Ford 7.3L Power Stroke (1999-2003) :: Studder When Cold After Sitting For Long Period
Apr 29, 2017
I think I'm going to buy a late 99 CCLB six speed manual truck that's probably been sitting all of a year, maybe longer. Prior to being parked the truck ran flawless. 6 months after parking it he decided to sell it and when driving it, it has a miss when its cold and blows a little white smoke when accelerating. Appears to clear off and run normal after its warm. So he decided to investigate it and re-o-ringed the injectors and checked other things out.
He's determined he thinks it has a weak hpop. Not sure I'm sold on this. Fast forward six months and now I'm pretty sure I'm going to buy it. Drove it yesterday and same thing, first 4 or 5 miles kinda studders or misses but after that runs smooth and has no issue. No longer blows white smoke at all or anything. Obviously the fuel is old as hell, other than that what is everyone's thoughts?

I recently parked my f-350 dually on a 15degree slope during a rainy period about 2 months ago. I went in recently to start it and it would'nt start. I replaced the two batteries in my attempt. I turn on the key in the on position, wait for the "Wait for Start" light to turn off, then it cranks really fast , then slows down and it won't start. Tried to take off the fuel filter but is there a special tool to take the cover off. It started real fine prior to this. Also I put in 5 gallons of diesel .

After setting up about 8 days, my truck has long start now. It starts but takes longer.
I plan to start with charging the batteries over night and see what happens. How old they are since I bought it last year. The batteries did drag just a tad when it started but seem to be back up after driving.
New ICP few months back. I have a couple scan tools.... Forscan and Dash Command. What to look for?
Last note: it starts fine, just takes longer now. Is plan to start tonight.

The 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.

My ride again has started to develop a small studder during acceleration. It seems like only when it's cold. But when the temps are at normal it's not there.
At work now, but would like to get a heads up on it by the time I get home. To know what to look for.
No modes, no codes nothing but the studder.
Using T6 every 5000klm, fuel filter every 15000klm.
I have a fuel filter at home and will first replace it, before anything else.
BTW, all filter are OEM
About a year ago I had something similar. But I through some codes. I will look them up here at FTE.

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.

I've got a99 F2 50 super duty with a 2000 2001 motor. I got the truck in the beginning of last winter so this is my first summer with it.
When I first got the truck there are injector issues with the truck. Since I fix the issues there has been little problems out of the truck however it's still suffered misfires when Cold but once up to operating temperature it was fine. Yesterday I had to go with a friend before leaving for the trip I checked the oil it was full and appeared normal the trip was about 150 miles. I came home park the truck after everything was done. This morning I came out started the truck everything acted as it should... truck fired right up everything was great went and dropped off my trailer at the yard come back got fuel when I come back out from paying for the fuel the truck took about 30 seconds to fire up I checked my gauges and torque pro and everything seemed normal. So on my way I went.
I drove about 10 miles on the highway to the place I had to be when I got done doing my business I came back out to start my truck and it did the same thing this time however it took longer to start I managed to drive about a mile down the road when I noticed my old pressure gauge flickering and my Oil pressure light on I immediately shut it down and coasted into O'Reilly's parking lot I check the oil in the truck and it was empty according to the stick I added two whole gallon.... With it filled back up down the road I went. So currently the truck is still suffering from a long hard starts it takes 30 to 45 seconds before it all actually fire up once it fires up everything appears to be fine however the truck is slowly smoking a bluish black color... It's never done this before however I've never had this truck in the middle of summer when it's real hot out I don't think this is normal.
The truck doesn't appear to be down on any power actually it, acts as if it might've picked up of some power it is felt real peppy today compared to other days. Also I might note that about a week or two ago I started smelling diesel like either really rich diesel or raw diesel wasn't too bad but I just got whiffs of it for now and then. Now there is a burn oil smell present from the exhaust. Like I was saying earlier when I first got the truck I had to service the injector O-rings... I was told that the miss firing when cold was caused by the Poppitz sticking. The misfire hasn't been present since it got a little warm outside like I was saying it was only when the vehicle is cold.... Just thought I would mention the injector issue not sure if it's relative or not..... My thoughts are it's back to an injector issue or O-rings or possibly did I wipe the motor when it ran out of oil. I am not aware of where the oil went as there is been no leaks or drips.

2005 Ex with 6.0. It has been bulletproofed. But has had a long crank after sitting for over 5 hours. I was starting to think glowplugs but no codes, Then thinking FICM, nope voltage has always been good. After I run the truck for a few miles if I kill it. It would crank right up. No issues. Only happened after it sat for awhile. I knew it had to do with HPOP system since it took about 5 to 8 seconds to show over 500PSI.
The passenger side does not have a leak since the oil is to the top of ICP sensor. When I was going to remove it. So I took off the drivers side. I inspected the dummy plug. No issues there "they are the 12mm with teflon plugs" I inspected the stand pipe. No issues there either. I inspected the small test port on the top of the rail. No issues there either. So I decided to air test it. So I used my auto-ingenuity to close the IPR valve after I heard all the oil blow out.
Then after sitting with 120 psi of air for about 10 minutes. I hear a bubbling sound coming from the Drivers side Rail. It was a plug I have never seen mentioned here. It is at the back of the rail. I removed it and sure enough the oring is split in 2. I went to ford and picked up a new Oring it was like $4. It also looks like its a different material. I am still in the process of putting the truck back together so i have not started it back up. But I am pretty sure this was my problem.

I bought this truck from a family member 03 7.3, it's been a park not garaged sense 09 when my cousin the original owner died. Was strong running when park. I started it yesterday after changing solenoid, hot battery, and I put some fuel stabilizer and 5 gallons of diesel in it. But I cut it off maybe two minutes after because I didn't want to break anything before I found out what's a few tips of things to do before I put her onda road because this is my first go round buying a diesel truck

On the way to work, the truck seemed to have a miss at idle and the CE light came on. Long crank to start leaving work, and truck starts losing power and eventually died. No smoke while it was losing power. Towed it home and checked the fuel pump and lines for blockage and found nothing.
2003 7.3 F-250 430K miles
strong cranking but no start no smoke out exhaust
Oil changed recently
IPR changed
Both UVCH gaskets and pigtails have been repaired.
ICP sensor and harness changed, also disconnected no change in cranking.
fuel filter changed today (no oil in bowl)
3/4 tank of fuel
dash gauge for lpop goes up to normal range during cranking and oil light turns off.
WTS light comes on and turns off as normal
tach gauge moves up between 100-200 during cranking
fuel pump turns on and pressurizes system like normal and turns off.
Ordered AE for the truck, and it directed me to the passenger side bank high open. Fixed the harness on that side and still nothing.
Sent off the IDM and it passed with flying colors
So now i'm leaning towards the HPOP, but would hate to fork over the cash for it and still not get anywhere. I'm going to take the valve covers back off and check the discharge ports for the injectors tomorrow.

My excursion suddenly lost power after sitting in a long traffic jam. I have a scan gauge II set up and didn't see any signs of over heating however when I went to accelerate back up to highway speed my motor revved up to 3000 rpm and just lost power I ended creeping on the side of the road at about 15 mph and barely maintaining that. The motor was not willing to revv up. I reached a spot to pull over and shut it down for about 15 minutes and started back up and drove off with no noticable issues. I have 211,000 miles on this motor and I am going to change my coil packs, I think they have been there since the truck was sold new....I changed four of them to address a miss and have six left, I will also be changing my fuel filter. We are about to pull our camper across country....about 1400 miles..

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.

Parts came from Riffraft Diesel Performance. A set of "o" rings for the injectors. High flow CVD fittings for the fuel lines. Turbo rebuild kit. (its got 210,000+ miles) Anti Surge compressor wheel.(ok its not part of the oil problem)
Photos to come. I will take during the rebuild.

the wife's '01 Excursion has developed a new idling quirk. While sitting, it will briefly drop rpm's. You can hear it, and see it on the tach gauge. No other noises or problems, except for the brief drop in rpm's.

I recently did the following work:
New Injectors
New T500 Hpop
New IPR
New ICP Sensor
New UVCH/Glowplugs
New starter
Been cranking about 15-30 seconds each time about a dozen times now. I've pulled the icp and the hp crossover and have oil flowing at each.
ICP builds to about 240 psi and at a 98% duty cycle....so I assume there's still some air in the system. I"m not getting any sense that the engine is trying to hit. Do i just keep cranking?

Background on the vehicle, Last week installed Swamps 200cc/30% injectors with a 38r. Had swamps reburn my chip for the new upgrades.
But heres the problem i noticed starting the truck was a little harder ( longer cranking ) till it would start never thought of anything since i read air gets in and can cause it but then yesterday and today its taken 30 minutes to start the truck since i have to do a trial and error.
The truck just seems like the batteries are being drained or something along those lines. i also noticed my gauges keep resetting back to blue( default color). Today I plugged a battery charger up all good voltage i charged them so both read 14v and still no start. So a couple of attempts at starting with chip in and ICP on nothing
I unhook the chip and ICP get a half start then eventually it starts. After then i can hook it all back up and it starts good for the rest of the day but for what ever reason after it sits all night it doesn't want to start up right away. I'd like to figure it out today since id rather not wake up at 4am and attempt to do this all before work each day.
I noticed that my gauges would reset to the default color after each turn off. So i unscrewed my ECU and then redid that to make sure its tight. along with making sure the chip is seated properly. after that it stopped resting my gauges. Whether that's the issue or not i cant say but ive been checking my HPOP oil level since i stopped driving it around 1400. and hasn't changed oil levels are good. I plan on starting it before I go to bed around 2200-2300 just to check and see what happens.

I have a 2001 E-350 w/7.3. When I start the truck first thing or when engine is cooled down it starts fine. I checked the high pressure pump pressure and it is 500 - 600 psi start up great. But when engine warms and try to start it it has long crank before starting. I checked pressure and it is between 425 to0 450 and takes awhile for it to get to 500 or better. Is this a cause of the high pressure oil pump ? I changed the oil and still does same thing. Also I noticed that after engine is hot and I try to start it, while cranking the engine the oil gauge does not move. I don't know if it supposed to when you crank it or not. I thought on other 7.3's I've worked on that the gauge builds up pressure....

Sitting in stopped traffic for about 45 minutes and AC slowly starts blowing warmer air. Temp about 95 and very humid. Felt like AC just freezing up, but no frost on anything when I looked under hood. Hoping freon problem. About to start looking at it this morning.

So the water pump on my early 99 (158k miles) is starting to leak just sitting in the driveway, did a little research last night and read a few write ups. Just wondering if any tips or tricks I could use to make this go easier. Also any list of parts I should replace and/or might need. I read on one write up about replacing it with an Airtex water pump and was wondering about what people thought of those, I would rather fix it right then just go with the cheapest parts. Possibly there are better brand water pumps out there?

This is wife typing in middle of trip. Today we drove almost 300 miles down the road before it stuttered. We lost the tach but nothing else. No check engine lights. It has done it a few times since. Watching with Torque and don't see anything there. Have 100 miles to go and it's happening more frequently. Replaced CPS 4 weeks ago with a Ford grey. Running down road it's 95 day. Oil was checked to be good at 211, transmission 182, EGT 790, pulling enclosed 6x12 cargo trailer. What can I check?

If I leave my truck sit for a couple of days, the batteries are noticeably weaker. It's fine overnight, but two nights and it's slow to crank. Three and it won't start without charging the batteries. I checked for a drain last night and found that it was drawing 1.2 amps.
That seems like a lot, no?
