View 1 RepliesAbout a year or so ago, cyl 5 glow plug failed. 6 months later number 1 failed. Now number 3. I seem to remember someone mentioning that the module can sometimes cause produce similar problems. Are there two circuits in the module, one for the left and one for the right, or just one circuit for both? 167K on it so it doesn't surprise me that they fail but just odd that they are all on the same side.
View 5 RepliesI drained my batteries enough that I needed a jump after the last time I was troubleshooting trailer wiring, since I keyed on a bunch of times. What fuse or relay do I need to pull out next time? I'm thinking of pulling fuse 302, HFCM relay (or fuse 7 in the disto box under hood) to disable the fuel pump, but what fuse or relay is for the glow plugs?
View 2 RepliesI'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 RepliesI've recently gone through and replaced all 8 of my '06 6.0's glow plugs as the check engine light has successively come on (I first did #3 about a year ago, then #5 seven months ago, #1 and #7 two months ago, and #2, #4, #6, #8 about two weeks, did all 4 on the drive side even the code was only for #6). A light came up for #1 again today, so I'm wondering would this be symptoms of failed glow plug control module? Also, can a failed module cause the glow plugs to fail prematurely? Haven't had a chance to ohm the plug yet.
The truck has also has been hard to start when cold and had a pretty bad engine flutter the past 8 months when cold at medium range rpms in the upper gears (1500-2000 rpms in 3rd, 4th, and 5th gear and accelerating like a grandma). I don't know if it could be glow plug related, or a bigger issue (I did the EGR/Oil cooler myself about a year ago as well and things ran good until the winter hit). If I plugged the truck in over night over the winter, the flutter was not nearly as bad, but now it's summer and it's still not liking the cold take offs.
I replaced the glow plugs and gpr and the truck won't start. I'm also having to replace the water fuel separator. What is going on? 1999 F250 7.3l ....
View 10 RepliesI "Bulletproofed" my f-250 Super-duty last summer and she ran great for a time, actually she is still running great, except for one thing that is driving me crazy. On a cold start it turns over until the oil pressure builds up. Then she will crank and runs fine, also starts normally after warm, turns over a couple of times and cranks.
I have oil in the filter housing, have replaced the seal at the bottom of it. Just pulled the oil rails off and replaced the seals on them, and a new IPR seal and filter. I am still having the problem, F.I.C.M. voltage has been fluctuating between 45 and 46 vdc. I have a P300 and P308 code.
I haven't really considered Injectors because it is idling smooth as silk and has great power.
Could a leaking passenger side glow plug harness cause a "hot no start?
View 5 RepliesI am having a difficult time trying to track down the root cause of a P1393 code in a 99.5 7.3. The code means all the glow plugs on the driver's side are not working. I don't have any other codes related to the glow plug system present in my computer.
I've replaced:
1)The Glow Plug Relay (I have the CA version with the shunt)
2)Valve cover gaskets and wire harnesses
3)Glow plugs
I've used all OEM product replacements.
Additional testing:
1)Voltage on the glow plug relay posts going to the left and right bank is the same (I think this means the shunt is okay)
2)Disconnecting the wire harness to the valve covers yields 12 volts at all 8 glow plug connections during the glow plug cycle
3)In one of the steps of a troubleshooting document I found, it requires a KOEO On-Demand Self Test. It does not complete and ends with a P0605 code, "Internal CTRL Module ROM Error" using a Snap On Scan tool.
4)Using the Snap On scan tool to run a glow plug test results in "Test has aborted 64 - Abnormal Exit without result".
5)I checked part of the wiring loom and it seemed to be good.
Is there a way to test the wire that goes from the Glow Plug Relay on the driver-side bank to the PCM? I think that either this wire is bad, or a bad PCM.
6.0 has had dummy plugs and stand pipes replaced and still has a long crank when cold. The kicker is that it doesn't happen when the truck is parked nose up in the driveway. It only happens if the truck is level or back into the driveway. I suspect it's that the HPOP is losing prime from somewhere.
View 6 RepliesThe past couple of cold starts (not real cold mornings though) I have experienced long crank time to start. Once started she starts normally. No time to read but I'm getting a little worried that I'll get stuck somewhere. I'll check back with my phone when I get into an area with cel service.
View 14 RepliesI have a 07 f250 6.0l and it has 112k on it, I've owned it for over 4yrs, since 45k, and no issues, but this morning I went out to start my truck didn't start, tried again and started, but the glow plug controller made a funny buzzing noise, (making that noise for a few weeks), so I went to ford and bought a new controller, so I hope that fixed that, but on my way to work I was at a traffic light and noticed that my ficmv were between 46-48.5, icp 23-24%, vgt around 68%, truck was at temp, should I start to worry about the ficm??, I have to replace my ground on driver side battery, noticed that it is corroding, gonna do that, I have 2 yellow top optima batteries about 3 yrs old....
View 9 RepliesMy 2007 has been having this issue for the last couple of years and has gotten pretty consistent lately. When it's below about 60 and the engine has cooled to ambient temps, it will crank all day and not start. Once ambient temps are about 60, it will fire up and runs like a champ. You'd never know it had an issue. It's got a #4 glow plug fault. Other than that, everything is reading within parameters. FICM, GPCM, or what?
View 5 RepliesI have a early 99 f250 super duty 7.3l and it's giving me fits. about a month ago the truck started to do a hot no start. drove truck for about a hour. Shut it off and half hour later no start. Let it sit over night and would start with long crank.
Changed CPS no change. Pulled tuner and set back to stock. No change.
Changed fuel filter, no change.
After reading forums changed IPR and truck started and ran great. About a week ago back to the same problem. Battery's are about 2 months old. Oil change and oil filter a month ago.
Checked the hpop reservoir and its 1/2 from the top.
Checked fuel bowl and it has fuel. no sign of oil in it.
Drained bowl and watch bowl fill back up. seems to fill quickly.
Pulled passside valve cover to check for bad orings while cranking.
Every thing seems fine. have not done driver side yet. used FORSCAN and ran buzzed test on injectors and they all buzzed what seems to be about the same. ran test couple of times to make sure. this morning I ran a live scan while cranking and this is what I got right before it started. ICP 660.6psi, IPR 64.84% and RPMs 227. took 8.86 seconds to start. after work scaned again for hot no start and this what I got. ICP 292.9psi, IPR 55.86%. and RPMS 203. unplug ICP and no change. still will not start. one thing I did notice when plugging ICP back in I looked down in side at the pins and can see what seems to be bubbling around one of the pins. the pig tail has just the slights sign of oil.
Had long start issues. Would turn over for 5 seconds - shut off- turn over for 5 seconds - shut off - third try on 4-5 seconds the low oil pressure would come up and HOP would fire injectors and start up.
Was not sure what was up, so look it to Ford. They did leak down test and found seal at the top of injector 4 was leaking. Replaced it and leak moved to other injector. Basically moving to the next weakest seal point. I told them to stop as i did not want to pay, parts, labour and shop time to replace all injectors, etc. They also said power across all injectors was good, but 3 & 7 were not contributing on cold start.
I drove it home and bought parts. New cups and seal for all 8 on fuel rail. New gasket kits for injectors. Plus 2 new injectors to replace 3 and 7.
Replaced injectors in 3 & 7 with the 2 remanufactured i bought. Replaced all cups and seals on fuel rails. So it has new injectors in 3, 4 & 7.
As for the other injectors i took the 5 of them right apart and cleaned them and re-assembled. Took about an hour per injector, took my time to get it right, just FYI. Went pretty good i thought. Seemed pretty straight forward actually.
Now no start - no high oil pressure at all. LOP comes up right away. Scanner shows no HOP no matter how long i crank it.
FICM power good, 47.5 - 48
shows FICM sync - YES
IPR sits at 14% and jumps to 84% on crank - starting, see photos below.
Scanner prior to crank
Scan during crank
Note zero IPC - PSI
Right now.... Got the valve cover off on passenger side. Cannot see oil squirting out the sides of any injectors, but line of sight is limited. Maybe need a small mirror to see in there. LOP comes up better than it has in years, but no HOP now. Before rebuild it seemed i had good HOP but low LOP.
I drove it home from Ford and into my garage, so i do not believe the HPOP crapped out sitting in the garage, so i am ruling that out as a fail, at this time.
Dummy plugs were replaced 5 years ago and o-rings looked decent.
Pulled the small plug screw at the top of the fuel rail. Cranked it until oil came out, bleeding air. then replaced the screw plug. Have not done that on drivers sideyet. Will try that tomorrow. However, think this is more than an air issue, as i have cranked it over plenty, unless i just have that much air.
Going to pull the valve cover on the Driver's side tomorrow. Then will have both covers off at same time to view all.
Noted that if i put compressed air into the screw hole on top of the fuel rail, i can hear air coming out from below the fuel rail. Nothing at the base or around injectors. Does not seem to be at the cups either.
Just wondering.... Buy applying air to those screw plug holes, is that the same as doing the air test at the sensor that pokes up through the valve cover.
With air pressure at these scew plugs on the fuel rail, should this be sealed and be air tight and hear no air leakage. Because it was not air tight on the drivers side before i closed that side up. I am curious about this.
I am assuming i still have a HOP leak. I do not think i have a failed HPOP. How to better chase a HOP leak?
Long crank to start hot and cold. Acts like missing when its cold tho and when it warms up it runs ok but it will set code weafher warm or cold and u can turn it out with scan tool and drive and it wont come back till restarted again...
View 1 RepliesRemoved my oil rail to replace standpipes/dummies (04 Wavy rail) and now I have huge crank times to start. This is after the initial Huge crank to get it started. Do I have air in the system, or did I bugger something. I did the whole deal very careful. I lifted the rail up very carefully, pipes removed. I lined up the rail nipples with the injectors and evenly pressed it back in place, and then inserted my dummies/standpipe. Tightened the rail to 120 inch lbs then the dummies/standpipe to 60 ft lb. I did my son's '06 a month ago with no troubles. (didn't remove rails though). Once running it sounds perfect, turn it off and re-start and it's a long crank (30 seconds or more). I have not monitored ICP/IPR while running, will try that today.
View 8 RepliesI need to get my oil cooler replaced but that's besides the fact. I drove it on a little trip the other night ran fine. Then went to start it after i was done with what i was doing turned it over didn't start the first time. Cycled the key and cranked it again. Started up drove it back home on the high way no spitting or sputters got off the high way it started idling like crap and shaking as i accelerated but made it home. Let it sit over night and day (was at work) got home to start it and it fired up no problem but still idled funny.
Revved it a couple times and it seemed to clear up so i took it around the block. Floored it and it ran like it was suppose to then go to the other side of the block floored it again and it had no power and sounded like it was running on 4 cylinders. Pulled it back in the driveway idled weird and cleared up again went down the street and floored it ran like a scaled ape and then just died. tried cranking it over and nothing finally got it to start after holding the ignition on ran and then died again. Got it pushed home and decided to fire again after a VERY long crank and it idled for a couple minutes very horrible and died on its own and hasn't started since.
As the title says I am suddenly having a long crank when starting and low oil pressure when when warm (above approximately 100 degrees). IPR goes to 85% when cranking. Stored codes were P2290 and P2291. Other symptoms are low power and what sounds like a power steering pump with low oil whine and low power. (It is not power steering related however, I checked.) I pulled the oil filter and cranked engine and filter bowl filled in less than 10 seconds.
Oil did have a fair bit of air bubbles. Oil has 5000 miles and is Motorcraft 10w30 diesel. I have not added any since the last change. I do not have the new style pump so it's not the STC fitting. What my issue is? I do have AE if any other info is required. Particulars are in sig. The searches I have done combined with the mileage I have lead me to either the low pressure pump is failing, or the high pressure pump has lost the ball bearing out of the side.
I have to replace the #6 glow plug. I confirmed it is bad and the harnes broke when trying to reove it with the proper tool. I ordered a new glow plug, ZD13, and a new drivers side harness.
I have never replaced a glow plug before but it seems pretty straight forward. I watched some youtube videos and did some reading.
I have read some state that you have to loosen the glow plug with a 10mm socket and then take some tubing and push it onto the glow plug to finish loosening it and prevent it from falling into the cylinder. I have read people saying it took them hours with a magnet to get the plug out of the cylinder.
If the plug is threaded and is removed from the threads how is it possible for it to fall past the threads into the cylinder?
Anything special I need to know? Anti-seize on the threads and dielectric grease on the connection? What the torque spec is?
Ok yesterday while driving my truck the glow plug light came on couple times and lost power but the light would turn off and power came back. It has done this before and it was the injector harness grounding out on the engine. I replaced that last time. I checked over the knew one and did not see any chaffing on the harness.
Now this morning I go outside to start it and I can hear my fuel pump and vacuum pump but injectors wouldn't cycle. It has also done this before but I could never figure out why. Last time I tore into it checking through my wiring harness and couldn't find anything. When I put it back together it started fine.
