7.3 POWERSTROKE P1211 FIX!!!

[@markrandall1456]

Nice job. I know the feeling of success on a lingering problem. Man when you get it right it’s such a lift off your shoulders. Congratulations on a job well done.

[@ydocproductions5593]

Thank you! There were countless hours spent reading through forums and phone calls trying to pinpoint this trucks issues. A lot of people took time out of their busy schedules to talk me though each system of the engine. It was worth it to see this one through to the end. Can’t begin to tell you how big of a weight has been lifted off my shoulders. Thanks for watching😀👍

[@metalartRestoration123]

That's a great feeling when u finally fix something u been working on for so long. Congrats on fixing your truck. One thing I would probably do is a oil change just to try and get some of that metal out.

[@ydocproductions5593]

I agree, just yesterday I did an oil change for good measure and should have a fairly simple maintenance schedule from here on out. It’s been really rewarding to see this truck fixed. I wish I fixed it sooner, but on a positive note I now know just about everything there is to know about these engines, so it’s been a great learning opportunity. Thank you for sticking with this project throughout the years😀👍

[@357magdad]

I'm glad all your work paid off!

[@ydocproductions5593]

Thanks Magdad! I was a long time coming but I couldn’t be happier. The truck works great now. Thanks for watching its great to hear from ya😀👍

[@danielchavez6826]

Glad to see that bad ass truck running rights. Tear the pump apart. I’m curious myself.

[@ydocproductions5593]

It runs so great now. I’m so happy with the truck! I’m tearing apart the pump hit a wall and don’t know how to disassemble the rest of the internals. If I can figure it out though I’ll definitely post the video👍.

[@packingbone1953]

Great video good job fixing the old girl!

[@ydocproductions5593]

Thank you! The truck runs so well now. Can’t believe it took this long to fix, but I sure did learn a lot. Now I can diagnose just about anything wrong with these old Powerstrokes, so it wasn’t all bad.

[@ronaldlemons2836]

My fuel pedal dont have a place for a throttle position sensor

[@AndrewBirrenkott]

When my HPOP went out it was a (Hot No Start). Truck would cool down and fire right up.

[@beantooth]

YES! Great work buddy, way to hang in there!

[@ydocproductions5593]

Thanks! Feels so great to have the truck fixed. It runs so great now!

[@mattbohac]

Nice! Glad the hpop worked for you as well!

[@ydocproductions5593]

Thank you! I couldn’t be happier with how well it runs now!

[@mattbohac]

Same here on my truck! Not sure if you remember when you were troubleshooting I was too with literally the same exact story as yours! Hpop had been replaced with a no brand one less than 2000 miles on it and that was the culprit! I commented to try and change hpop! (Easier said than done $$$) haha I replaced everything before the hpop haha. Once I replaced that I was in a whole new truck!

[@ydocproductions5593]

@@mattbohac Even though I wasn’t the one to put in that cheap HPOP it’s a great lesson learned that you usually get what you pay for when it comes to these precision parts. When I first bought the truck I would buy the cheapest sensor I could get my hands on for it, but as time went on and I learned more. When it comes to these engines best to stick to Motorcraft or an equivalent high quality part. Glad the truck is doing great for ya! Hope you have many more trouble free miles!!! (I certainly have enjoyed mine😁)

[@WallaceRoseVincent]

Cool! And I ain't ever gonna own a diesel 7.3 powerstroke!

[@ydocproductions5593]

Yup. You either like wrenching on these engines or ya don’t🤣

[@ronaldlemons2836]

2001,ladt year i changed the icp and the sensor that connects to the hpop, actually i replaced a lot of parts on this truck, i put a 40,000 volt idm i replaced the whole upper wiring harness tbe map sensor,the cam sensor

[@SwappedByMetro]

What symptoms were you having for the P1211 ?

[@ydocproductions5593]

Hi, I have a whole playlist of videos that go in-depth of what I was dealing with the p1211, but essentially I would loose power at around the 30-35mph mark. I could turn the truck off and restart the truck and it would act perfectly fine until you hit that mph mark again. Basically I had a bad mechanical fuel pump and HPOP that couldn’t keep up with the trucks’ demand under a load

[@GamePrepper]

Did you fix the had shift? I’ve watched all the videos up to this point and I don’t recall if you fixed it.

[@ydocproductions5593]

Yup the icp sensor wasn’t plugged in causing the transmission to shift hard. It turned out to be the mechanical fuel pump and the HPOP. Everything on the truck runs great now👍

[@carveriorg7127]

That was exactly my reaction when I replaced my hpop to fix the p1211😂

[@ydocproductions5593]

That was the most authentic reaction I’ve had on the channel🤣. Sure was worth the hassle of diagnosing each system of the engine. It was only a matter of time before I fixed it😂

[@fuelup7504]

I’m at the same place in my 02 wen I put tuner on it I started to get the 1211 and it my hpop I’m watch the press drop off at wot I’m watch the date in my edge cts2

[@ydocproductions5593]

Ya tuners have been known to cause the p1211 code simply because they demand more oil than the system can give. How many miles does the truck have? Have you considered injector orings as being an issue?

[@ronaldlemons2836]

Evenin I forgot to mention that while i was doin all the changes i did the fuel tank mod,i took the 2 filters out and installed a new pickup foot and changed the tubing in it and added a external filter mounted on the frame annnd installed a new OEM fuel pump,im just worried its the hpop. Truck has 209k miles. Thanks for all your input, i thot about replacing the ipr and icp even though they are only 8 months old.

[@ydocproductions5593]

If you replaced the icp/ipr sensors with Motorcraft parts odds are they are just fine. I replaced those parts or were recently replaced by the previous owner on my truck so I know exactly how you feel. I came to the same conclusion that if everything major on the truck has been replaced then whatever’s left must be the problem. HPOPs’ aren’t cheap so it’s good you replaced the cheap stuff before spending big bucks. I would try one last test if you’re willing. Grab yourself a Hydraulic hose that’s capable of holding over 3,000psi with a 4-5,000psi oil filled gauge, and hook it up to an oil port on the head and get a reading of oil pressure driving down the road. I don’t know how many videos of my truck you watched but on my powerstroke I “dead headed” my HPOP in the driveway and gave me perfect readings. That would all change when driving under a load however. Turns out when I took my HPOP apart in one of my videos there was brass shavings all over inside the pump. I say that to say, you could test the pump in your driveway and it act completely fine but when you demand more oil pressure and that oil gets hot thinning out is when the pump can’t keep up with the demand that the injectors need. But taking some time, doing some tests, and getting some solid numbers will help you make a decision on whether you even need to touch the HPOP or not. Does the vehicle have a tuner/chip on it? Also do you have access to an OBD2 reader like “Forscan” (about $30) that program can give you live readouts of your ICP and IPR pressures so you can compare it to factory specs.

[@ronaldlemons2836]

I installed a bully dog tuner last year but mainly drive it in stock. i prolly need to backtrack and say that after i installed the new pcm the truck absolutely ran so good but... something strange would happen,when io would take off normal at about 20 mph its like the turbo would kick in and the truck would just accelerate it was kinda strange and 2 weeks ago i went to the car wash and when i got ready to leave the truck just would barely go and it had idled the whole time in the wash bay,and yes i orded a forscan unit that plug into my laptop and thats where i got the codes,it had a P1249,P1209,P1212 and a P1211,i havent checked the fuel pressure i do have the gauge for it.

[@ydocproductions5593]

@@ronaldlemons2836 Very interesting. Well if you said you replaced the pcm and wiring harness already, odds of having a weird electrical gremlin would be rare. It would make sense your HPOP could be faulty cause the p1209, p1211, p1212 are all ICP pressure related. I know you said you keep the tuner in stock form, but as you know when you put tuners on the vehicle it increases the demand for more oil pressure from your pump which could be a contributing factor. I would get a live readout with your Forscan tool of the ICP pressure and IPR percentage. Then get an accurate high pressure oil reading using a high pressure Hydraulic hose we talked about earlier, and see how much pressure your pump can physically put out while driving. It sounds like you’ve loaded the parts cannon and thrown everything including the kitchen sink at this truck. Before you buy a HPOP which is one of the most expensive single parts on the entire truck I think you should arm yourself with as much data and numbers possible before throwing more money at it. Have you replaced the injector orings recently?

[@ronaldlemons2836]

I have another question about the 3000lb hose and gauge, how do i see the gauge if im driving down the road? do i get a long braided hose and display it outside the hood?

[@ronaldlemons2836]

what is the part number of the bosch hpop you bought and will it work for the 01 7.3?

[@bloodsweatmoney9089]

Where did you order your hpop at? My truck will idle fine all day. But head down the road and maybe a half mile cel comes on and truck barely runs now. Turn the truck off then back on. Runs fine for another 1/4 mile

[@ydocproductions5593]

I got my HPOP from “RiffRaff Diesel”. Their a business located in south Oregon. I was EXTREMELY pleased with their business. Not only was the HPOP a great price, but whenever I had a question about installing it I could call up their customer service and they had every answer I needed. Because I live in the northwest it also arrived at my door in only a few days (the pump was really packaged well too). I’m not sponsored by them in anyway. Just a super happy customer👍. Good luck with your truck. A little advice before you buy a HPOP, might be worth doing some diagnostic work and testing before you buy a pump. Hope it works out for ya😀👍

[@bloodsweatmoney9089]

@@ydocproductions5593 thanks I'm not sure what else to try but this is the original pump in the truck figured it'll be better to just replace it. I thought it was a fuel issue but replaced my pump yesterday. But another thing is it was running fine then it would just lose power but now it's really bad.

[@bloodsweatmoney9089]

​@@ydocproductions5593 well I fixed it. I put a new ipr in after I did that truck wouldn't crank but I had bought a pigtail while at oriellys getting the ipr and pulled the wire loom off the pigtail and the wires were bare.

Its gettin frustrating ive replaced all the sensors icp,cps,ipr the exhaust sensor

[@ydocproductions5593]

Sounds like your so close Ronald. The throttle position sensor (tps) sounds like it’s faulty. I know it’s just one more thing to buy, but it sounds like you found the issue. Think you’re gonna have one heck of a truck when it’s fixed👍

[@ronaldlemons2836]

I replaced the pcm,the icp and ipr were genuine ford and the cam sensor. What causes over boost ?

[@ydocproductions5593]

The overboost problem could be because your wastegate on the turbo is faulty somehow. Depending on how many miles the truck has I wouldn’t dive into the turbo just yet. Well, it sounds like you’ve replaced every sensor that’s known to fail on these engines. That being said I would get a fuel pressure guage on the vehicle and see what your fuel pressure is (!!!UNDER A LOAD!!!). You want to check it under a load because you need to see what the fuel pressure reads under real world conditions. It’s a little bit of a hassle to duct tape a fuel pressure gauge to the windshield while driving, but important to get accurate readings. Another problem could be the in the fuel tank. Because the fuel tank is plastic on Super Duty’s, over the years diesel fuel will deteriorate the plastic and the “in tank” fuel filters could’ve gotten clogged up with that plastic. Also check the fuel pressure regulator off the side of the fuel filter housing in the valley of the engine for any restrictions. The point I’m trying to make with all of this is you’ve got to get a basis of what your fuel pressure is and to see if you’re getting a restriction anywhere. These trucks do weird stuff when they aren’t getting enough fuel pressure, and then send some random “overboost” check code when in reality it’s just a fuel pressure issue that needs to be straightened out. Again I hope this makes sense and is of some help to you. When I was having a hard time wrenching on my truck I went to a website that I’ll link below that really helped. They have all the data you’d need to compare to your truck, and hopefully help you spot any abnormalities. If there’s anything else I can do to help please let me know. www.oregonfuelinjection.com/content/uploads/2016/08/ford-7.3-94-03-diagnostic.pdf

[@bradleyfarve]

A hot tune will make that code. Nothing wrong but will defuel. I bought a boost fooler and now the truck doesn’t defuel or throw code.

[@ronaldlemons2836]

Your last you had a p1211 code, did you ever fix it? I have the same code and a 1212 and 1249

[@ydocproductions5593]

Hi Ronald, I did fix the truck with a new HPOP and Mechanical fuel pump. The truck runs so great now and is a joy to drive. With your truck p1212 indicates a ICP sensor error code and 1249 is when the pcm has discovered an “overboost” situation. Do you have any modifications to the truck what year of the 7.3 is it? If it has an overboost code that would probably indicate it’s in a Super Duty?

[@johnfitch9710]

I am getting the same codes. Did you figure out your codes? Thanks

[@ronaldlemons2836]

@@johnfitch9710 yes i did, but i went the long way around, i threw money at it instead of testing everything,i even pulled the PCM and IDM and sent them out for testing which came back just fine,i ended up testing my hpop which was a reman and it was bad so i pulled it and they sent me a new one, so as of today the truck has new hpop,new injectors,IPR,ICP,new upper wiring harness.

[@Sinister12v]

It's a remanufactured pump btw. You cannot buy a brand new 7.3 HPOP, they don't exist sadly. For what you spent on it you could have had a 20* from CNC and some money back in your pocket. If you're staying with those injectors though you wouldn't need it.

[@ydocproductions5593]

They’re the stock injectors so I didn’t need a 20*. It’s run great ever since I replaced those parts and am so happy with the truck

Im well experienced in these snd it commong for low pressure fuel issues to cause the hp oil side p1211.. its one of the first pp test steps in ford manual to check fuel pressure ect..

[@ydocproductions5593]

Hi Travis, I completely understand where you’re coming from, and truth be told I asked myself the exact same question. That being said my latest video I completely tear down the old HPOP that was in the truck, and it was pretty evident that something went catastrophically wrong inside. (In fact if you have the time I’d sure appreciate you watch the video to get your opinion on the matter) I think the damaged HPOP paired with the worn out mechanical fuel pump was a perfect cocktail of issues on why it wasn’t working right.
