Ford 7.3L Power Stroke (1999-2003) :: Re-torque During Glow Plug Replacement?
I will be changing all the glow plugs in a few days. Should I re-torque the head bolts or anything while I am in there? Don't want to button it back up and then wish I had done something while in there.

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?
Ford 7.3L Power Stroke (1999-2003) :: Glow Plug Change / Oil In Turbo
I'm getting ready to change the glow plugs in my dad's e99, 196k on the clock. When I pulled the air intake tubes I found some oil in the turbo:
The inlet tube also had a bunch of gunk in it too:
Does this look like it is caused by the PCVor is it a bigger issue?
Ford 7.3L Power Stroke (1999-2003) :: Glow Plug Bypass With GPCM?
I've read what little information I can find about making a glow plug bypass, but everything so far applies to trucks with glow plug relays. Since mine is an Excursion I have a GPCM instead of a relay. How I might accomplish this?

Well I just "did" the glow plugs on my recently acquired 99 7.3 and while 7 came out with no problem, one of them gave me more resistance when turning than expected and then "snap". Now here is the interesting part. What actually came out is the threaded top portion of the outer wall, while the rest of the outer wall and the electrode are still in the block. I have done a lot of searching and it seems that usually the electrode detaches from the outer casing and the entire outer casing comes out with only the electrode or part of the electrode stuck in the shaft (usually due to carbon buildup or swollen tip). In this case though, the outer wall of the plug sheared in two, which seems to imply that the outer wall itself is what is stuck in the shaft and not the electrode. The attached picture hopefully explains what I am trying to say.
I can easily latch on to the end of the electrode with some vice grips, but even if I managed to get that out, I would still have the outer wall of the plug in the hole. At the moment I just screwed the threaded part back in to keep the everything from blowing out so I could crank the truck. It cranked right up and seems to run fine. My inclination is to just leave it as is and hope that 7 good glow plugs will do the job, as I have some nightmares about making things worse in trying to make them better. Any chance of the electrode falling into the cylinder if this much of the outer case is still there? How to remove stuck electrodes, etc. but none on a stuck outer casing?
Ford 7.3L Power Stroke (1999-2003) :: Glow Plug Control Module Function?
OK, what does a glow plug control module do? The short bus I got has one on it. It looks like it fits right into the circuit without much, if any, modification. I got one with my short bus and am curious if it would be something worth adding to my pickup. So...what does it do and could I/should I install it?

I have no ground to glow plug solenoid, wiring is ok right up to the computer. Where I should go from there?
Its a 2001 E450 PSD. glow plugs not coming on at all.
should I be checking an engine temp sensor?
I don't have a wiring diagram so I am going in somewhat blind. ]

When the block is cold my truck will not start. If i keep the block heater plugged in it will crank but is still a long start. I have tried just about everything i can think of and it is way too much to list so i will give as much info as i can.
New- gpr, glow plugs, HPOP, batteries, starter, fuses, valve cover harness/ injector and glow plug wiring, vacuum lines. I have checked out just about everything remotely possible.
Ford 6.0L Power Stroke Diesel :: Truck Lost Power And RPMs Dropped Only Glow Plug Light Came On
It's a 2004 6.0 excursion with about 190,000 miles. At 185,000 I pulled the motor and did new oem head gaskets, Arp head studs, bulletproof egr cooler and oil cooler system, bulletproof 48v ficm, strictly diesel regulated return, and I've been running gear heads srl tune before and after the truck was rebuilt.
Recently the truck has been acting up at random times. While running the gear head srl tune, the truck will lose power, the boost gauge on my edge insight will get stuck along with Icp psi, the water in fuel light and glow plug light will come on, and then after a few seconds it will clear itself and run fine. Last night I was on a two lane road and putting my foot into it and the truck did the same thing where it loses power, but this time the truck actually died on me while I was cruising at 60.
Same lights were on but this time the cruise control light fluttered while the truck was in the midst of dying. I tried restarting it and it took two sets of cranking before it fired and stayed running. On the way home I babied it and the truck lost power and the Rpms dropped and only the glow plug light came on. Got home and ran codes and I got camshaft and crankshaft position sensor codes and I tuned it back to stock, drove it around, and the truck ran fine, but while on a stock tune I am getting a egr valve code.

Ford 6.0L Power Stroke Diesel :: 2003 - Leaking From The Glow Plug Harness
Got a 2003 6.0 that seems to be leaking from the glow plug harness. How hard would it be to just replace them? I've heard that trying to remove these things can be a pain because they almost always break. But if I'm just going to replace them who cares right?
Is there anything I need to be careful about? Or can I just rip em on out? Also I've noticed two different styles of harness should I replace mine with the other style or just keep it the same? And yes those valve cover nuts are loose. I'm aware
Ford 7.3L Power Stroke (1999-2003) :: Slight Hesitation In Throttle While Cruising / Truck Stalled Won't Fire
Last night I bought 2000 F250, 346k on it... Crew cab short bed 4x4 with ranch hand bumpers like I wanted .... Headed back home (Miami FL ~1100mi) and covered about 200 miles @70-75mph before i ran into few problems ....
First off, while cruising I noticed slight hesitation in the throttle, with loss of speed regardless of pedal pressure, noticeable on inclines. It would go away on downhill and get smooth response again and pick up speed. This went on for about 40 miles.
Then I noticed heater blower stop blowing hot and start blowing cold, without me changing any settings. At the same moment, I noticed temp gauge move up and I hit next exit offramp to check what's up. During right turn at the end of off ramp truck stalled. Pulled to the shoulder, and popped hood.
Noticed empty degass/overflow bottle. Carefully opened lid and water gushed up to the top. When all pressure slowly released, water pulled down and emptied the bottle. Both upper and lower radiator hoses are empty. Engine oil has no traces of water tho. There were no leaks under the truck. I then tried to fire up the truck to get me to the gas station 1/8th mile away.
No crank in Park. WTS comes on and goes off. Cranks in Neutral, RPMs come up some, oil pressure shoots up to normal running position, but won't fire. Tried a while then gave up as not to kill starter and batteries completely.
Fuel pump works 20 sec then shuts off. There is fuel in bowl. I covered 140 miles since last full fill up, so not fuel pickup issue I don't think.
Summary
Have crank
Have RPM
Have oil pressure
Have fuel
Have (had) batteries, now not so hot
It's cold out ....
Ford 7.3L Power Stroke (1999-2003) :: Cylinder Head Fuel And Oil Rail Plug ORing Replacement
Is this job worth doing as a preventative maintenance item? I replaced the rear fuel rail plug (aka banjo bolt) o-rings because they were very easy to get to with the up-pipes out. But the cylinder head plug in the rear is pretty high up and even with the up-pipes out, there isn't enough room to get a breaker in there that's long enough and has enough movement to loosen it. The front would be easier to get to, but both accessory brackets need to come off to get to them on both sides.
As far as I know, none of them leak but they're all 17 years old... BTW in case you haven't been following, I'm doing up-pipes, injectors, turbo, rebuilt HPOP & fuel bowl, boots & clamps, etc. so I'm trying to knock out any PM items while I have it apart.

View 7 RepliesFord 7.3L Power Stroke (1999-2003) :: 2002 - Long Crank Even Plugged In
Little background- this is my first winter in a diesel truck. When I purchased it- it had 4 glow plug codes. Everyone around me just told me to plug it in and fix it later, that if I plugged it in, glow plugs don't matter much.
Had hard starts all last week with temps down to -20, turns out my block heater wasn't turning on due to a bad cord. Replaced cord end today. Let the oil temp get up to around 60F according to torque pro.
Still had a long crank despite warmer oil (15ish outside). Batteries dip to around 10V when plugs are on, then cranks at around 11V. Lots of white smoke which I know is normal.
I still had to fight with it a little bit to get it to start, as soon as she was actually going- runs flawlessly, no lope, no smoke. Runs and drives flawlessly. If I turn it off, she fires right back up instantly every time without hesitation, until she cools off again.
From what I'm seeing I'm thinking my batteries are fine, and my starter is probably fine. Are glow plugs making this big of a difference even though the truck is plugged in?
Truck has 0 codes when warm, 0 blow by, drives fantastic, Just under 300k miles. The only thing I'm thinking of is the glow plugs need swapped. I have a set of ZD11s sitting in the truck waiting for a warm day.
Ford 7.3L Power Stroke (1999-2003) :: 2001 - OBDLink MX Plugged In Then Start Otherwise Won't?
My 2001 7.3L Diesel has 222,000 miles on it. Yesterday I shut it off at a drive through window, went to start it and it just cranked, no start. The engine light and the wait to start light did not come on. I plugged in a code reader this morning and when I turned the key I heard a buzz and a click, I noticed the engine light and the wait to start light came on. I cranked it over and it started right up, when I unplugged the code reader, it died. Plug it back in and it runs, dies every time I unplug it.

My 00 F350 has never started when the temps were below 25 unless it was plugged in. This year is no different, but now it won't start when it's plugged in. It just turned 200K and I know things have to be checked, but I don't like doing them in the winter so I was hoping to make it through this winter and fix things. I needed to use the truck the other day so I plugged it in before I went to bed, It wouldn't start, so I got looking, crawled under the truck and the block around the heater was cold, checked the plug with an ohm meter and it showed that there was an open, so I checked the cord, sure enough there's a splice in it, with a broken wire, so I fix all three splices, check it again and it's still open, under the truck again, and find another splice at the end of the factory wire loom with a broke wire, got them replaced, got a good reading with the meter, and now I'm back in business, Plugged it in for a couple of hours, hit the key and it fired like it was new. Well not that good but it did start.

Just happened to check codes today for fun and found something interesting. I've known about 2 or 3 glow plug codes since last winter but I looked today and I have a code for every single circuit. Thought that was kind of odd.... I already have 8 brand new plugs and both harnesses from Autonation sitting in the back seat, was just waiting till the fall to change them out. At 176k on the originals I decided to change them all. But now I'm thinking the GPCM may be faulty as well.

Ford 6.0L Power Stroke Diesel :: Glow Plug Light Came On - Lost Power - No Injector Cycle
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.
