Ford 7.3L Power Stroke (1999-2003) :: Service Engine Light At Acceleration Only
So i replaced the faulty injector and the truck starts up great and runs great. The only issue is that now when i accelerate, the SES light comes on until i let it up a little. If i am at cruising speed or just a steady speed the light goes off. I havent checked for codes yet because the light didnt stay on. I have AE and know how to use most of it. Is there something i should be looking at? Could it have something to do with the Blue/Gray CPS i installed or maybe there could still be an air bubble in the oil rail from when i drained the rail ? I have a DP tuner and stage-1 injectors. Regardless it sure is nice to have my truck back out on the road. It was a horrible 3 weeks without it.

Truck started losing power then service engine light came on, drove about another mile then it just stalled ( almost home lees than a 1/4 mile). Got out open hood oil everywhere on top of motor. Looked under truck and oil all over the road. Looked back where I was driving a line of oil as far an I could see. Checked oil barely any on stick. Where should I start hpop or plug?

The SES light in my 2001 7.3 came on about a month ago while I was towing a light trailer in the SoCal mountains. When I got home I spent about 2 weeks replacing the injector o-rings and glow plugs. I discovered while I was in there that the head bolts on the driver's side where loose. I retorqued them to spec.
Both batteries were disconnected for the 2 weeks. When I started the truck the SES light was still on.
My Torque Pro app isn't showing any error codes, and is reading live data correctly. (I didn't have the app when the light first came on; I only purchased it after I finished the repairs). Am I missing something? Is the SES light not necessarily connected to fault codes? If so, wouldn't it reset after 2 weeks with the batteries disconnected?
Ford 7.3L Power Stroke (1999-2003) :: 2001 F350 - Service Engine Soon Light Is On
I have a 2001 F350 and my service engine soon light came on. For a while it went on and off and every time it came on the engine ran rough and I lost some power. I pulled the valve covers and checked the UCVH and everything was fine that I can tell I even made the shims out of quarters and put them in. After putting it all back together its still doing the same thing.
View 1 RepliesFord 7.3L Power Stroke (1999-2003) :: P1211 Code With Constant Service Engine Light
I was on the way back from the weekend trip and got a service engine soon light. I didn't notice any lack of power, rough idle or hard starting cold or hot. So we pushed on home. I checked the codes and it is the P1211.
Doing some research it seems the ICP is not as expected so I hooked up my phone with the Torque app and the IPR and ICP seem to be close to normal at idle and running. I din't see any high IPR %.
At idle the IPR was around 15.5 cold and 10.1 after a short run to the store and back when it warmed up a bit. ICP was around 690-720 cold and 470-490 when i got back.
Does that seem like normal readings? I cleared the codes and the CEL comes back on right away after starting the truck. I do have a TS performance chip that I will take out and see if that could be causing any problems. What else should I be looking into?
Ford 7.3L Power Stroke (1999-2003) :: Truck Will Accelerate Quickly With Slightest Touch Of Gas Pedal - Service Engine Soon Light On
So about 3-4 times per day, my truck will accelerate very quickly with the slightest touch of the gas pedal, then followed by the service engine soon light...I checked for any codes to see what I may need to fix, but no codes are found.
What this could be? I am also having issues to where I a few times per day I have to put my truck in neutral to get it to start instead of in park...could the two be related?
Ford 7.3L Power Stroke (1999-2003) :: F250 - Code P1211 - Service Engine Light Pops Up Going Steep Hill
I have 2003 f250 7.3 automatic 181,000 miles completely stock. Never had chip,tuner or anything on it. I am second owner and got it when it had 70,000 miles on it. Ok here we go I live on top of a mountain and soon as i start up the mountain or any steep hill, or pull or tow something my service engine light pops on. First time it came on I took it to diesel shop they hooked it up to scanner and said it was code p1211 said icp sensor was bad so they put new one on. Couple days later light started popping back on so i decided to order a auto ingenuity after doing some research.
Hooked up to truck started up mountain while scanning at wot light pops on code p1211 and think it was live data I remember seeing icp pressure at 1922 and duty cycle at 63% i was trying to drive and read it at same time and my lap top went dead. What does this reading mean 1922 pressure/ at 63% cycle done little research but dont really understand. Year and half ago replaced all orings on all injectors, new rebuilt hpop pump. New ipr valve, glow plugs, past month 2 different icp sensor new,and new ipr valve new pig tails on both and light still popping on.
Ford 6.0L Power Stroke Diesel :: Long Crank / Idle For A Couple Minutes / Died And No Start
I need to get my oil cooler replaced but that's besides the fact. I drove it on a little trip the other night ran fine. Then went to start it after i was done with what i was doing turned it over didn't start the first time. Cycled the key and cranked it again. Started up drove it back home on the high way no spitting or sputters got off the high way it started idling like crap and shaking as i accelerated but made it home. Let it sit over night and day (was at work) got home to start it and it fired up no problem but still idled funny.
Revved it a couple times and it seemed to clear up so i took it around the block. Floored it and it ran like it was suppose to then go to the other side of the block floored it again and it had no power and sounded like it was running on 4 cylinders. Pulled it back in the driveway idled weird and cleared up again went down the street and floored it ran like a scaled ape and then just died. tried cranking it over and nothing finally got it to start after holding the ignition on ran and then died again. Got it pushed home and decided to fire again after a VERY long crank and it idled for a couple minutes very horrible and died on its own and hasn't started since.
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) :: F350 - Hard Start When Engine Cold
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.
Ford 7.3L Power Stroke (1999-2003) :: Cranks But Won't Start After HPOP Service
Removed and resealed HPOP and fuel bowl. Now she won't start. Ran fine before pump & bowl was serviced. I had leakage that I wanted to clear up. I have made no less than eight 15-20 sec start attempts with out even a cough. Reservoir is full, fuel in bowl and over 140 RPM when cranking.
AE info:
IPC duty cycle - rises to over 60% during cranking
IPC voltage - .18 all the time
IPC psi - 0 all the time
I did verify I placed the ball between the pump face and the "non serviceable" pin. I did leave out the spring and check valve seat from one of the output connectors. That has been corrected.

Yesterday my truck began to give me some problems starting. The engine turns over just a couple of times then it sounds like the starter disengages and winds up. it took multiple attempts but it finally fired up. Does this sound like the starter or could it possibly be the starter relay?

My 99 250, 7.3 is having some strange issues as of lately. When I start it in the morning, when the engine has fully cooled down, it starts right up, then it throws the "wait to start light" runs real rough and just shuts off. Run the glow plugs a few times, start it up and it will do the same thing for maximum 30 minutes, then all the sudden I start it and it runs fine. I've replaced the fuel pump, cleaned the fuel bowl, new fuel filter, I just don't know where my problem could be. It doesn't make sense. But once I get it running and it warms up, runs fine all day. Go to bed, wake up, has problems again.
View 14 RepliesFord 7.3L Power Stroke (1999-2003) :: Engine Stalls After Warming Up For 10 To 20 Minutes
I have a 2002 F250 7.3 4WD automatic with 313,000 miles. A week ago it started stalling after it idled for 10 minutes. It acted like it wasn't getting fuel. It would sputter a few times then just quit. I changed the fuel filter and the truck ran fine the rest of the day. Since that day, it has acted the same way every morning at 1st startup. It idles fine for 10-20 minutes (depending on how cold it is outside), then hesitates a little, then stops. After going through 3 new fuel filters (thinking I had bad fuel), I stopped putting in a new filter every morning, and found that if I just waited 4 or 5 minutes, it would start and run fine after that. It then runs fine the rest of the day.
After it stalls, it will not start right away. I need to wait a few minutes. I've tried draining the fuel filter bowl also. No luck. I tried a new Cam Positioning Sensor. It seems to be related to temperature. It's been getting down to 30 degrees Fahrenheit the past few mornings. It starts fine and idles fine until the temp gauge just starts to move. Then, the stall happens. My fill-up just prior to this happening was with B20 Bio Diesel. I suspected that for a while. But, I've ran all that fuel through plus 4 or 5 regular diesel tanks through, so I no longer think it was related to that. It do see the check engine light when it stalls. I had a shop read my codes and the only code was bad KAM memory. The mechanic said that code shows up all the time on these engines and not to worry about it.
Ford 7.3L Power Stroke (1999-2003) :: 2002 - Idled Rough After 2 Minutes Then Stalled Now Won't Start?
So I went out this morning to start the truck up like I do every morning. It cranked once, and didn't start, which is somewhat normal. second crank it started right up, which is normal, then after about 2 minutes, it seemed like the rpms were bouncing and the engine got a little more slower and louder, then it dipped below 500, then stalled. After that moment nothing. It just cranks. Now it was VERY low on fuel, I've been this low on fuel and never had anything like this happen, so my neighbor took me up to the station and I bought 2 gallons. came back, still nada. I went out after letting it sit on the block heater for about an hour and noticed a small puddle of fuel under the truck on the passenger side. I went to start it and the fuel gauge went up to a half tank. cranked, no start. then again and it went up again but slowly started creeping back down.
Now the kicker, I have very limited knowledge of diesel engines, or gas for that matter. So if my intuition is right, this is probably going to be a learning experience for me... what should I check first guys? Its plugged in right now but I am sure that's not gonna fix it.. I am gonna change the oil first since it needs it, I bought shell rotella triple t 15w40 which im assuming is ok. last winter It was leaking fuel when it was really cold out but that was it, just leaking a bit and then after spring it went away. I know I should have fixed it when it started but I have an extreme anxiety to letting any mechanic near my vehicles and just about as much anxiety trying to fix it myself. I'm at a loss for what to do, I'm a pro with computers but this truck scares the crap out of me, I'm terrified I'll do something worse.

Ford 7.3L Power Stroke (1999-2003) :: 2000 - Rough Shaking And Vibrating Start For About 5 Minutes?
I have a 2000 4x4 Limited 7.3 Powerstroke. 290k miles and runs like a top. However, if I don't plug it in for a few hours before starting she sounds like an old John Deere Poppin' Johnny. I had the glow plugs replaced yet had to go back to the repair shop three times since because it threw a code each time. No codes now just rough shaking and vibrating start for about 5min (without plugging in block heater) or so then once warmed up she runs great.
