz strong. We did a continuity test from the IDM connector and they all get 2.7 ohms (it was an older multimeter so not sure if being .1 under the 2.8-3.6 range is bad).
What I did next is use the uvch external pigtail to test the injectors. I plugged the extra pig tail into the uvch and then the ends of the wires into the plug of the upper harness. Afterwards, I would swap a different injector wire (on the pigtail) to the #6 injector wire (on the upper harness). Whatever injector that would go to #6 would fire correctly. So I know that the injectors themselves are fine. I am suspecting the wiring harnesses (upper/lower) but the continuity test would say otherwise. We also do not get any fault codes except for the EBP occasionally (waiting for a new one). I am lost on what to test or look at next.
I recently bought an 03 F350. I've noticed on cold starts that it has no power. After about 5 minutes it runs very well. I have not noticed any misfires or smoke and there are no codes thrown. Based on what I have read here, I assumed it was a FICM issue. I just got done testing it and it was at a solid 48v with 1 dip to 46 on engine crank. I'm baffled at this point. The truck literally has no other issues except low power for the first 5 minutes.
View 14 RepliesI have had my truck for about 4 years bought it used. I've replaced the motor due to #1 cylinder blowing up. So after I replaced the motor, it wouldn't start. Replaced O rings on HPOP (High Pressure Oil Pump) and started. When moving back to Colorado where I am stationed. It started getting harder and harder to start.
Then it got to the point where it wouldn't start so I would have to wait until I could start it or use a shot of starting fluid and yes I hate that. But I don't have a choice. I've bought new O rings replaced them and my IPR with upgraded screen. It fixed it for a week then the hard start came back. Tried unplugging ICP Sensor still hard start problem. ICP was reading 85%. When the truck is cold it fires right up no problems till it gets hot! Then driving down the high and hitting an off ramp it will shut off. When I try revers it will also shut off. The truck only has 111,252 miles.
03 6.0 with 90k miles. New heads, all orings , stand pipes, injectors , glow plugs, egr delete , oil cooler and studs . Has sct livewire. Just took the truck to the shop for a hard start issue and misfiring at around 30% throttle driving. It would fire up great in the mornings with some white/blue smoke till warm. But after it was warmed up you shut it off it would fire right back up but very slow to reach proper idle.
But if it set for about an hour it would crank great start but same lazy idle up but now it wouldn't get over 300 rpm before it would die. And do this for 5 or so more times before finally idling up. Then runs pretty good other than the misfire. So he said it's either the hpop ipr or icp. I had him replace all 3 with motorcraft parts. Still the same issue ! Return the truck to stock tune and it doesn't have any power . My pockets are only so deep...
