Ford 7.3L Power Stroke (1999-2003) :: 2001 - Won't Start When Motor Cold?


May 1, 2015

I have. 2001 excursion with a 7.3l deisel. 167100 miles

It runs great but if it sets over night when the motor is cold it will not start.

You have to plug the block heater in for about an hour or more for it to start.

To me it seems like glow plugs are not working? It had new glow plugs out in from the po.

Ford 7.3L Power Stroke (1999-2003) :: Start Rough When Cold - Injectors Not Working On 165k Motor?

Replaced o-rings, injector cups, glow plugs and UVCH with all motorcraft parts 2 years ago and the ICP, IPR and resealed the HPOP last year. I use rotella 15W-40 oil. It has been hard to start when it is cold and runs rough with little power until warm for a few seasons now when it is cold outside. There are no fault codes or issues otherwise with the mostly stock truck. A buzz test when the engine is cold only #6 sounds strong and #8 isn't quite as bad as the others but the others are hardly audible.

Cause:

1) Can 6 to 7 injectors really go bad in 165k miles? If it is injectors I believe the Alliant look to be the way to go with type ADs?

2) Since it is like flipping a switch and the number of injectors effected is it possibly the 0.1% of the time it is the IDM when there is a miss and no SES. From my searching and swampdiesel if there is a miss and no SES it is 99.9% it is not the IDM or harness since it actively checks continuity.

Ford 7.3L Power Stroke (1999-2003) :: 2001 - Cylinder Missing Until Motor Warms Up

My feed truck (2001 ext cab 4x4 7.3 198k) had a cold starting issue I fixed with new gp relay. Now I noticed when it gets down below 30 degrees it has a cylinder miss until motor warms up. I don't doubt injectors are in my future. I was wondering though if that is common for worn injectors or if maybe something else has gone haywire and how long can I run it like that before something else tears up? after about 7-10 min the miss goes away and I don't notice it. I would like to get through the winter before messing with it or having injectors put in it...

Ford 7.3L Power Stroke (1999-2003) :: Motor Turned Over / Loading Up And Won't Start

I have a 2000 F350 with a 7.3 I have just set a brand new motor in this truck with everything in it new including the transmission injectors are 175/146 from Thoroughbred Diesel. The engine is Bored 40 over studded heads return regulator system as well as a pre pump filter and a javelin and Hutch mod on the tank. When we went to start this new motor the motor turned over and sounded like it was going to fire off pretty quick but instead I'm just getting white smoke and lots of it.

I failed to mention that the injectors are single shot vs. Split shot and then I did have the programmer Tuned to these injectors through thoroughbred there is no fuel in the oil no water in the oil no oil in the water everything seems to be good all the pressures seem to be good and at this point I am lost no one that I have found in the area, where to begin. Seems to me that this is a loading up issue and it seems to me that the only thing that could be causing this would be programming but I don't know.

Ford 7.3L Power Stroke (1999-2003) :: 2000 F350 Would Not Start / Motor Fire For A Split Second

The night temperture was only about 37 degrees. But every morning my 2000 F-350 7.3 crew cab 188,000 on it would not start. The first try there would be a split second where the motor would fire, but that would be it. I had to plug the engine block heater into my generator for at least an hour before it would start. I don't see how all the glow plugs could be bad at once??

Ford 7.3L Power Stroke (1999-2003) :: 2002 - Motor Suddenly Started Shuttering And Then Shut Off - No Start

I am fairly new to powerstrokes, but have a general understanding how the 7.3l operates, and how the fuel system works.

The problem i am experiencing is a crank, no start. The truck has been great for the year and a half that i have owned it. Always cranked great and never any starting or running issues. One day upon cranking, i started the motor; it started normal running good for a minute until the motor suddenly started shuttering and then the motor shut off, happened rather quickly. The truck started up immediately after that and died....repeating the shutter until dead. Now the truck will not start.

Specs on truck:
2002 7.3l
230,000 miles
Manual transmission

Here's what i have replaced so far:
New parts include:
IPR (motorcraft)
ICP (motorcraft)
EBPV (napa)
CPS (napa)
IDM (reman)

Here are some of the diagnostic values i have collected during cranking: (FYI: i am a little confused on what the values mean and what they should be in order for the motor to start):
ICP: 2218 psi
ICP duty cycle: 41%
EBP: 265 kpa
battery voltage: 12.0
Rpm: 355

Things i have checked so far:
Oil is new and level is good.
WTS light cycles as normal.
Fuel bowl is full and over flows with cap off while cranking.
Fuel tank is above half.
Glow plug relay is good.
I was throwing a code for the PCM, but i removed the bully dog tuner and the code has since cleared.
HPOP oil is an inch below full.
I made a gauge set and dead headed HPOP yielding 1500psi.
Upon cranking i am seeing some smoke, i guess, but its kind of hard to tell from the drivers seat.

This is where i am at so far. I don't have a way to buzz test the injectors or tell if they are leaking past the orings. I have the valve covers removed, but i have been putting off pulling the injectors to replace the orings.

Ford 7.3L Power Stroke (1999-2003) :: Cold Crank No Start

I have an 02 f250 230,000, first 7.3. I've owned it since Oct and put less than 6,000 miles on it. I have another cold crank no start. New glow plugs and Glow plug relay last weekend. Worked fine that weekend. It sat all week, then crank no start fri night, it was like 70 degrees for the high that day. Plugged it in over night and it started. Did not fire right up cranked it for a couple seconds. I drove it all day, started every time. Valve covers have 5,000 miles on them. Fuel Filter heater fuse not blown. But don't know how to check it for sure. And don't know where to go with it from here. Getting frustrated with crank no starts. No troubles found.

Ford 7.3L Power Stroke (1999-2003) :: Rough Start At Cold?

I just started having a cold start problem with my '02 Excursion this fall and I'm at my wit's end trying to fix it. Truck starts fine above about 45 degrees and when it's warm. If I plug in the block heater it also starts fine in the cold. If it's not too cold I can eventually get it started by continuing to crank it. It blows white smoke while cranking and for a few seconds after it finally turns over. Smells like fuel. Runs rough for 30 sec after starting when it finally turns over. Definitely seems like glow plugs aren't working. This truck started no problem on GPs alone without plugging in down to -20 deg F before this year.

I started by cleaning all battery connections, including the two ground posts on the engine block, I replaced one bad battery (diagnosed by Autozone; other one was OK), I checked the resistance of the glow plugs (only a few years old with about 30k miles on them) through the connectors on the GP control module (all were about 1 ohm), and confirmed 12V at the power pins in the GP control module connectors. I then replaced the GP control module and the problem is still present. Battery voltage drops from about 12.6 V before I start the GP cycle to about 12V when I turn the key to "ON" and the GP light comes on. How much should the voltage drop when the GPs are on? What the heck else could be wrong??

Ford 7.3L Power Stroke (1999-2003) :: Truck Would Not Start When Cold Outside

Ok truck would not start when cold outside. So I put a gpr on truck. Truck alt would only put out 11.5 ... After I put it on. So I put 4 new alts on all read the same 11.5 and the battery's would drain over night. Turns out they gave me a starter relay. So I have the proper one now. Now when u turn the key the everything is flashing the dash dome light buzzer. But take one of the small wired off the gpr, it stops but I have no power to the starter. It's been 2 months of hell trying to figure it out.

Ford 7.3L Power Stroke (1999-2003) :: Just Crank When Try To Start Cold

So back ground is as such. Truck started fine before I replaced the hpop with t500 and did the driven diesel regulated return. I have double checked everything is plugged in. Now when I try to start it cold it will just crank. Yes I get smoke and oil pressure both places. If I give it a shot of ether it will start right up and run fine all day. What am I missing? Yes I know ether bad.

Ford 7.3L Power Stroke (1999-2003) :: 2001 - Truck Runs Rough When Cold

I have a 2001 7.3 with 259,000 miles. It does not get too cold here, however over the past few winters when the temp is below 50 at night the first minute or two of running out of the neighborhood is tough going unless I let it heat up. It has been getting worse over the past few years and now if its even 55 or 60 I need to let it heat up. Glow plugs? Injectors?

Ford 7.3L Power Stroke (1999-2003) :: Long Cold Crank / Hot No Start

I 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.

Ford 7.3L Power Stroke (1999-2003) :: Hard To Start Cold - No Codes

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?

Ford 7.3L Power Stroke (1999-2003) :: SES Light On / Shuddering At 40 - 55 MPH And Cold Start

I bought a 99 f-250 7.3 a month or so ago and am impressed with the level of knowledge and hospitality you all show. This is my first diesel so I am completely new to a lot of the issues that occur with one and many of the diagnostic tests needed to troubleshoot.

When I purchased the truck the guy said it was very cold natured and I would have to plug in the block heater if it got chilly out. I didn't realize just how bad that problem was and have since had to keep it plugged in even on very mild nights to get a quick start. I have been very careful to let it warm up for 15-20 mins before I start driving it.

Also, I have noticed at around 40-55 MPH and light pressure on the gas I get a shudder, it was worse before I added a friction modifier to the oil but it is still there constant in overdrive.

As I was driving two or three days ago in a light rain (the first since I bought the truck) I noticed the SES pop on and stay on. Being new to the diesel world I immediately pulled into Autozone and tried to get a code, but with no luck. The truck has been running a bit rougher since the light came on and I am noticing a marginal power loss.

So my questions are: Where can I get the codes pulled off? I have been looking at buying a scan tool but the AE is out of my price range and the other options seem to have mixed results. Also, do any of the problems seem to be related or could it just be a few different issues that need to be ferreted out? From what I've read it seems possible for the UVCH to be the issue here, is that correct?

Again, I am really new to diesels so I may have been having loss of power even before this and not known it due to my inexperience.

Ford 7.3L Power Stroke (1999-2003) :: Rough Start At Cold Temperature?

I am intrigued by this engine and it's cold start issues so I am trying things out to see what works. If I plug it in it starts like summertime. If it's as cold as 30* out I run the glow plugs for two minutes and it starts without much effort and once running purrs like a kitten, no chug a lug, no romping, little smoke. When it gets down into the 20's I run the glow plugs for two two minute cycles, a little more cranking time but starts same as above. Down to 18* and I cycle the glow plugs twice for two minutes and it cranks, tries to start but won't. Key off, back on for two more minutes and it starts right up like a warm summer day. It hasn't been colder than 18* here this year so this is the end of my report for now. I haven't taken the time to check the glow plugs which is on my list but this summer it'll get done.

Ford 7.3L Power Stroke (1999-2003) :: 2001 F250 Truck Has Always Had Difficulty Starting Cold

2001 F250 7.3l 294k miles

Ok so truck has always had difficulty starting cold since I got it about 12k miles ago. Replaced glow plugs, that made things slightly better but still no start unless temp gauge was in that first line above the C. Changed to Rotella, immediately after oil change starts better and at slightly colder temps.

Since getting the truck when you turn the ignition on you can hear a 'whistling' type noise which I believe is the fuel system pressurising. That used to last as long as the chimes did when you first turn the ignition on. More recently it lasts a lot longer.

Towed recently and had intermittent check engine light - believe this could be HPOP related, haven't checked codes yet as we're on vacation. No oil in the valley. But I do have a little oil carry over in the turbo intercooler pipes.

Truck slightly sluggish at setting off initially and then picks up reasonably well when not towing but my Dyno says I'm putting a bit more pedal to get the same performance from say two months ago

Pretty sure injectors haven't been changed since truck was new but can't be absolutely certain as there is no history. I was surmising this is probably both a HPOP and injector age issue but only from what I've found searching...

Ford 7.3L Power Stroke (1999-2003) :: 2000 - Smoke On Cold Start - Oil Filter?

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.

Ford 7.3L Power Stroke (1999-2003) :: Hard Cold Start / Now EBPV Not Working

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.

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

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?
