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. ]
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?
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.
View 14 RepliesI'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?
View 3 RepliesWell 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?
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?
View 4 RepliesI just replaced the glow plugs, gpr, valve cover gasket and harness. When cooled down, cranks but won't fire. Smoke DOES come out the tailpipe. If I plug it in for awhile it fires right up. What else can I do or check?
View 5 RepliesHow to fix SES P0670?? I understand there's a whole procedure on checking fault.
P0670:GPCM Glow plug control module control line failure. Open/grounded circuit, open/shorted GPCM, failed PCM
But how did you resolve problem? replaced GPCM, found open circuit, short --if so where?-- or replaced with updated harness.
(4C3Z-12B568-AA connector upgrade kit as in picture)???
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
I bought this 16' box truck today. 7.3L, 213k, 2003. It doesn't start and the owner gave a really good bottom dollar deal for all these reasons. Showing up armed with Torque Pro and my bluetooth adapter, I proceeded to plug it in and check for rpms, HPOP, Battery voltage, etc. No power to port
Find fuse diagram the owner located and fuse 23 is the OBD port. No fuse in place. He found us a fuse, I plugged it in, viola! Power to the port, TP is in action, ready to troubleshoot.
"Charged" battery, start cranking...no start. No Torque Pro (!) Apparently, the OBD port is cut-off while cranking .... Is there some other fuse or connection that will keep it connected during cranking so I can check for RPMs (no dash gauge for it)?
As soon as I left off the starter, the HPOP on TP showed 1212 then 850, then continued to drop with in about 2 secs. I figure it is getting good HPOP and this is the momentary bleed off.
PO replaced some time ago CPS with Autozone or something in an attempt to start it. No go. I am going to take my "emergency" CPS next time to see if that does it.
Because of the cranking-cutout, I cannot see FIPW. No way to know if the injectors are firing. It had reportedly been running a short time ago (weeks maybe?) and shut off while parked in the parking lot and never started again.
Batteries are low, but new-ish starter and cranks well. With jumpers, able to maintain 10.8v or so while cranking, though it was a bit up and down. I'll take a strong charger with 200amp boost mode next time.
Fuel pump runs. I can feel/hear it when the key is cycled. It has standard Rotella 15w-40w on this 50F day. Reportedly *wants* to be plugged in to start. I plan to switch to 5w-40w synthetic as soon as I can get it home.
It's automatic, pretty sure all van/stock. Here's a pic. Dog box gives good access to turbo and such, but everything else...
One battery under hood, other under cab/body. Has green antifreeze and leak at thermostat.
My goal is to get it running to get it home, about 30 miles, then replace ICP, CPS, IPR, Glowplugs (relay already done), thermostat and top housing and hose, convert to lifetime antifreeze, oil change to 5w-40w synthetic, 2 batteries (test alternator), uppipes or gaskets, Air filter (what upgrades available for this?), UVCH, idler pulleys and belt, replace trans fluid and filter, couple tires, paint inside box, weld and reinforce rear bumper, add radio, check cigarette plugs (think cell phones and gps), general cleanup.
I will have it and run it around 30 days. If it is solid and reliable, off to West Virginia it goes. If not, I'll part it out to get back what I can from it. I am paying for it up front, they are raising donations. But I won't let them pay anything (costs only) for it until I'm satisfied.
They need to run it about 5hrs round trip once a month immediately. That's about 3k miles per year. But I'm sure they will find lots of other uses, such as building supplies, etc. I'm hoping the injectors hold up for a while.
Right now they have multiple vehicles, trailers, drivers donating their time and vehicles (reimbursed for fuel only). It would be much better to take one hauling truck and one or two passenger vehicles... hence the box truck idea.
They distributed approximately 100k lbs of food last year. Not refrigerated, not needed. No CDL needed, about 14k GAVW. The PO has offered his carport where it is parked now, or even to push it into his garage with limited tools (I can bring some) to get it to run. Otherwise...
How to get this home?? Too heavy for my buddy's tow truck from the front. Wheels too far from back of box to reach them from the rear. No tow loops in front for tow bar, UHaul dolly rated at 4k (maybe?)
Dual rear wheels. Anything else I'm missing?

I am a new diesel owner. So I'm not too familiar, how to trouble shoot. I am however, pretty familiar with working on gasoline vehicles. I have a 1999 E-450 Shuttle Bus that will not start after parking it for just 3 days. I live in the area where weather has been above 90 degrees each day. I've charged the batteries, replaced them, and boosted, still no start. I have fuel coming in the bowl. And the battery meter on dash is showing that I'm cranking at around 14 volts.
View 1 RepliesHere's my video of it doing it: [URL].....
98 e-450 rv cutaway with the 7.3 PSD. 219k.
Here's what I have done so far
-New GPR
-New Glow Plugs
-New CPS
-unplugged the PCM, and re-plugged
When it cuts out like the first time in the video, the accelerator pedal does nothing at all. Then once the WTS and CEL go off, it's fine again for a bit.
It seems to only do it when the engine is cold as well. After I had driven it around the block a few times and let it idle, it got better. I was able to drive it 20 miles round trip without it cutting out.
Also, might be related, it has been random on power since I got it. Sometimes I have to floor the accelerator to get up a hill, sometimes I barely need to touch it.
What to check next? It's hard to tell if it's de-fueling or if it's an electrical issue.
2000 Ford 7.3 E450 120,000 miles...
I have changed the CPS twice
I have checked the resistance of the injectors at the IDM connector with a volt meter and the harness reports back good.
The truck will run with ether for a few seconds
I have changed the fuel filter.
The fuel bowl fills quickly
I have unplugged the ICP.
The truck is showing low voltage on the gauge with a good battery. Around 10v
I have connected my 200amp car starter and I never see over 10v. I plan to check the grounds, but I am at a loss.
Everything is difficult because this is a van body so space is limited. I have also plugged in the block heater for an hour and that hasn't made any difference. Where can I get the best price on an AE scanner.
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?
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.

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.
I am currently doing my injectors. Just a quick question. I was trying to get the fuel rail drain plug out but it stripped, actually not on the driver side stripped. I know there is the drain plug on the back of the cylinder. If I drain that and turn the crank over by hand will that drain all the oil and fuel that has drained into the cylinder? I'm really not trying to bend a rod when I turn this thing over. It's A 2001 7.3
View 5 RepliesIt'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.
Could a leaking passenger side glow plug harness cause a "hot no start?
View 5 RepliesPulled p0678, glow plug 8. I've changed out the glow plug on cylinder 1 a few years ago.
Cylinder 8, being on the driver side rear, is it difficult to change out? Should I just pay Ford or another shop to fix this?
