The longer I own my 7.3 the more I realize that for slow diagnostics it's either throw a bunch of parts at it or for quick diagnostics get a scan tool that has a graph on it like yours. It might cost a few bucks but in the long run will save the savy back yard mechanic a lot of time and money in fixing the 7.3 and other vehicles. Ironically unless it's a really deep problem or intermittent most of the time the savy mechanic whose familiar with the 7.3 can diagnose and fix it just by listening to it and doing some tests with a meter. Thanks for sharing. I really enjoy your videos. Best Wishes & Blessings. Keith Noneya
Finally, real technical video without all the music and opinion. . It is nice to see information that is accurate . I am working on a 7.3 with over 400k . Its mine and has been taken care of . Already replaced the lift pump , filter, drain o rings and return lines. I think this is going to be my solution. I drove it to where it sits , and never could get it started again. It was for the better . I broke down in my travels and the repair facility that replaced the high pressure lines broke the air box, and caused a lot of damage to filter housing and surrounding parts. . It is disappointing to know that some parts changers have no respect for people who are just old mechanics and have to depend on others to get the job done. Thanks for the video. My scanner was stolen , But I have it down to the IPR or the cam sensor.
Thanks so much for the A1 positive feed back!
Love 7.3 L So easy to work on compared to newer diesels. Thanks for the great video. I would love to see some videos on when u have white smoke and what the factors could be and how to diagnose them
Thanks very much for sharing this diagnosis and fix. I'm getting the exact same symptoms with my early 99 7.3 but worse (with no pcm trouble codes just using Torque) to the point where it just stutters like it wants to start and doesn't idle. The only difference with the truck you showed here is that, while rolling with the starter, my IPR duty cycle is hitting 65% (and pressure to 3000+ within a few seconds) so I'm suspecting the IPR valve itself is sticking or a fuel problem. This video helps me narrow it down. Thanks again!
U BET!
Ian Malleua did changing your ipr fix your problem have same problem as you do thanks in advanced
@@omartorres6889 It helped a bit but did not totally fix the problem. The ipr I had on was definitely not sensing the correct pressure but at the same time (quite a coincidence..), some of my injectors came loose and scrubbed/smashed their o-rings.. I decided to bite the bullet, change all injectors (old ones had over 200k miles on them anyways) as well as put on a Riffraff fuel xover removing the restrictors that the idiotic Ford engineers put on (fuel bowl and the ones feeding each fuel rail) which starves the injectors.. I also put a Riffraff billet compressor wheel (I'm now seeing 15lbs above atmos/barometer vs 8lbs with the original garrett wheel) and now it's running like a top and puts out alot more power. I was surprised at the increase in torque just with these mods without chipping.. Thanks for asking.
Thanks for the information I'm a diesel truck mechanic and have a 5.9 Cummins 93 model but I'm thinking of getting a king ranch 250 older model 06 or 08 so you're part of my schooling in giving myself you explain everything just like I do to new mechanics I have tried to put videos on u tube my self but did not go well buy working on it anyway I'll keep watching thanks again this is Juan from San Antonio TX
Thanks pal...!! STAY AWAY FROM 08-10!!!!
I remember when the first 7.3 Powerstrokes came out. We had 2 new tow trucks and they would run like crap and sounded like that one. The Ford dealer was scratching their heads. I was talking to a tech in an International shop and he said they had an anti foaming additive they added to the oil to cure the problem in their trucks.
I started to pour it in with the engine running and before it was all in the idle smoothed out and the knocking went away.
A few days after the dealer said there was a TSB to use only use a certain Motorcraft oil in them. All the oil brands caught up quickly with more anti foam additives..
Nice
HEUI's cousin is a butter churn. Caterpillar and Shell (Rotella) worked together on that problem. When they came out that was about the only oil that would work.
I want to say this. As a Norwegian bound to drive vehicles from before 2008 (when Ford Norge stopped US import of SD serie due to import taxes - a new F serie with full spec would be $200.000,.-today) we are bound to drive old vehicles, import the parts and turn wrenches ouerselves. Due to this and other factors - I have to have my car going for at least another 13 years - praying my then 32 year old car will fight to the end. I'm not alone - as there are plp that like and have greate use of vehicles like Super Duty's and Excursion and most of us use greate videos like this to keep our older vehicles going. There is a bunch of plp that does not have the finances nor the ability to purchase newer cars - thank you for not just post content in regards of newer vehicles and problems/solutions related to them.

Anytime pal!!!!!
thanks for the video! really helped me out. i watched a couple other videos on this IPR replacement as well and you can also use a 1 3/32 socket to knock the IPR loose which you can purchase from Harbor Freight in a Shower Valve Socket Wrench Kit... attached an adjustable wrench to it and then gave it a smack with a hammer since my IPR was in there pretty tight as well... not the funnest job to do but beats paying a dealership. thanks again!
Thanks pal
Greetings ARod
I have a 2000 (Aug 1999) F-250 7.3 L. Thank you for the video. Expensive part. With the employee discount, it was over $250. I did pretty much what you did. Thanks for the details about how it works. Much appreciated.
They sell OEM Motorcraft IPR's on EBAY for 169$, sorry buddy but you kinda got stiffed.
Thank you. tons of good info. Just bought a 97 F350 7.3L (188,000 miles) yesterday. was on a flat bed tow truck after 25 miles. bought it running on rear tank. Filled both tanks, switched to front, 10.3 miles later it stalled out. Cleaned mud out of the bowl, tried to clean filter (on side of highway), had fuel filling the bowl but no start. I'm just looking into the culprit.. Thanks for a great vid.
Thanks for your kind words, best of luck to ya👍

Finally a video on the legendary 7.3 . . . Ha ha good video thanks powerstroke tech talk
No prob, glad u came back to visit.
THANKS FOR THIS IM A NEW 7.3 OWNER ON "BEER MONEY" WALLET. I LEARNED A CRAP LOAD. THANKS. I JUST FOUND YOUR VIDEOS.
Thanks so much for stoppin by. Check out my channel, I have a lot of great content to watch

This was just what I needed On my e350 van I could not find the improved valve. Quite buried under fire wall. A hard reach but thanks to your video I found it.
Hell yea
Thanks nice video... i am still running my 2000 7.3. 435k. 9 oil changes 18 oil filters. Oil sampled by independent lab. Never can back out of spec.
Thanks my 02 f250 with the 7.3 was doing the same thing changed it and is working perfect. Good video helped alot
Sweet man thanks so much for watching
PowerStroke Tech Talk w/ARod 7.399 won’t idle
Ok...
Oh thank god... until 40 seconds or so I thought I’d selected a video from the Powerstroke Techno Music channel by mistake!
Hardly any miles on the clock, and for a 7.3 yet, guys would be tripping all over themselves for a low mile 7.3. Sounds a lot better now after the IPR swap, and yeah not much for PID's but some is better than none. Looks like you got this one solved and in the bag nice work as usual man, keep them videos coming from that secret location...lol
Thanks 4 comin back mista Demon
Made my day! I was ready (not really) for a rear main seal replacement. Thank You!
My 7.3 2002 fuel mileage started dropping into the 7-8 mpg range city driving. Bought a new IPR but couldn’t get the old one out, working on that lol. Tested the old coil and was getting 33.9 ohms, tested the new one and was getting 9.3 ohms. Threw the new coil on the old IPR with 229k miles on it. Reconnected the wiring connections. On start up engine knock was gone when cold and idle was Super smooth. HUGE difference. I do have oil in the valley so I’m thinking the seals on the IPR are failing so full replacement as soon as I get the IPR socket I need.
I wish i would have seen this a while back(2019) i know it was not out. My buddy's 1999 F250 7.3 same problem but i didn't know enough about Diesels. Been working on cars on the side since i was 15, 63 now Thanks
You nailed it for me! I was all over the map as to what the problem was. Thanks so much. Keep it up!
An '02 with low miles being referred to as 'an old 7.3?" I don't think so! That's rather why we have 7.3 is the longevity. I'd love to get my hands on that! Mine is running 300k miles and I figure it just got broken in.
Ha👍
Man! Thanks for this video! Super informative and helpful! Deff going to watch more of your channel
Thanks for watchin, stoppin by & keepin it positive. Much appreciated! See you on Fridays 8:45 pm EST!!😉👌👍👊
i dreaded having to do that for 8 years. glad i didn't have to change mine out. still a good video
Yes indeed I am on my way home to the hole. Thanks for posting do more 7 3 and 6 7 vids
Excellent video for this newbee 7.3 diesel fan!
Luv the Happy Gilmore

Thanks for a great vid! I'm on my third 7.3, currently 2000 F250 with 230K miles. I have been trying to run down a problem with rough idle, I did have three codes, all sensors, all clean now. After replacing glow plugs because of hard cold start, inspecting wiring harness, putting her all back together I have a p1316 and p0603 code. Another problem to deal with. But the bad idle and loud engine might just be that IPR, or hpop. Will investigate further and thanks again.
Bought an 03 7.3 long bed crew RWD with 155k on it for 7k last year... Seems to run great for the first 5k I put on it. did I get a good deal?
So far have changed the fuel
Filter and oil and filter. Used a 9691 filter to hopefully keep the oil extra clean. Bought a drain valve to make oil changes super easy and not have an excuse to put them off.
Watching all the videos I can find on maintaining it and your channel has lots of helpful stuff. Thank you!
Only issues I’ve had so far are a stuck rear caliper (good excuse to pump out the reservoir and vaccum bleed fresh clean fluid through everything but the ABS unit. Used about 4 quarts of DOT 4 fluid to “wash it all through”
Other issue I am dealing with is a “rough bearing” noise that seems to be from the rear end, and needing new clutch packs, or more friction modifier in the diff.
Hoping it is a wheel/hub bearing in the diff, but thanks to videos like yours, I am confident I can tackle it all myself, with a few special tools.
Thanks for all you do for the education of powestroke owners and the people who work on them!
Thanks for stopping h and being positive on my channel, i really appreciate it. I wld check your driveshaft center bearing...have had lots of them growl like a bad bearing. Yes seems like a good deal to me
PowerStroke Tech Talk w/ARod - thanks! Every video I saw on the center drive line bearing showed what they sound like when WAY farther gone than this one is... with the drive shaft flopping around and clunking horribly.
After the brake work (and tightening the front wheel bearing spindle nuts to the 18in lb spec, which reduced some seemingly excessive play in them) I gave it a quick test on jack stands, but didn’t have time to get underneath and use a “mechanic’s stethoscope” to localize the rear end noise source. Will check that center hangar bearing first, as I would love for it to be that, and not a wheel bearing.
Do you have any videos on the ford/sterling 10.25/10.5 clutch pack replacement or other differential service procedures?
Found enough to confidently do wheel bearings in the rear hubs of that turns out to be the source of my noise.
One other Q... my diff is hard to turn, and the wheel on the other side travels in the opposite direction... some videos I have seen indicated the LSD’s opposite wheel should turn the same direction, and didn’t say anything about it being hard to turn/taking significant effort.
Is this an indication of failed clutch packs?
It doesn’t feel “rough” per say... just tough to turn, even holding the wheel.
thank you, great video, great refresher.
Check out my new video I just did
Nice upload, having that dang computer has to be helpful, other then the tried and true swap it till it runs w/o knocking, or what ever other symptom may be present, but now I know if I hear knockin it could be IPR or any of the other zillion sensors! Im refreshing myself on the PSD as I just bought another in a 96 F350 4x4 box truck.. Glad I still have my 7.3 IDI though.
Friggin rights bud
that video was pretty detailed thank you for sharing and im going to the store to get a 29milli before i start
🤣😅😂👍👍
Brillant! Thats why they pay you!! great vid!
Thanks so much, see ya nxt week 😎
thanks for the video.. straightforward. will do mine as soon as it arrives.
Thank you for by & keepin' it 💯, good luck
I LIKE IT ! WATCH YOUR VIDEOS MAKE ME FEEL LIKE A BETTER MECHANIC !
Thanks buddy!!
Amazing... I'm going to change my IPR on my 2000 7.3 ..I'll get back to you.
Excellent description and how to. I am guessing the scan and laptop computer software is a dealer only item?
Thanks for posting.
Eric
No prob, yea it is...
Great video. Could the loose stamped nut on the end of the valve stem potentialy have been a problem?
Yes sirrrrrrrrr my truck I checked it and was lose I tightened and works perfect so I have the new one here just because you never know
I had a no start 7.3 i diagnosed to failed ipr. Replaced and first time i let off throttle on road test it stalled again. Had it towed to shop and found new ipr was full of metal flakes. Called customer to inform thinking it was failing bearings and found out they put in 2 cans of engine restore. Never put engine restore in anything except a garbage bin.
Ughhh what gooofs
Thanks for the video....it’s interesting to look back at a 7.3. Also, I can confidently say Arod and Powerstroke are both American....China they are not.
Lol thanks for watchin bud
Awesome Video, I am having the same issues. Please Please Please tell me what are the specs of your OBD 2 Reader. I want to get exactly the setup you have going on here!
Email me my man! Look on my channel
ARod, I have a 2000 F350 with the 7.3L. Haven't had to do the IPR yet, but did the ICP. I'm curious: as a professional at this stuff, would you say that the 7.3L parts are becoming harder to come by? To me it seems not, but I know a guy who has a 6.0 who swears up-n-down that they are and that I should "upgrade" to a 6.0. Not something I'm that interested in really, I like my 7.3L. And hell the 6.0 isn't that much newer. Anyway, any feedback is appreciated. Thanks
7.3 parts ALLLL day long guys. Nuts and bolts yea but the meat and potatoes no..
Very Informative video thanks ...
Very good inf. Nice video I learned something new today yyyaaauuu🙏

Thanks!
There’s a hex nut on top of the oil tank for the hpop you can drain it with a hand pump .
awesome video simple basic information good dude working on it thank you, got the DUB
My second reply here, Still trying to chase a problem down, now armed with OBO11 scanner. After install new IPR ran a lot better, but still was giving me problems, now is back to where it was, I may have made the mistake of buying a cheap IPR off Amazon, not sure where it was made but it did seem to have a finger print and smelled like soy sauce? So I have purchased a genuine 100% Motortcraft,, twice the cost and I'm sure it's probably not made in the good old USA, but I have read a few threads that it's best to buy OEM. I've been doing to shot gun approach try to avoid the stealership ( sorry ). I took it in for free scan at my local dealer. I thought free I should at least have the oil change, as I usually do it myself. Got the truck back same problem. The paper work indicated they test drove didn't notice any problems other than air filter was dirty, well I had just cleaned and oiled it, it's an S&B. How could a mechanic not notice a truck that shifts into 4th gear starts shaking, making loud cackling sounds, and the boost drop to zero, along with surging idle? So back to square one, will try the new IPR. If any one is still interested in my story. I have done buzz test, all sound the same, taken valve covers off, checked all wiring VIA OVM, put new glow plugs in as it would not cold start, now does, put a wicked wheel 11 in the turbo, no improvement over stock and same problem, changed every sensor that coded when I got the truck. Throws no codes. Fuel pressure 50 idle and WOT, Hpop 600 at idle 2900 plus at WOT, within it's duty cycle %, new fuel filter. Leak tested the turbo system, found a couple of small leaks at boots. Checked all wiring on harnesses. No smoke, no oil burn or leaks at all. If IPC doesn't help, then shot gun it again with IDM, PCM. Oh also checked vacuum lines. I make 23lbs of boost if it's WOT. Could I have a EBVP valve stuck closed or partially? Will check that also as the boost drops off so severally.
Homie ARod killin the 7.3 IPR game. Another killer video bro. I learn something every day.
Thanks for watchin my content ol GQ Tavo24vv
PowerStroke Tech Talk w/ARod lmfaooo I wish I could double like that comment 😂😂😂
I believe the IPR valve is going to be my problem. I have a 02 7.3. I put in a new IPC valve and checked on my crank position sensor.. Seems to be working.... I put new glow plugs in new glow plug relay everything's turning on the truck acts like it's trying to start but doesn't..... It was hard starting when not plugged in..
When I plug it in it would start fine and have a little Miss till it cleared up.. Now it's plugged in does not want to start ...
If youd like to help support my channel with a donation we can dive into your concern
🤦♂️ Not my IPR valve! I need injections..😭😭
THE Best narrative I have heard for any 7.3L. “no more knocky knocky” 👍👍
Thanks so much buddy
I have a 2001 7.3 with 150k , it's been a great truck . Only issue I've had with the engine is a loose plug under the L valve cover.
Recently it threw a p1211 code while pulling my camper. I use a bully dog just for gauges. It has a 6 position chip which works great.
I got just a hesitation in power . I shut it off and restarted and no eng light . I've drove it a hundred miles since with no more issue.
The truck is very well maintained it also has the hutch mod. and a spin on filter before the elec fuel pump. This is a rust free truck so I never plan on getting rid of it.
Any suggestions , on the 1 time issue . Thanks
Sounds like id be checkin FP under load & see if it drops....
mine got same noise on start up will replace i p r this week thank you.
You're videos are great and really helpful. I just bought a 01 f250 7.3 and going through and replacing some of the problem areas and came across a bare braided wire in the main engine harness that runs between the valve covers, going towards the driver's side before the injector flow plug connector the braided wire just stops and has no where to go? Just wondering if this is supposed to be a ground and if so where does it supposed to ground to? Any response is greatly appreciated.
Id have to see a picture broski...

If the ipr valve is going can it also cause the truck to completely shut off when it’s hot than once cool will start. After some research I can only guess that the ipr is failing and losing all fuel to the injectors
Si
Sounds like cam sensor.
recently had one kick my ass for a little bit. complaint dies intermittently can let it sit for a while and it fires up and may not do it for a few days, no codes of course. i get it look at the cps see its been in there for a long time replace it test drive 50 miles no issues at all. customer shows up to get his truck drives home makes it 2 miles dies out no restart like maybe a high pressure oil leak, but while i did the test drive i watched duty cylcle on ipr and it never went above 35% so i know no leaks, well when it was dead on the road the ipr % was 65 and making 100 psi hp oil. i swap it out with a known good one good to go until new on came in. i guess the spool inside or the coil was at fault.
Ive been bit be4 like that too
Great job, thanks
Love the video I have ordered a IPR and am going to put it on as soon as I get it . I have a starting problem that just started . It won't start my son told me to shoot some starting fluid in the air intake and it cranked and ran great. Let it run for about 10 mins ,cut it off and restarted it. I hope that fixes it.

Very helpful, thanks
Great video.. I have a question.. I removed my fuel bowl and HPOP due to oil leak , replaced all seals and reinstalled. She took about 30 seconds of cranking to fire off on the initial firing, I let her run for about a half hour while cleaning up. But now when I shut her down and let her sit she take around 10 to 20 revolutions to fire back up.. once running and I shut her of and then immediately fire back up she fires right away. But if I let her sit, shes back to 10 to 20 cranks... any thoughts .. thanks Mike

great video. i appreciate the information. i just hope i can fiquire my 96 stroker out
I think I might have the same problem on my 2000 f450.. do I need to get the part from the dealer… or anything from Autozone would work?? I heard is best to use them from the dealer!!
My 02 7.3 shut off driving down the interstate at 80mph with zero warning. I made it to the shoulder and it would crank strong but not even try to start. Got a tow home and when I pulled off the trailer it started right up. I suspect the IPR valve and that is how I found you.
I have had another problem that I have no idea on. For the last 2-3 years I get a very loud sucking sound when pulling a trailer uphill and now I get it even without a trailer. It goes away when I down shift and the rpms come back up. It is incredibly disappointing to have a 7.3 but feel like I am towing with an old v8
Probably your cam sensor. The other probably and exhaust back pressure control solenoid under turbo in the turbo pedestal...
@@PowerStrokeTechTalkwARod Thank you for the response. I will start studying those two things.

Did you have to add oil to the hpop when you put the new plug back in?
No
What PC program are you using on your laptop 🤔
IDS
Thanks 😁
What goes bad on the IPR? Is it just the solenoid reason I ask is I don’t have a long enough socket and was wondering if just changing the solenoid would be okay?
What type of socket did you end up using?
thanks, you make it look soooo easy, im going to try to do mine today.
No prob my dude!
After losing some oil in the hpop does it need to be topped off? Just did this thanks to your video, awesome help!
Hpop is constantly supplied from low pressure lubrication pump. It’ll refill in a second
Hey man, I always watch your videos, thank you for taking the time to make them. I have a 7.3 that I’m not 100% on. It’s a long crank and the easiest way to describe it would be an old car with a carb and it’s been sitting awhile. It’s a long crank and when it finally starts it sounds like it’s starving for fuel for a second then idles like normal. The ipr hits almost 60% when it finally starts and it lacks power. It maxes out going up a hill at 65%. I thought try a known good ipr and no difference. I’m thinking possibly a pump. On a test drive today it hit 65% at idle and hit the throttle a few times and down to 30%. Any ideas or suggestions? Would these symptoms lead you to think injector o-rings? Oh btw it has good fuel pressure at idle and under full throttle, throws the p1211 code for icp pressure. The sensor is fine with .25v and 0psi koeo. The truck has 331,000 miles on it
Gimmie ur email
I have a '99 Super Duty with a 7.3 and my oil pressure gauge on the dash always reads a little low. Do you think I have a bad IPR too? I kept adding oil but the gauge never read higher. I stopped after adding 7 quarts because it got hard to start and kept smoking when I revved it. Are the IPR valves you have in China better than the ones in the US?
Ur IPR valve has no relation to the gauge on the ole dash. Yes the ones from Bangladesh are the most cost effective as a replacement
Thanks bro. That was what i needed
Great
I think that my problem with my 7.3. It misfire right before it starts up. When it's cold,. But after it warms up. Starts the way it should,,. Thanks
I'm debating on buying a 2000-2001 7.3 powerstroke diesel E350 with 227,000 miles for $1,000 and was part of a furniture installation/moving business that was said to be fleet maintained for awhile then taken over by the business personnel to keep up with it. It has been parked since May 2019 and it doesn't show a wait to start (glow plug light) and supposedly it would run then cut out.. but if the glow plug light doesn't illuminate now how would it run prior... I could use some pointers to help me figure out this issue. I've heard about all of the parts with the pcm, ipr etc.. it seems like a bit much for my first 7.3 psd diesel to take on but I know these are legendary engines and would like to pursue it if it's not too much work that it'll cost more than what it's worth. Please help thanks

I have '01 F350 7.3 with 416,000 mi on it......still running!
very nice video . Thank you ..
Nice video! One question. I have an 01 7.3. I replaced my ipr and icp with genuine Ford parts. When I replaced my ipr I found my hpop reservoir was empty. I put the new ipr in. Filled the reservoir up. Started right up. Runs great. Turn it off and within a few minutes the hpop reservoir drains down. It will crank and start after about 8 seconds of cranking (as the lpop refills the hpop reservoir ). Once started it runs and pulls as it should. I checked the short circuit check ball in the block. It appeared to be fine. I believe something in the hpop is letting the reservoir bleed down the oil back the oil pan. Do you agree I should replace my hpop ? I resealed the hpop last year and never have had any problems. It lost the oil in the reservoir last week on a 12 hour drive. When I stopped to fuel up and it took the long cranking. I continued my trip and thought maybe the ipr was the issue. Once started my ford dealer cannot find any problems. Only that the reservoir is bleeding down. They think it’s the lpop or the hpop. I think hpop because the lpop refills the reservoir and has pressure fast. I hope you might could shed some light on my Situation.
Great question, i have had 1 where it was the HPOP, the other had a flattened gasket in the reservoir which was allowing all that primed oil to bleed right back to the crankcase. You could take the top section of the reservoir off and inspect.
PowerStroke Tech Talk w/ARod Wow! Thanks for the fast response! I did remove the cover of the hpop reservoir and look inside and slightly lifted it. It looked ok and wasn’t leaking on the outside. (I didn’t have a replacement gasket) so I was careful to tighten everything back down. I was thinking about when I replace my hpop I would get new gasket and seals for the reservoir also.
Sounds like what i would do! Good job
When my IPR started failing the truck would start and run fine when cold or hot, but if I parked for 30 minutes to an hour it wouldn't start again until it cooled off for a couple of hours.
Werd
Rusty Hathaway same issue I’m having
I've got a 2000 F250 that won't start. 104k miles. It has oil in it. The Wait to Start light comes on. When I crank it, it sounds like it's turning over fast enough but the tach only registers about 50 RPM. There is some white smoke out of the exhaust when cranking.
Where are you located ARod?
I am in the state that looks like a mitten
-- that must be mitten-gan
Hahahahahahahahahahahahahahah
Should the tach read more than about 50 RPM when cranking?
Also the connection to the ICP is not oily.
I wld say yes, 150 180 200 ish i wld expect...
I have a '96 7.3 Powerstroke that starts fine, but lopes when started warm until you idle up for a couple seconds. I have replaced the icp and ipr with no improvement. What should I look for next?
Many thanks for all the good info you give us!
I wonder if your turbo pedestal exhaust valve is chokin it off
@@PowerStrokeTechTalkwARod Thanks for the fast reply!
Do I need to pull the turbo and clean it?
It runs fine after you calm the idle and starts easy.
Might wanna see if it moves freely....there is a spring inside the pedestal that should be quickly pulling it back
@@PowerStrokeTechTalkwARod I will check that. Thanks for all the help!
@Arod at 3v05 when you fire it up, have you started it and tried hitting the accelerator at all when its idling rough like that? I have an e99 all stock (to my knowledge) and I have damn near the same idle situation however it's not knockin hard like that. I've replaced the icp sensor with an oem motorcraft one. Fresh oil and filter. New oem fuel filter. I'm chasing an issue. I'm not a mechanic, but I'm reading as much as possible and trying to get well informed as I attempt to diagnose and fix. If you have any advice please help. I had an 01 with 380k on it before and no issues. This e99 only has 180k on it but I'm assuming it's been somewhat abused in a commercial fleet that didnt know how to maintain or operate these old dinosaurs properly. Thanks in advance.
At 3:05*
Forgot to add to the story.. it will run rough like that until I run her a bit harder goin thru the gears and really gettin the turbo to spool up. Almost seems like it has a clog or some kinda restriction goin on and then all the sudden let's loose.
Sounds like you need injectors. When they are cold they stick. As engine oil temp goes up the power starts to come back. Not maintaining the oil will make your concern happen
@@PowerStrokeTechTalkwARod if I get it to a shop and have them run the key on engine off injector test would that be sufficient enough evidence to determine that for sure? I'm really hoping that's not the case but really wouldn't suprise me. I bought the truck cause its rust free. The longer I have it the more I find that needs fixed.. it sucks bein willing to try and fix one of these fuckers but itll be worth the money if my wife dont kill me first haha
No that wont, that just tests the electrical portion. The issue is with the mechnical side, the portion that has oil running thru it. U need 2 pull all 8 and have them bench tested!
Great!! & Love from China!!!!!!! 😂
New subscriber, nice vids bud 👍🏼
Thanks, stay and get comfy!!
Hi , I have a 7.3 excursion. No start low icp. It will start on 4 cylinders. That's w pass side deadheaded. I've done inj orings. Icp,ipr valves. Thinking I had a bad poopet vavle I replaced ps injectors. Still no start low icp. No codes until 20 seconds into cranking. Can you offer any advise?
Whats ur email...?
Its barry$thompson$1204@yahoo.com
Minus the $
Good video arod I was wondering what the duty cycle value means on the IPR such as is 10% does it mean it’s open 10 percent or something else
Yep
Duty cycle means “proportion of time something is, or can be, in the “ON” or, in the case of the IPR, the “OPEN”state.
So with a duty cycle of 10%, the IPR is “OPEN” for 10% of the period of time measured.
Nice video well done.
Is there any way I can contact you and ask you a few questions about the 7.3?
Great video my brother has 2003 7.3 we changed CPS and 2 sensors egr and icp behind the alternator the problem is rough idle and it dies we cleaned the fuel tank and filters could it be this sensor ipr that's is bad if there's any way to check with a olms meter thankyou
No need a scan tool...
