Thank you for what you do. I bought my first 7.3 3 weeks ago and it starts now after learning from your videos. I’m rewatching a rewatching trying to soak in the knowledge.

Loved the clapping sheeps!! Great personality, content, and sense of humor, Clint! Top channel on KZfaq IMO!!!

Another informative video! Great charts , you make this so easy to understand 👏 Keep up the great work 👍

You should put all your material on a thumb drive or a DVD and sell it.. if KZfaq ever goes away so does your material that we can get access to

Clint has the Best Professional 7.3 videos on KZfaq! My absolute go to for accurate and trustworthy information! Since you mentioned Forscan, KZfaq is seriously missing a good breakdown of how to use forscan in-depth abilities strictly for the 7.3 It would be great if Clint did a playlist for it.

Incredible 7.3 videos, your explanations are awesome. My f250 is 99' cc xlt 4wd lb she's all stock and a daily driver. Thank you Mr. Allen

Thx much for your excellent channel. I will not touch my 2001 Excursion 7.3 4x4 without checking your channel. Excellent info, simply stated. Followed your instructions on rebuilding my IPR. Engine more responsive and the hesitation is eliminated.

Thanks for sharing buddy! Love your tutorials! 👍👍👍👍🇺🇸🇺🇸🇺🇸🇺🇸🙏🙏🙏🙏

Lol enjoyed this and following. My first 7.3 and love this truck. I ordered the new wire harness and IPR. I was in the middle of a 3 lane highway at a light yesterday and truck stalled and would not start. While waiting for AAA. A guy pulled in front and waived me over from the sidewalk and he pulled me off the road. A few min later I tried to start and it started. I called my neighbor who has all 3 gen 7.3 trucks . He said, sometimes you can just unplug the ICP and get home so i unplugged it and it had oil on the terminal. He said the voltage could’ve been disrupted causing the truck to stop. Anyway, he mentioned changing a few other parts, including the wire harness, cam positioning sensor and IPR. Looking forward to reviewing your videos. Thanks

Another QUALITY video. Thanks sir!

this is Guatemala 🇬🇹 bless you America 🇺🇸 nice video I, like 👍🏼 thank you so much

I'm a believer , great information , just picked up a IPR at a Whopping $324.49 and the ICP was all oily inside so I figured I'll do that one to . I do have my concerns about the wiring . I am a non talented electrician . I usually make smoke , sparks or fire , of course not intentionally . But I will also look into a wiring harness being this truck has been butchered . I know what your thinking , maybe I should have looked at the wiring first . Long story short , I think I might be an idiot with a very low iq. I hope I spelled that right . .... Thank you for the information . I think I can start my journey with my newly acquired non starting 7.3 Now .

Hello Clint Another helpful video. Thank you sir.

I have started replacing the engine harness as one of my routine fixes/repairs for my fleet of 7.3s. Clint, you made me a believer!

Clint you have amazing content and have been a massive resource to me. I have three 7.3 work / welding trucks and you've helped me keep them on the road. one of my trucks has had a romping cold start problem I've been trying to solve for over a year and a half now. I am at my absolute wit's end with this truck. I am sure you are a very busy guy but I was hoping I could get in contact with you to discuss the issue. I have corresponded with a few 7.3 gurus as well as had a few look at it and no one seems to be able to figure out the problem, this issue seems to be quite unique but I have a strong feeling that a man of your knowledge base could solve the mystery with ease. Please let me know if you'd be interested in having a chat.

"You're still here, it's over." Pretty funny outro.

I recently replaced the lift pump and rebuilt the fuel bowl but when I unplugged the harness the plug for ipr was in terrible shape. I put it back together against my better judgement and had a no start. I now have a new ipr and harness sitting on the counter. Waiting to go in. What you didn't cover was the easy way to replace the ipr 😂 I'll probably end up pulling the fuel bowl back out unfortunetly. Not sure I want to buy a socket to destroy and use a punch like I've seen.

Excellent info thanx cheers 😊

Great video!

Wow! Great video!

Ok here’s what I have to do to start my truck. I disconnect the ipr . I have a separate connection to connect up that has 12 v and ground crank the truck over it starts shut the truck off reconnect the truck harness after disconnect the jump . Now crank it over truck starts right up . Crank pressure 480-490 . Replaced high pressure pump, pcm , ipr etc . Now it runs great starts easy if I start it only for a minute every 5 hours. It’s only cold start . The relay and glow plugs and wires have also been replaced.

Another thing to add there is a serious counterfeit issue with IPR for ford 7.3. Online you can get 7.3 IPR, oil pressure sensor and pig tails for under $50 there's a 100% chance they will be counterfeit. They may even come in what looks like an OEM bag. Look at it closely, it'll have errors such as instead of "trademark" it'll say "trademart". If you got one, it's counterfeit and will have rather questionable performance. If it works at all. Just a heads up. That shaft the coil sits on the IPR is a relatively thin walled tube. It can be easily bent, if you slip, or even drop a socket on it. If that happens there's a high likelihood the IPR is shot. I've straightened them out by disassembling it successfully, but it's not easy.

Clint, I love your videos. I know you get tons of questions from viewers but I'm stuck with a unique situation. I have a engine vibration on my 95' 7.3 that goes away at a certain engine temp. Its been going on for sometime now. Idles fine but engine shakes at ambient temp goes away at about the "O" in normal then returns at operating temp. Anyone eles experience this. I'm pretty familiar with my truck and have tried everything. Good oil New CPS New fuel filter Pass buzz test Ohm injector harness all 3.0 All injectors make a noticeable difference when unplugged while running ICP unplugged idle gets worse No smoking Fuel PSI at idle 40-50 PSI Sometimes hard starting but I'm due for batteries in this Phoenix heat.

I support this content.

I just got a 7.3 f350 Centurion and it's stalling but it fires right back up so I'm thinking it's this. I ordered one but I'm about to rebuild the valve that's in it now and see if i can get it running smooth while i wait for the part to come in. Might as well order a wiring harness as well.

Might want to add a blurb regarding the differing IPR types (edge filter vs non-edge filter). Granted, the edge filter types were only use on 94.5 - 95 engines up to engine serial number 187099. Early edge filter IPRs have a flat closed end, while the later non-edge filter IPRs have an end that looks like a gun barrel. Cheers!

Thank you Clint Another very informative video If it is not a problem can you please tell me where you are physically located besides U tube Again thank you very much and have a great day

Hey Clint! Since you are the only guy I'll trust 100% of the way when it comes to the 7.3 I have a question for you. Just started my truck up and noticed an erradic idle. Saw it reflecting in my hpop gauge (spliced into the ICP sensor wires) after driving home and idling again, idle was smooth, however I could see the HP oil pressure fluctuating a little (but it sounds like that's normal) Recently replaced the IPR valve w/motorcraft a few months ago. Think it got something stuck in it?

Great video,i have a crank no start,this all happened after i installed a new hpop and new valve cover gaskets and fuel bowl also new wiring harness and new ipr and icp truck wont start it was running and died goin down the road and wont start. I havent checked for injector blowout

Great video. I had a no start “hot” situation. Truck start cold ran good but on restart while hot it would crank and crank. I pulled IPR and 1 of 2 orings on the end was damaged. Replaced it and now starts at all situations. Was frustrated with all the time I messed around with checking different parts. Everything was checking out until I dug in and actually pulled the IPR and saw the little oring damaged.

Hi, I've got a early '99 F250 and have replaced pretty much every sensor, rebuilt injectors, etc. The truck cranks and runs fine cold but as soon as it starts to get a little warm, it'll have a very slight fluctuation(surge up & down) in rpm where the needle barely moves but is noticeable. The ICP is a new aftermarket brand, no oil in connector, and pressures seem fine (around 700psi cold then slowly drops to around low 500's range warming up) but when I unplug the ICP before cranking and try to start, the truck will have a hard time starting, wildly surge if it does fire off, and have to hold the accelerator pedal down at least half way just to maintain 1500 or so RPM and as soon as I let off the pedal, the truck dies. I've watched a lot of videos and checked all the normal things and have no idea what else it could be. I'm also getting no CEL. I do have forscan and a programmer that shows the IPR, also an aftermarket brand and new, is around 25% cold then slowly goes down as it gets warmer. I can't seem to find anywhere else talking about the truck not starting at all with the ICP unplugged as the PCM should have a default parameter.

I don’t know much about these trucks but I do know I like international engines it’s hard to find a place to put a new oil pan gasket but she’s pretty mint for a grand

Clint, need help! When the oil is below 160 degrees (start up or restarting after cooling down) the motor will run fine and then idle up 1000 rpm’s and settle back down. On Forscan I can watch the IPR build % until it reaches 40-42% and crash again. It does this until the oil heats up. I’ve changed out (with Ford parts $$$) ICP, CPS, EOT, IPR, UVCH, main harness, New Fuel pump, stage 1 HPOP, High voltage IDM, not sure where to go from here. Not sure why the IPR would cycle like that? Any help would be appreciated. Once the oil heats up, it’s a dream to drive. Thanks so much

High Clint I have a quick question for you maybe a stupid question. So I am looking at buying a 1998 international that has the 444T engine which is basically the same as the ford 7.3 powerstroke Both made by Navistar. The truck I am looking at has a problem that it will start up but won,t stay running. Will the Test you said to do be a good indicator follwing the ordered you laid out be a good cause of the issue. Thank you for your time sincerely, Brad

Hi, is the HPOP pid available in the light version of FORScan? I can’t seem to find it. Using ODB2 Wi-Fi reader. Thanks!

I did the fuel bowl delete for my 1997 OBS .The kit still keeps the Mechanical fuel pump. With the fuel bowl gone it makes getting to the IPR so much easier. One time the pigtail connection went bad ,intermittent no start issue . Easy access with no fuel bowl

I got rid of that steel nut and put a Real nut on and has NOT backed off since. I was having problems of that nut Always backing out and dropping off and dropping into the valley.

Right on

Been troubleshooting wo use of obd. Cannot start it. Well over 500 psi oil the car gauge goes to bout 700 well above the 500 standard. Sounds like it catches but won't go. New ipr cheap but got the pressure. Icp seems bad as it's new but truck doesn't catch with it plugged in. Changed filters in tank, bout to change heater in bowl which seems unnecessary and also bowl filter

Only thing I missed is, what if a shade tree mechanic pulls the non-servicable plug out of the hpop never sees it and either it falls out or it rolls somewhere else in the pump. Either way this could cause a no start bad ipr read.

I am working my way threw a p1211 and after watching this I realized my syloniod is mounted backwards do you think that would cause it

haahhahha i like this guy thank you!!!

I plan on using it as a cruiser maybe do something to boost a bit of mpg it already gets better then my 97 Tahoe with mud terrains

Do you recommend a obd2 scan tool that isn’t the one in the video I can’t find that one sold anywhere and the link you have says unavailable

clint can you tell me how to join this forum. where do i get to buy an engine harness for the 2000 7.3 power stroke

Can you buy a rebuild kit for the IPR

Hi I have been researching many of your videos since I recently purchased a 97 7.3. I have a long crank issue (approx 10 sec cold or hot). Low ICP pressure when cranking. Once I get it started, it runs fine. If I turn off the engine and then turn the key back to the run position immediately, it will start back up without the long cranking time. (even if I let it sit like this with engine off/key on for several minutes). By keeping power to the IPR this way, does it somehow prevent oil pressure from bleeding back to the pump from the heads? It doesn't make sense to me that putting the key back on would make my long cranking issue disappear

My van runs fine but i have a code P1211 the only thing i noticed it does cracks a little more when starting than before do you know what could my problem be?

Thanks

Can you please throw a link in for where to get a replacement harness.

Where are you getting your wiring harnesses? Great content, thanks for the hard work on getting this info out to us 7.3 owners

Two times over the past year I have had my '03 7.3 (Excursion) shut off unexpectedly. Both times in a drive thru line, and both times it started right back up. No other issues or symptoms, and these events were probably 6 month sapart. This past week it shut down while my wife was driving it (probably going 30 mph thru a residential area). She was only about 5 minutes from the house, and it had not had a chance to get warmed up as she had just started it and left for the store. It would not restart right away. I was home so I went to meet her to see what I could do, but before I got there she tried it again and it started just fine. She made it to her destination, and I switched cars with her and brought the Excursion home (no problems). I am leary now to take it out until I figure out what might be wrong/failing. (It had just completed 1k mile trip the week before with zero issues.) I am going to load up the ForScan app and see what the beast will tell me. Anything I should be looking for a very intermittent issue? It's not a true crank no start situation in the traditional sense imo. Thanks!

so, is there different IPR'S for the 7.3? i ordered a motorcraft part number (cm-5013) and it has a different piston in it, and right at start have max oil pressure. pulled apart and compared to your video. looks identical, exept for the pison inside the barrel.

Why does my 1997 f350 call for ipr 2C3Z9C968BA ....1994.5-1995.5 style ipr valve when I call the dealer to buy a replacement?

I have an OBS 7.3 and randomly started have a mis and loss of power while driving. I pulled the lines off the lift pump and blew them out. Even put a feed line into a can of diesel and can’t get the truck to fire now. Fuel bowl stays empty unless I fill it manually. Do you think the lift pump would be the cause possibly?

7.3 noob question. What year was the first year of OBD II on the 7.3?

Could you please let me know where to buy the IPR from I called the Ford dealership and they said it was $700

Hey Clint. If I traveled and needed some tools to repair something that might go faulty. What would you carry in the tool bag and what parts would you carry? Thanks for your input.

Where on the FORScan app did you find the option to see the hpop? I have everything but when I plug my 01 in.

Is there a after market top engine harness you would buy? Or just get the OEM from Ford?

Location, location :) So there's my 1972 F-250 behind ya A, at the 1:02 mark, But the the IPR ain't behind my distributor... A :) But! I found the Bugger hiding under my Fuel Bowl on the hpop on my 2000 7.3 Grocery Getter :)

Hallo can you help me? I have changed the IPR 2 times I still have about 2000psi according to forescan what can it be please help. Martin

why did you not mention the rough idle and die until the engine warms up or if you leave it plugged in overnight? Mine would start and idle extremely rough and die for several start ups until the oil warmed or l left it plugged in over night-once it was warmed up it ran fine-I replaced the IPR and have not had any trouble since

I changed my ipr valve and it’s sensor… now the service light is on… was not on before… what did I do wrong

My ipr the ohm is reading 30.2 is this a bad ipr coil?

What should the ipr % be while cranking?

Can't find Bafx products, any sugestions

Hey Clint , what's a good reputable place to order a Adreneline High pressure Oil pump for my '95 Powerstroke truck wood really appreciate your inpute thanks Carlos

My 1996 F350 isn't compatible with the ATS3 Monitor, would the OBD II reader work? I'm guessing no, because my truck is like OBD 1.5, it has the connector for OBD 2 but it has very few contacts.

Hi Clint love your videos! Wondering best and safest power upgrades to improve hp and torque. I thought you said for around $2500.00 parts one could vastly improve performance. Do you have a video on this or any suggestions. Pull a 12000 lb 5th wheel

So where do I get a wiring harness.

Thanks. Great content. Maybe I missed it, but that tiny pin is hard to see. If you didn't say so, can you tell us which direction the tiny tiny end of the tiny pin goes?

Where is a good place to buy?

witch way does the SMALLpin go into the ipr , one end has a point on it ??

Wen I’m full throttle and go throw the gears I get 65% ipr duty cycle an throwing a p1211 icp reading good no oil in my icp so do u think it the ipr I think it by watch the pids on my edge cts2 and truck starts right up in cold weather and hot I’m in Cail I’ve have her for 2 years

How much does the wiring harness cost?

I have a 97 f250 with the 7.3 power stroke diesel. I start it up it idles at between 600 and 700 rpmsand sounds good no miss I hit the throttle up to 2000 rpms with no problem no miss no smoke all day I can do it but when I drive down the road soon as I hit 40 mph the check engine light comes on and the runs rough and slow or no throttle the engine will stall if I don't shut the ignition off and I restart the engine runs rough and no throttle. If I turn the ignition off and restart it it runs great until I drive down the road and hit 40 mph and the same thing happens. Please help. PS I watch all of your videos and theres nothing on this problem.

Does the upper wiring harness replacement connect to IPR on an OBS truck?

Hot no start issue today. 12 minutes it died. Crank no start. Hpop res. Full and fuel bowl full. Disconnect newer motorcraft ICP no difference. Wait 2 hours fored right up. Drove 6 miles and died again. Wait 2 hours and starts right up. This is definitely a pattern now. I read somewhere that the magnet solenoid on the IPR can fail with heat. I will ohm test when cold then ohm test once hot and failed. Any experience with a situation similiar?

Hi

WHERE CAN I FIND A NEW HARNESS FOR MY 96 F350 7.3??? ALSO LOOKING FOR A HARNESS FOR MY 2000 E350 7.3 ???

I have a 95 e350 7.3l with very low power, very slow acceleration, all I've done is fuel filter relocation and electric fuel pump and regulated return. I have 65psi of fuel pressure, 600-1300 psi oil pressure, map is new from Ford with the hose, New Baro Sensor, ebpv delete, 4inch inch exhaust. Cel on for p1111 I don't know where to go from here.

Brand new Oem Ford Icp and brand new Ipr ford oem. Icp pressure goes straight to 5000 psi???

Clint, is there a way to bench test the IPC Sensor?

Can you run seafoam in the engine to help clean everything on the 7.3?

Where can I buy a new wiring harness for my 2001 7.3?

Is 4-6% at a hot idle normal for ipr percentage?

If this is the issue will it start most of the time and only not start about 20% of the time?

The crank sensor going bad shut one off at an idle 95 7.3

2002 7.3 What is the hpop psi on idle 300psi or 500psi?

Where can a person find a new engine wiring harness?

Where do you get wiring harness from

changed IPR- now it's hard to start and runs very very rough. OEM part ( not cheap or fake) ...

Hello, my name is jay and I work as a mobile diesel mechanic in California. And few weeks ago I was call out to check out a 1997 ford 7.3 For a stalling and hard restart sometime would not start till next day. And before I was called out I was told the truck was at two different shops trying to figure it out, and many new parts thrown at it ( all dealer parts ) icp,camshaft sensor, injector seals, hpop , ipr, fuel pump. I was able to duplicate the issues, to me I was almost 100% it was the cam sensor because it would almost stall then turn it self back on in a split second or just stall as if u turned the off the ignition With no sign of fuel starvation or oil. After it stalls it’s very hard to restart most of the time or sometimes it will fire right back up. But when it wouldn’t fire I’m not getting no high pressure build up past 190 psi, now I got 20psi on the low oil pressure side, oil reservoir full, fuel pressure at 55 psi cranking , when I put a pressure gauge in two the high pressure oil rail I can see it’s matching the scanner more less at 190psi. I got battery voltage at the ipr red wire with signal never dropping out. And from what I can see the computer seems to be sending the duty cycle the yellow/red wire when I hook up my power probe Duty cycle jumps from 20%-80%. If i disconnect the icp sensor still no start. What I do is ran a jump wire from battery to the ipr valve and truck starts right way. Now I do see that I’m getting a duty cycle on the yellow wire but I guess is there another way to confirm I might have a bad Pcm I hooked up a light bulb from the red to yellow wire to see if the tone of light will flash but when I connect the bulb in it stalls the truck. So please if u can get back to me on guidance on a proper diagnosis from here thank you

I came upon you weeks ago your like diesel tech Ron but for 7:3 I love all your vids do you have injectiors, installation and new injectiors.

I need some info please, I have a 2000 7.3 , got home Sunday night running fine, Wednesday morning crank no start. Live in alaska and pretty good ride to start getting parts to throw at it. New oil change, fuel filter. Cranks fast and tach works. Figured out that it'll start on starting fluid . No spray no run. Got fuel up to bowl.
