Ford 7.3L Power Stroke (1999-2003) :: 2000 - Hard To Start On Cold - Oil Leaking?
Dec 18, 2016
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?

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.

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?

When 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?

It'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.

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....

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.

2000 F350 with 340000 on it, have had it for the last 140000. It's an old service truck from south west gas with one owner in between them and me and he put about 5000 on it. I have the big cylinder open air filter, billet compressor wheel, 4" exhaust all the way and an Edge tuner. Don't have any codes I can pull with the tuner. Have been good to me so fare only need regular maintenance, but always had smoke out oil filler with a little pulse.
2500 ago I changed oil and add 1/4 of Lucas oil. 3 days ago when I started in the morning it smoked white smoke out the exhaust as a steam train and idle rough, but cleared up as I went down the street and will do so every time I start cold or warm. Ok, might need new GP, did that yesterday yet the same. Now I start checking stuff and have smoke out the oil filler as a steam train so the cap won't stay.
I know it sound like alot of problems, just try to verify some of them. The smoke out oil filler is blow by? The smoke on start up is that related to bad injectors? Can a bad injector dumping fuel create the blow by? Coolant level ok Transmission fluid level ok Engine oil Rotella T6 added 3 quarter in 2500 miles. I do not have a scanner or any other advance test tools.

I recently purchased a 2000 7.3, when it's started cold it's lopes at start up unless I give it some gas and then it's perfectly fine. If the truck is plugged into the engine block heater it starts normal. I changed the oil the day after I bought it and put 15w-40 in it and then the rough idle started. So I don't know if it was like this before or because of the thicker oil I put into in the cold. It also has a service engine soon light on and the code that comes up when read is to the icp sensor. When looking st the sensor the blue wire going to it looks cut and is disconnected. How would I reconnect these wires and see if that makes the check engine light go off.

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.

I have a 2000 f250 super duty extended cab with the 7.3 diesel and auto tranny which the tranny was rebuilt by Samco about 7 years ago and I have 337,000 miles on engine I had a oil leak from I believe my oil cooler which I fixed, but I am still losing oil, about a gallon or more every other day and in that time frame I am only driving maybe 30 miles. I have no drips, and I seriously don't believe it's burning because the truck is not smoking even when you rev the motor up. the bottom of the rear of motor is coated with oil plus as is part of tranny and some front of motor bottom. What to look for?

We're currently RV camping in the Wyoming Wind River Range at 8500 ft and is getting to freezing at night. The past two mornings the truck has been very difficult to start and I got quite a bit of smoke. This morning it took two or three tries but I got it going.

Iam looking at a 2000 7.3 Powerstroke that has some problems first it is hard to start cranks like it has a dead cyl. Second after starting it has no power not even enough to move. At first it would only run if held wide open but once it warmed up it would idle and rev and move but barely still had a miss. The weird thing is it did not smoke blue-black or white also no strong smell of diesel and no smell of oil at all. The truck has 230ish miles and there are no maintenance records.air filter was new.

Here'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.

Truck is a 2000 7.3 PSD Exursion, 300k miles, automatic. Does this when cold, I let warm up for 5 minutes before this happened as its been doing it. Going to plug in tonight, was about 40-50 degrees out.
What is causing this shutter? Injectors? After I get off my dirt road to street it runs fine, also notice the ebpv. Seems to do shutter most when reversing.

My e99 f250 has been getting harder and harder to start over the last year.
I think one of my batteries is dying or dead but it still cranks fast while it does.
For instance when I tried starting today it seemed to crank just like normal but their was some relay clicking inside the cab that was abnormal.
My understanding is aside from cranking no power is required to start the motor? what if the dead battery is taking some cranking amps from the good battery preventing the computer from getting juice?
would the truck throw a code if it was a glow plug?
