Just want to say thank you. I am 600 miles from home with a camper on the truck and pulling a trailer. I stopped at the Salton Sea in California to go kayaking at sunset and afterwards the truck would crank but no start. I found your video and went through the list. The Injector Pressure Regulator coil measured at 400k ohms and it should be about 10 ohms. I slept right there and this morning I used my dual sport motorcycle to go to Napa, 22 miles away. They had a new Napa brand IPR in stock (for the bargain price of only $360). I swapped in the new coil and she started right up. I'm about to chooch home but had to thank you first.

LOL'd at the homage to Ferris Buller at the end. Trying the trick of disconnecting the ICP tomorrow, as well as removing it to check the IPR. Already swapped out the fuel filter and Cam sensor. Been down a couple weeks now and it's annoying taking the bus. Had the '95 F250 out here on the Big Island going on 5 years now and just had my first piece rust off last month...
Replaced the IPR and fuel pump and it still would not stay running. Pulled the plug on ICP and it ran, a little rough but it ran. Replacing the ICP tomorrow.
First time on your channel.great info all solid advice .im struggling a bit with one of these monsters .im sure ill get it straightened out following your advice
I have a 2001 7.3 excursion that was repeatedly blowing the pcm fuse. J-case 20A fuse #113 in my case. I found a short in EOT sensor harness, and after repairing that it stopped blowing fuses. Now I have a no start again. P1210, and po231
Do you have a preference on wiring harnesses? I drive a 2002 Ford F350 super duty with a 7.3. It currently has 447,444 miles on the odometer. I replaced the engine with a pilot motor at around 404,000.
I don't mind spending the money, but when Ford tells me a $170 for a part. They sold 2 years ago for $79. This is ridiculous I told them no no no more games and hung up
My 2001 f350 was running fine my son drove it to work and home he parked it in the driveway and went in the house for about 2 hours went back out to leave and truck hasn't started since. My hpop ipr was still plugged in and wire at plug is good. My tach isn't moving during cranking so I replaced the cam position sensor. Still no start I drive a big truck and had to leave so I still don't know what the deal is. Worst part is it drove home fine and just didn't start again. And I unplugged the icp and it didn't crank.
Good evening hey I got a 2002 F250 super duty and it’s only firing the driver side passenger side is not doing anything at all could you tell me maybe what the issue could be?
Gonna have to disagree about the glowplug light/no glowplugs. Really depends on outside temps. I can jump in my 2000 7.3 with 400K and do an immediate crank with quick start in 70 deg. F weather.
Привет парни.Я владею F-250,7.3,2001г в России.Ваши ролики мне очень сильно помогают в ремонте.У меня проблема-у нас не найти моторный шлейф проводов.Прошу помощи в приобретении!!!Я даже номер для заказа нигде не могу найти.Спасибо.
Да именно это.Благодарю за ответ,долго искал и нашел его на АлиЭкспресс.Понимаю,что это не самый хороший вариант,но сейчас другие не доступны к сожелению.Ваши видео очень помогают.На канал подписан.Удачи Вам!Здоровья!
I'd check the gear to make sure its not spinning, the reserve is full , the check ball didnt fall out and all O rings didn't get cut, rolled ,nicked ,incorrect stacking
Starting to get white smoke now scan tool is reading pressure climbing up when cranking just not quite getting to 500 psi big air lock I think thanks for your time .
I did make the mistake of not filling the oil reserve would that make it harder to get going sorry to hassle you but iam at a loss and no one wants to no about 7.3 s around here Australia thanks for the help keep the videos comeing they are great.
@@tonyreeves7391 I thought of that after the fact but I assumed this would be a given But yes injecting air into the system would make it a real bugger to get going
Mr.Allen, thank you for teaching us your wisdom on the old girls. Saving your videos for my kids when they get my 10/99 Lariat 7.3 crew cab long bed automatic. As of today it has 15,120 original miles on her.
Found a 97 fsuperduty 7.3 power stroke in a junk yard I bought it they said it had a bad engine come to find out the ipr valve was bad it cranked right up love your videos thanks for making them
Need some expertise. Have an 01 7.3 blew an oil line about 2 weeks ago. Changed that out and started up twice no problem. Cleaned out the engine bay low pressure water and now still no start. Have fuel have good fuses have good relays. I’m noticing a clicking from the fuel pump relay in the dash. Changed that out and still clicking while cracking and no start. Have new oil and filled properly. I’m leaning to the glow plug relay. But not sold on it yet because all lights do appear on dash
Oh hey Clint I'd like to see a video on "Tools needed for working on a 7.3L". I haven't really seen any videos on that and it would be nice if someone like you with the experience and knowledge would show us what it takes. Some simple tools for us driveway mechanics and some more professional tools for those who can afford them. Obviously the Bluetooth OBD II and suggested Software to run with it. Maybe some Compression testing tools and tips etc. Best Wishes & Blessings. Keith Noneya
1 1/8 inch socket for ICP sensor. 10mm short and deep sockets for the pcm. Idm and engine harness. 13 mm short socket and deep socket for valve cover bolts and studs, starter relay. Odb2 adapter paired with torque pro. 8 mm for the injector hold down bolts. Car Guage pro for pcm idm tests torque pro can't do. One thing I would recommend is using an old valve cover gasket connector and splice them into test terminals you can hook a voltmeter up to in order to test the resistance of all the injector solenoids and glow plugs. Just ensure the gasket is good to go or else it'll throw off readings. 1 inch deep socket with 4 inch extension 1/2 in ratchet for manually turning crank. For compression testing you can remove the glow plug for either cylinder and find something with a 5/16 thread and a 10mm nut like a brass plumbing fitting that connects to a vacuum gauge for compression testing since the glow plug goes in the top of the cylinder/head. For fuel pressure you can buy a 1/8 npt fitting from riffraff or Amazon for gauging fuel easily from the bowl.
Clint, my 16 y.o. son has an '01 PSD . It currently starts, runs scrappy for 3 seconds, then dies. Any ideas? We've recently changed oil/filter and fuel filter. Changed the camshaft sensor when this problem popped up.
Thanks for uploading these.. You've made me think about preventative maintenance I've ignored for years.. Always great full of talented people sharing their knowledge..
Please start a 7.3 store! PLEASE PLEASE PLEASE THINK ABOUT THE ISSUES YOU'VE HAD ! THINK ABOUT A Novice looking through this nightmare window of part hunting... ford has now tripled the cost of every single part
@user-zb5nc5ke2h they don't make half the stuff anymore.. you find it we'll buy it.. 750 bucks for a stock tank switching valve. 86 bucks lifetime warranty
with the key in "run/on", i have 12v, not 5v, at my ipr connection... i havent pulled the ipr out yet to test its coil resistance. assuming there is no such thing as a 12v coil, i will not only have a fried coil, but also will need to figure out why i have 12v to it instead of 5v... wiring harness issue?
@@CUSTOMWORKS7.3PSD ok, good. well, at this point then i have narrowed down the potential culprits to; possible bad IPR, possible bad HPOP, or maaaaaaaaybe a weak fuel pump. The fuel bowl does refill, so i dont think that is it (though i dont have a way yet to measure the pressure- looking for a min of 50psi, right?) Next steps are to pull the IPR, test coil resistance and air-flow test, then get a way to accurately measure fuel and oil pressures.
Im New to 7.3 and so far loving the truck. We yesterday i did its 1st oil change as a 3rd owner and clened tge engine bay alitle bit took the truck for a spin. Came back parked it overnight, tryed straing it this AM and cranked but wont start lolo😂😂😂.... It has fuel, new oil and filter but the batteried are dying now lolo.... What could this be 🤔🤔🤔🤔
2000 EXCURSION 7.3 Started misfiring on acceleration for about 5 miles, then just shut off and wouldn't restart. Scanned and got these codes. P1670 (Electronic feedback signal not detected) P1280 (ICP Sensor Circuit low) P0478 (Exhaust pressure control valve high input) I disconnected ICP, still no start. The electronic feedback code has me thinking its the PCM however , when i turn the key forward I get the glow plug light and check engine light, Where should I start?
I for got to put scanner that I found in my previous comment FORScan ELM327 OBD2 USB Adapter for Windows, Diagnostic Coding Tool with MS-CAN/HS-CAN Switch for Ford Lincoln Mazda Mercury Series Vehicles
Maybe you can help me. I have a 2000 7.3 diesel dually truck. I just want to give you a list of things I've done and still no start. Fuel pumps been changed. High pressure pump been changed. All sensors have been changed with OEM sensors. Pcm and IDM I have been checked. . All fuses are good. Any other ideas would be really appreciated
I'm at my wits end with the starting issue I'm dealing with on my 01 7.3 that was gifted to me by my brother, so it's sentimental and I WILL get it running. But any input would be great! I'm pretty capable but diagnosing this issue is beyond me.. I just changed the solenoid on the fire wall and got a few cranks, but then right back to a single click when turning the key. Bad ground? Frying these solenoids ? Idk. Anyone with any experience with this. I would really appreciate it
Thanks for another great video. I fought through many issues with the hard/no start. The starter just sounded weak. A new starter, powermaster, did the trick. The truck started an ran well. BUT about 2 weeks later; Got in, turned the key, all the lights illuminated, normal, Turned to start and nothing, everything went dark. Any suggestions?
Man, where have you been all my life!! Absolutely love the delivery, and I love to learn. Pulled out my fuses 1 at a time, checked them and put them back in, because I couldn’t figure out which fuse controlled my mileage and temperature gauge. Truck hasn’t started since!! I’m just going to change out the sensors, change the filters and oil, and clean up the engine !! I’m not sure the original owner ever lifted the hood. I needed this video Thank You
Just wanna you are very very very smart guy , love your videos and I just bought a used 2003 f350 7.3. Not running of course is how I get such a steep discount of 2k to buy it And hopefully soon be running strong with all your info. I have personally wrote down your punch list. Thank you !! For a very very good video and many more I’m going to watch. Thank you again !! From Shawn ❤
mornin, recently i installed a new hpop on my 2001 f250 7.3 and bew valve cover gaskets,it seems the truck idles a little faster but the main problem is after driving it and shutting of for maybe 2 hrs when i hit the key it spins over like it will start but and after doing this a while it;ll start last nite this happened and i just happened to put my ful pedal down a little and it fired right up. im confused
Issue I’m running into 2003 7.3 always runs wonderfully started at one morning idling nice and smooth and just shut off. Cannot get it to restart and have it invested a lot of time and diagnosis other than the obvious position sensor change no good plug the sensor on the right fuel no start still just have not had time to diagnose when it’s spinning no smoke or anything of that nature no white smoke just wondering Place to go next for diagnosis
I ran out of fuel one day on the road and it died on me come to find out the gas line from the fuel sector disconnected itself and now it doesn’t want to start. Already leaked the air from the gas bowl any advice on what it could be? It did shake pretty bad in first gear jumping and what not before I ran out of diesel on the road.
I bought a 97 that supposedly ran out of fuel and sat for many years as it was running and died, started back up and went a block and never ran again. When I got it. I put new batteries in it, was cranking it over to get fuel up and the IDM blew up so I bought another one, ran the scanner on it and the injectors cycled. The hvop reservoir was empty so I filled it up and it drained immediately, I'm not getting oil into reservoir from lpop even after cranking several times, haven't checked the check valve yet but suspect injectors might need rebuilt one I get oil into the hvop. Your videos are a great source of information as I'm an ASE Master tech, not real familiar with the 7.3 other than is over built for passenger trucks. Mine has 275000 miles on it and going to get a million more out of it.
How can the fuel bowl heater make it not start? Mines been disconnected for some time now and has always started and ran without it connected. Maybe thats my issue now?
I have enjoyed your videos, very informational ! You say the engine wire harness should be replaced under normal maintenance . Where do I find a new harness? Ford says they are obsolete! I have a 2000 E350 7.3 powerstroke.
My old 95 e-350 7.3 died as i came to a near stop to make a turn. Started right back up. IPR has about 50,000 miles on it. I remember from past research my problem could be the crank position sensor. Do you agree? Thanks so much.
I have a 99 7.3 4 x 4 the engine is stuck won’t turn over I pulled the glow plugs thinking it might be hydro locked but it is not. I think the condensation accumulated in the cylinders over the course of five years not being run. And rusted the rings. I’m now soaking the cylinders, but it just doesn’t seem like that’s the problem either. Is there something I should be checking before I continue going down a rabbit hole? Thanks
If the engine turns with the glow plugs out off the crank with a ratchet Then I have run into trucks I have had stored for years , starter went to rust , connection at the starter bad , transmission torque converter stuck or clutch , Injector stuck contacting the solenoid do a buzz test (FORSCAN app via your phone)
For something like an ICP or alternator, I actually go with a parts store part with a lifetime warranty. Only because I can pull in and swap it in a few minutes and if there is an issue I can unplug the ICP and get to the store.
2 years ago I ran TS6 chip with custom tunes for my BTS transmission. Which made it a completely better truck. But I had a problem with it on a intermittent issue which felt like dropping 1/2 the cylinders. I had previously had the L. Valve cover off and fixed a bad plug connection so I was familiar with that issue. Being in south texas for the winter I found a old farm shop that was able to read the 7.3 codes. It took a while but after removing the chip the problem was gone along with the needed HP to pull our 5th wheel. BTS programed a new chip and sent it to me at no charge . Before heading south i decided to replace the valve cover gaskets and wire harness this year . Even though the truck was running good . The harness plug was loose under the R. valve . And also replaced the glow plugs. Money well spent. You talked about replace all the sensors, I wish some reputable business had a package with all the sensors at a reasonable price. I've replaced the ICP sensor so I know they are expensive. On a 01 7.3 ,186k miles. Thanks again for the great info.
Mine started out acting like it was running out of fuel. Made it home changed the fuel filter and it ran great, drove it around for a couple hours with no issues. 2 days later started the truck made it about a mile and it died, towed it home. Now it starts but only runs for about 15 second, if I touch the fuel peddle it dies instantly. Drained the fuel housing looked like it had water in the fuel. I treated the fuel and changed the filter a couple of times in between the 15 second runs but I have made zero progress in resolving my issue. Any advise?
FOCUS ON IPR, ICP, CAM SENSOR, Wires and connector I have video's on all of these also get forscan to do monitoring and diagnosis If those all check out then its a IDM or Injector issue IDM can be monitored with forscan
Thank you for all the information that you’ve learned with the years and sharing some of your knowledge. Also adding the quote “I’m not going to tell you everything I want you to know your truck” that makes me want to get in it even more! Thanks a lot for pointing out the most regular problems and for sharing. Again! I really appreciate these videos.
Hello sir I have a 2001 ford f250 super duty. My problem is the truck only starts when I plug it in. I just dont understand what the problem is. Thank you in advance sir.
This channel is so good I'm watching videos about issues I've had in the past and resolved just to see how well he explains it and if I had this video alone a few years ago I could have atleast 10 hours of my life back I wasted trying to compare different videos etc. I've had my 7.3 since 2013, If you are kinda new to the game there's no need to look any further, this is the best channel .
Very comprehensive video. Old guy with a 1997 F-250 CA emissions, 120 k miles. Never had any expensive problems since 1997. Just crank sensors and (1) IPR change. Had an issue popping up this winter. cut out, no start. Think it was water in fuel issue. Thank You for helping. I'm locked on to your videos.
Quick question, will my 7.3L start with the turbo pipe off the compressor side of the turbo? Will they run or start with one or both of the down pipes off?
@CUSTOMWORKS7.3PSD thank you, I just Rebuilt the injectors and can not get it to start for nothing, I followed every singke step in all your instructions, even pissed off the ol lady using her new shop vacuum LOL. I watched every singke one of your injector videos, and more, I've checked voltages, harness, everything, am at about a total loss of possibilities 💔💔💔😢😢💔. It won't even kick with small shot of starting fluid, other than a small back fire when I tried that. Now just small white cloudy smoke perse, that I think is only un-burnt diesel fuel Perhaps the CPS took a crap on me? Going to pick up a new one today. What are chances of that happening? I'll look at my RPM gauge before I go spend $70 on new one. I replaced the one in it last beginning of Fall or Hunt season.
From what I’ve seen you’re one of the most knowledgeable PSD people I’ve come across. I’m at a loss for things to check I have a 2000/7.3 that was removed to repair a broken bolt in the water pump, don’t ask I didn’t uninstall the engine I can’t get the engine to start I did all your checks and no start. New fuel pump & batteries glow plugs ok oil in HPOP IPC IS New disconnected still no start I have no scanner to check HPOP out put. Is it possible the LPOP lost its prime and can I remove the OP sending unit and pump oil in to prime the oil pump. Also the starter seems not to crank as fast as the videos I’ve watched. I’d hate to replace the IPM if it’s not bad. I’m an GM wrench and worked on many GM Diesels I rebuilt many standing injection pumps I’m pretty handy with a wrench and hate to replace parts not needed but I’m at my whits end any suggestions would be appreciated also I disconnected glow plugs and tried WD40 we started GM diesels with WD and tried some either and it doesn’t even fire I’m lost can you advise.

Thanks so much for your 7.3 videos! I’m experiencing a problem with mine that has me baffled. This is a 2002 model f450 with only 5800 miles. Obviously bin sitting much of its life. The problem is when cranking for start hpop doesn’t build for 6 to 8 seconds. According to the scan gauge I have connected. Will the ipr pid today too determine its position through this scenario. This is regardless of ambient or engine temp. It then builds pressure starts and runs normally . The crank rpm seems normal. I checked the oil level in the reserve chamber and it remains full. Would a ipr or hpo sensor cause this problem? They are next on my list but I wanted to check first before throwing additional parts at it. Btw the oil is fresh 15/40. Thanks
I wanted to get the scanner you listed but was having trouble finding it here is one I found that is wired which is fine for me to my laptop WILL it do all that the model you recommended??? I haven't ever asked a question on TH-cam.
Nice content. Thanks. I have 0 experience with the F250 7.3. But since I just bought a police impound machine at auction I have to get it running and driving. 34:33 With 0 history known I was looking for the proper sequence of Trouble shooting. Did not have any idea where to start. Now I do. My 2 cents.
I have a question for you sir, I am fighting a crank no start with a constant check engine light. At the end of the buzz test the SES light turns off until the key is recycled. What can this be an indication of? I do not have rpm on dash and have verified continuity with cps, and pcm to IDM. New IDM as well
Bypassed the IPR and truck started but not smoothly, Saw in akother video the same thing started the truck, After the guy replaced the harness it cleared up, would you recommend an aftermarket wire harness that's not as expensive as oem?
Just want to say thank you. I am 600 miles from home with a camper on the truck and pulling a trailer. I stopped at the Salton Sea in California to go kayaking at sunset and afterwards the truck would crank but no start. I found your video and went through the list. The Injector Pressure Regulator coil measured at 400k ohms and it should be about 10 ohms. I slept right there and this morning I used my dual sport motorcycle to go to Napa, 22 miles away. They had a new Napa brand IPR in stock (for the bargain price of only $360). I swapped in the new coil and she started right up. I'm about to chooch home but had to thank you first.

@@CUSTOMWORKS7.3PSD good evening what would be the first step to look into I almost believe on the harness but I’m not sure
I dont even have a fuel bowl heater is not in the housing and runs lol
Gonna have to disagree about the glowplug light/no glowplugs. Really depends on outside temps. I can jump in my 2000 7.3 with 400K and do an immediate crank with quick start in 70 deg. F weather.
Has your truck ever ran without the gpr system connected?
No it hasn’t sorry this is my other account
Привет парни.Я владею F-250,7.3,2001г в России.Ваши ролики мне очень сильно помогают в ремонте.У меня проблема-у нас не найти моторный шлейф проводов.Прошу помощи в приобретении!!!Я даже номер для заказа нигде не могу найти.Спасибо.

What's your thoughts
I want pizza 🍕
She just needs a little Cosby sauce.
Where can I get a new wiring harness for my 2001 f350?
Working on a stand alone video for this just waiting on some companies to get back to me on stock and guarantee's
7.3 power stroke will start on ether won't stay running what's your thoughts
I'd start with codes then fuel system Hard to say with out being there but could be as simple as a failing pump
Fuel has good pressure 60 lbs could it be the idm
At 5:58 you are showing a 6.4 fuel filter
we know just tells a story
Hi mate just resealed my hpop put it all back together and she well not start any suggestions would be appreciated thanks
I'd check the gear to make sure its not spinning, the reserve is full , the check ball didnt fall out and all O rings didn't get cut, rolled ,nicked ,incorrect stacking
Starting to get white smoke now scan tool is reading pressure climbing up when cranking just not quite getting to 500 psi big air lock I think thanks for your time .
She's a stubborn old b###h pulled the pump out again all is good have read they can take a lot to get going again.
I did make the mistake of not filling the oil reserve would that make it harder to get going sorry to hassle you but iam at a loss and no one wants to no about 7.3 s around here Australia thanks for the help keep the videos comeing they are great.
@@tonyreeves7391 I thought of that after the fact but I assumed this would be a given But yes injecting air into the system would make it a real bugger to get going
Mr.Allen, thank you for teaching us your wisdom on the old girls. Saving your videos for my kids when they get my 10/99 Lariat 7.3 crew cab long bed automatic. As of today it has 15,120 original miles on her.
Found a 97 fsuperduty 7.3 power stroke in a junk yard I bought it they said it had a bad engine come to find out the ipr valve was bad it cranked right up love your videos thanks for making them
👍
Nice
Need some expertise. Have an 01 7.3 blew an oil line about 2 weeks ago. Changed that out and started up twice no problem. Cleaned out the engine bay low pressure water and now still no start. Have fuel have good fuses have good relays. I’m noticing a clicking from the fuel pump relay in the dash. Changed that out and still clicking while cracking and no start. Have new oil and filled properly. I’m leaning to the glow plug relay. But not sold on it yet because all lights do appear on dash
Oh hey Clint I'd like to see a video on "Tools needed for working on a 7.3L". I haven't really seen any videos on that and it would be nice if someone like you with the experience and knowledge would show us what it takes. Some simple tools for us driveway mechanics and some more professional tools for those who can afford them. Obviously the Bluetooth OBD II and suggested Software to run with it. Maybe some Compression testing tools and tips etc. Best Wishes & Blessings. Keith Noneya
1 1/8 inch socket for ICP sensor. 10mm short and deep sockets for the pcm. Idm and engine harness. 13 mm short socket and deep socket for valve cover bolts and studs, starter relay. Odb2 adapter paired with torque pro. 8 mm for the injector hold down bolts. Car Guage pro for pcm idm tests torque pro can't do. One thing I would recommend is using an old valve cover gasket connector and splice them into test terminals you can hook a voltmeter up to in order to test the resistance of all the injector solenoids and glow plugs. Just ensure the gasket is good to go or else it'll throw off readings. 1 inch deep socket with 4 inch extension 1/2 in ratchet for manually turning crank.
For compression testing you can remove the glow plug for either cylinder and find something with a 5/16 thread and a 10mm nut like a brass plumbing fitting that connects to a vacuum gauge for compression testing since the glow plug goes in the top of the cylinder/head. For fuel pressure you can buy a 1/8 npt fitting from riffraff or Amazon for gauging fuel easily from the bowl.
Clint, my 16 y.o. son has an '01 PSD . It currently starts, runs scrappy for 3 seconds, then dies. Any ideas? We've recently changed oil/filter and fuel filter. Changed the camshaft sensor when this problem popped up.
Thanks for uploading these.. You've made me think about preventative maintenance I've ignored for years.. Always great full of talented people sharing their knowledge..
Thanks for what you do! Your videos have helped me greatly to keep my 7.3 running strong! She just hit 1,100,000 miles!
I was always amazed of diesel trucks and they are a beuty, they cam last for ever 🎉🎉
Sorry man . Can’t take anymore of this
Please start a 7.3 store! PLEASE PLEASE PLEASE THINK ABOUT THE ISSUES YOU'VE HAD ! THINK ABOUT A Novice looking through this nightmare window of part hunting... ford has now tripled the cost of every single part
Absolutely not, only buy ford parts or don’t own the ford at all
@user-zb5nc5ke2h they don't make half the stuff anymore.. you find it we'll buy it.. 750 bucks for a stock tank switching valve. 86 bucks lifetime warranty
with the key in "run/on", i have 12v, not 5v, at my ipr connection... i havent pulled the ipr out yet to test its coil resistance. assuming there is no such thing as a 12v coil, i will not only have a fried coil, but also will need to figure out why i have 12v to it instead of 5v... wiring harness issue?
Thats good computer just demanding max open no issue here
@@CUSTOMWORKS7.3PSD ok, good. well, at this point then i have narrowed down the potential culprits to; possible bad IPR, possible bad HPOP, or maaaaaaaaybe a weak fuel pump. The fuel bowl does refill, so i dont think that is it (though i dont have a way yet to measure the pressure- looking for a min of 50psi, right?) Next steps are to pull the IPR, test coil resistance and air-flow test, then get a way to accurately measure fuel and oil pressures.
What about glow plugs? I’m surprised you didn’t cover that early in. I have a 99 7.3 and I am having trouble when it’s 20 Fahrenheit.
You missed the injector harness in the valve cover 01
Im New to 7.3 and so far loving the truck. We yesterday i did its 1st oil change as a 3rd owner and clened tge engine bay alitle bit took the truck for a spin. Came back parked it overnight, tryed straing it this AM and cranked but wont start lolo😂😂😂....
It has fuel, new oil and filter but the batteried are dying now lolo....
What could this be 🤔🤔🤔🤔
2000 EXCURSION 7.3
Started misfiring on acceleration for about 5 miles, then just shut off and wouldn't restart. Scanned and got these codes.
P1670 (Electronic feedback signal not detected)
P1280 (ICP Sensor Circuit low)
P0478 (Exhaust pressure control valve high input)
I disconnected ICP, still no start.
The electronic feedback code has me thinking its the PCM however , when i turn the key forward I get the glow plug light and check engine light,
Where should I start?
I for got to put scanner that I found in my previous comment

Maybe you can help me. I have a 2000 7.3 diesel dually truck. I just want to give you a list of things I've done and still no start. Fuel pumps been changed. High pressure pump been changed. All sensors have been changed with OEM sensors. Pcm and IDM I have been checked. . All fuses are good. Any other ideas would be really appreciated
I'm at my wits end with the starting issue I'm dealing with on my 01 7.3 that was gifted to me by my brother, so it's sentimental and I WILL get it running. But any input would be great! I'm pretty capable but diagnosing this issue is beyond me.. I just changed the solenoid on the fire wall and got a few cranks, but then right back to a single click when turning the key. Bad ground? Frying these solenoids ? Idk. Anyone with any experience with this. I would really appreciate it
Thanks for another great video. I fought through many issues with the hard/no start. The starter just sounded weak. A new starter, powermaster, did the trick. The truck started an ran well. BUT about 2 weeks later; Got in, turned the key, all the lights illuminated, normal, Turned to start and nothing, everything went dark. Any suggestions?
Man, where have you been all my life!!
Absolutely love the delivery, and I love to learn. Pulled out my fuses 1 at a time, checked them and put them back in, because I couldn’t figure out which fuse controlled my mileage and temperature gauge. Truck hasn’t started since!! I’m just going to change out the sensors, change the filters and oil, and clean up the engine !! I’m not sure the original owner ever lifted the hood.
I needed this video
Thank You
Just wanna you are very very very smart guy , love your videos and I just bought a used 2003 f350 7.3. Not running of course is how I get such a steep discount of 2k to buy it And hopefully soon be running strong with all your info. I have personally wrote down your punch list.
Thank you !! For a very very good video and many more I’m going to watch.
Thank you again !!
From Shawn ❤
mornin,
recently i installed a new hpop on my 2001 f250 7.3 and bew valve cover gaskets,it seems the truck idles a little faster but the main problem is after driving it and shutting of for maybe 2 hrs when i hit the key it spins over like it will start but and after doing this a while it;ll start last nite this happened and i just happened to put my ful pedal down a little and it fired right up. im confused
Issue I’m running into 2003 7.3 always runs wonderfully started at one morning idling nice and smooth and just shut off. Cannot get it to restart and have it invested a lot of time and diagnosis other than the obvious position sensor change no good plug the sensor on the right fuel no start still just have not had time to diagnose when it’s spinning no smoke or anything of that nature no white smoke just wondering Place to go next for diagnosis
Wow. Great experience and information on the 7.3. Much appreciate you producing this series!
Hydrolic compression has nothing to do with oil life. It's contamination from the combustion blow by that breaks it down.
I ran out of fuel one day on the road and it died on me come to find out the gas line from the fuel sector disconnected itself and now it doesn’t want to start. Already leaked the air from the gas bowl any advice on what it could be? It did shake pretty bad in first gear jumping and what not before I ran out of diesel on the road.
when changing injectors cup and injector is it imperative to change the oil and filter
Typically a good idea but not "necessary". Just replace what oil you lost when removing all the injectors.
I bought a 97 that supposedly ran out of fuel and sat for many years as it was running and died, started back up and went a block and never ran again. When I got it. I put new batteries in it, was cranking it over to get fuel up and the IDM blew up so I bought another one, ran the scanner on it and the injectors cycled. The hvop reservoir was empty so I filled it up and it drained immediately, I'm not getting oil into reservoir from lpop even after cranking several times, haven't checked the check valve yet but suspect injectors might need rebuilt one I get oil into the hvop. Your videos are a great source of information as I'm an ASE Master tech, not real familiar with the 7.3 other than is over built for passenger trucks. Mine has 275000 miles on it and going to get a million more out of it.
How can the fuel bowl heater make it not start? Mines been disconnected for some time now and has always started and ran without it connected. Maybe thats my issue now?
Dónde consigo el scaner obd2
Don’t jump the coolant temp sensor. Did that today. Fried my pcm today.
Super curious that you address the LPOP for a fraction of a second and move on.
I have enjoyed your videos, very informational ! You say the engine wire harness should be replaced under normal maintenance . Where do I find a new harness? Ford says they are obsolete! I have a 2000 E350 7.3 powerstroke.
Were you able to find someone who sells the harness, like you said Ford has stoped making them anymore
My old 95 e-350 7.3 died as i came to a near stop to make a turn. Started right back up. IPR has about 50,000 miles on it. I remember from past research my problem could be the crank position sensor. Do you agree? Thanks so much.

I have a 99 7.3 4 x 4 the engine is stuck won’t turn over I pulled the glow plugs thinking it might be hydro locked but it is not. I think the condensation accumulated in the cylinders over the course of five years not being run. And rusted the rings. I’m now soaking the cylinders, but it just doesn’t seem like that’s the problem either. Is there something I should be checking before I continue going down a rabbit hole?
Thanks
If the engine turns with the glow plugs out off the crank with a ratchet Then I have run into trucks I have had stored for years , starter went to rust , connection at the starter bad , transmission torque converter stuck or clutch , Injector stuck contacting the solenoid do a buzz test (FORSCAN app via your phone)
He is right. I've been a diesel mech for 30plus yrs.
Thanks always helps getting a boost from a pro like you !
@@CUSTOMWORKS7.3PSDwelcome sir.
For something like an ICP or alternator, I actually go with a parts store part with a lifetime warranty. Only because I can pull in and swap it in a few minutes and if there is an issue I can unplug the ICP and get to the store.
2 years ago I ran TS6 chip with custom tunes for my BTS transmission. Which made it a completely better truck. But I had a problem with it on a intermittent issue which felt like dropping 1/2 the cylinders.
I had previously had the L. Valve cover off and fixed a bad plug connection so I was familiar with that issue. Being in south texas for the winter I found a old farm shop that was able to read the 7.3 codes. It took a while but after removing the chip the problem was gone along with the needed HP to pull our 5th wheel.
BTS programed a new chip and sent it to me at no charge .
Before heading south i decided to replace the valve cover gaskets and wire harness this year . Even though the truck was running good . The harness plug was loose under the R. valve . And also replaced the glow plugs. Money well spent.
You talked about replace all the sensors, I wish some reputable business had a package with all the sensors at a reasonable price. I've replaced the ICP sensor so I know they are expensive.
On a 01 7.3 ,186k miles.
Thanks again for the great info.
Mine started out acting like it was running out of fuel. Made it home changed the fuel filter and it ran great, drove it around for a couple hours with no issues. 2 days later started the truck made it about a mile and it died, towed it home. Now it starts but only runs for about 15 second, if I touch the fuel peddle it dies instantly. Drained the fuel housing looked like it had water in the fuel. I treated the fuel and changed the filter a couple of times in between the 15 second runs but I have made zero progress in resolving my issue. Any advise?
I'm not there and trying to diagnosis a issue over a short explanation is very difficult OK,,,, Sounds like the uplift pump
My 7.3 will crank up run like crap and smoke really bad then it will shut off and not fire back up. Any advice
FOCUS ON IPR, ICP, CAM SENSOR, Wires and connector I have video's on all of these also get forscan to do monitoring and diagnosis If those all check out then its a IDM or Injector issue IDM can be monitored with forscan
Where do you get new harnesses? Ford doesn't have any.
What are all your reputable aftermarket part sources as mentioned in video ? Thanks!

Thanks a lot for pointing out the most regular problems and for sharing. Again! I really appreciate these videos.
Hello sir I have a 2001 ford f250 super duty. My problem is the truck only starts when I plug it in. I just dont understand what the problem is. Thank you in advance sir.
I'm not standing in front of your truck OK that issue is usually bad glow plugs or relay or wires associated with that part of the system
@@CUSTOMWORKS7.3PSD thank you sir. I will do glow plugs next. I did replace the relay. But no luck.
What's up with that Gangnam style in back
This channel is so good I'm watching videos about issues I've had in the past and resolved just to see how well he explains it and if I had this video alone a few years ago I could have atleast 10 hours of my life back I wasted trying to compare different videos etc.
I've had my 7.3 since 2013, If you are kinda new to the game there's no need to look any further, this is the best channel .
Very comprehensive video. Old guy with a 1997 F-250 CA emissions, 120 k miles. Never had any expensive problems since 1997. Just crank sensors and (1) IPR change. Had an issue popping up this winter. cut out, no start. Think it was water in fuel issue. Thank You for helping. I'm locked on to your videos.
Did it crank and not turn over?
Why would my 7.3 lose old pressure randomly driven down the road now it will not start
lpop starting to fail, hpop starting to fail, injector seal failing, bad signal or gauge
Quick question, will my 7.3L start with the turbo pipe off the compressor side of the turbo? Will they run or start with one or both of the down pipes off?
Yes
@CUSTOMWORKS7.3PSD thank you, I just Rebuilt the injectors and can not get it to start for nothing, I followed every singke step in all your instructions, even pissed off the ol lady using her new shop vacuum LOL. I watched every singke one of your injector videos, and more, I've checked voltages, harness, everything, am at about a total loss of possibilities 💔💔💔😢😢💔. It won't even kick with small shot of starting fluid, other than a small back fire when I tried that. Now just small white cloudy smoke perse, that I think is only un-burnt diesel fuel
Perhaps the CPS took a crap on me? Going to pick up a new one today. What are chances of that happening? I'll look at my RPM gauge before I go spend $70 on new one. I replaced the one in it last beginning of Fall or Hunt season.
I have a 7.3 in a bus I got to travel in
Hey. Great videos!! Can you please list a sample of “reputable diesel site” sources for wiring harness and other parts?
I'm doing a video on this as soon as I get some commitment to quality back from the builders for now always yake a look at riff raff good company
From what I’ve seen you’re one of the most knowledgeable PSD people I’ve come across. I’m at a loss for things to check I have a 2000/7.3 that was removed to repair a broken bolt in the water pump, don’t ask I didn’t uninstall the engine I can’t get the engine to start I did all your checks and no start. New fuel pump & batteries glow plugs ok oil in HPOP IPC IS New disconnected still no start I have no scanner to check HPOP out put. Is it possible the LPOP lost its prime and can I remove the OP sending unit and pump oil in to prime the oil pump. Also the starter seems not to crank as fast as the videos I’ve watched. I’d hate to replace the IPM if it’s not bad. I’m an GM wrench and worked on many GM Diesels I rebuilt many standing injection pumps I’m pretty handy with a wrench and hate to replace parts not needed but I’m at my whits end any suggestions would be appreciated also I disconnected glow plugs and tried WD40 we started GM diesels with WD and tried some either and it doesn’t even fire I’m lost can you advise. To dalebowling4@gmail. com
How much oil should come out of the ICP sensor when you hit the starter? Mine overflows but does not shoot out by any means
should shoot out at 500 psi like a 2 second crank would be several quarts
@@CUSTOMWORKS7.3PSD
Thanks for the response. I guess my IPR is bad even though it has just been replaced by a mechanic before i bought the old girl

Thanks so much for your 7.3 videos! I’m experiencing a problem with mine that has me baffled. This is a 2002 model f450 with only 5800 miles. Obviously bin sitting much of its life. The problem is when cranking for start hpop doesn’t build for 6 to 8 seconds. According to the scan gauge I have connected. Will the ipr pid today too determine its position through this scenario. This is regardless of ambient or engine temp. It then builds pressure starts and runs normally . The crank rpm seems normal. I checked the oil level in the reserve chamber and it remains full. Would a ipr or hpo sensor cause this problem? They are next on my list but I wanted to check first before throwing additional parts at it. Btw the oil is fresh 15/40.
Thanks
I wanted to get the scanner you listed but was having trouble finding it
here is one I found that is wired which is fine for me to my laptop
WILL it do all that the model you recommended???
I haven't ever asked a question on TH-cam.

Great video as usual thanks for the info God bless
I have a question for you sir, I am fighting a crank no start with a constant check engine light. At the end of the buzz test the SES light turns off until the key is recycled. What can this be an indication of? I do not have rpm on dash and have verified continuity with cps, and pcm to IDM. New IDM as well
Bypassed the IPR and truck started but not smoothly, Saw in akother video the same thing started the truck, After the guy replaced the harness it cleared up, would you recommend an aftermarket wire harness that's not as expensive as oem?
This 30 minute video has 100 of hours of 7.3 powerstroke knowledge it you own one you should know this stuff
You didn’t mention the jumped up voltage in the IDM it could be a really shocking problem..
Non functional fuel bowl heater will stop your truck dead in its tracks??

Hey Clint, is there anyway for the check ball held under the non serviceable plug to go if it is lost in the pump ?
Clint, I'm a diesel tech, my shop sells Stanadyne fuel supplements and I highly recommend that product.
