- With this video I show how I look for and try to isolate why the injection pressure won't build up enough to run the engine.

Rest In Peace Ron, wonderful teacher. with out question the best diesel tech ever.
Still helping people after all these years!!! RIP Ron. You’ll live forever on UA-cam
Ron we miss you! But we will all be joining you!
Miss you! Wish you were still around for your family and to teach us.
I know you’ve moved on to a better place but thank you ron , helped me look like a bad ass when I got my dads truck running after just unplugged the icp censor after my dad bought a new f150 because his 03 7.3 wouldn’t start randomly one morning , love you buddy
Thanks Ron, saved me again. R I P. Buddy
Man you knew all there was about the best truck ever made for the working man thanks Ron for being with us
still using your vids long after finding your channel. RIP buddy!!!!!
RIP Ron, your common sense approach and advanced troubleshooting techniques are the best...
Thanx alot for posting this video. Helped me out when I got stranded with my family and it didn't want to start.
What was your issue?
Excellent video Ron! For those who have a 7.3 without a bunch of mods this type of information helps
R.I.P I learned alot from your videos
We love you Ron. Only new you through your videos but would have loved to have met you in person. Admire your knowledge and the way you taught us. 🙏
Thanks Ron, Your videos have been very helpful. I had a hot long/ no start on my 95 7.3. It ended up being an IPR problem. Thanks again.

The world is not the same without Diesel-Tech-Ron in it!!!
I really appreciate this information, you helped me understand alot more on how to fix/understand my 7.3 no start
If anyone else has this issue, I just got done troubleshooting mine. Wasn't injector orings, hpop, icp or ipr. It was the starter. I was getting 250-350psi icp on warm starts but my rpms were about 150-175. Not enough to create enough oil pressure with the hpop. Replaced the started and it's good to go
Thanks Ron. With your help I repaired my F250 2002 IPR and now it will start when hot and not just shut down on me running down the road. Found the rear O- ring damaged letting pressure by- pass giving me low pressure/no start then hot.
rest in peace great man
I wish I had all those gadgets and the experience he had. I have a crank no start situation and have already eliminated the easy stuff. The garage is probably my only hope.
Still helping out . Thanks for all you left us
That's kinda funny Nathan. I just chased a 99 doing the same thing for a week. Tried a PCM and icp. Same thing with the 3000. Got a used wire loom and installed it. So mine had power feeding back somewhere. Its a pain but you can try an overlay back to the PCM but you would need to know which one is causing it. Remember vref feeds TP CAM ICP and MAP. But also make sure you're not starving for fuel like I show in other videos. Yes I've had bad pcms and ipr cause stalling. Its going to take some
possible fuel or idm even injector shorting out the idm. The jumper eliminates the pcm from controlling the ipr. It closes it so it goes full pressure that it can reach.
Rest In Peace

Hey Ron, I just completed a E-Fuel conversion on my 7.3
I don't have a fuel bowl or pump in the valley of my engine but it's all mounted on the frame, you could swap out the IPR on my truck on 5 mins!
Great video Ron, thank you. Do you possibly have a link or tool number for the block off plug and adapter fitting for the sensor to plug into the high pressure lines?
Another great video Ron. Thank you. What causes this pump to fail? Was this a high mileage engine or do you suspect that the oil wasn't changed often enough?
Still Here With YOU RIP Tech Ron
Heaven must of needed a diesel technician......he's forgotten more than most will ever know!! Keepem stroking!
I miss Ron.
Yes, hey was really a great guy ! R.I.P. Ron
GRACIAS AMIGO ME AYUDO BASTANTE MI 73L SE APAGABA REEMPLACE IPR Y LISTO
What is the tool # for the fittings to dead head the lines?
Rest In Peace Ron just turn my truck on thanks to you
Hi thanks for the video the same think happened with my excursion 02 7.3 it died on me on the freeway I got tired of it so i took it to the dealer and they said it was the hpop high pressure oil pump, ,they said 2200 dollars to fix it I could not believe it .
I've a99 7.3 I drove it in the yard got out usually i have to plug it up for it to start but I didn't plug it up was a week then I tried to start with no success I check fuel pump is pumping I loosen the cap on thefiller bowl I guess in top of the motor now it spray fuel every we're after putit back on an it will only fire off with starting fluid
DieselTechRon: Another question that I had, when you explained and Isolated the HPOP as the faulty component, is the Old HPOP serviceable or would we have to buy a Brand New Pump? Other videos are pointing to the HPOP pressure lines seals as a major oil leak problem and as I noticed on my diesel the Turbo Pedestal seals(underside pedestal to intake) are leaking and I do have some oil sitting on top the Intake which brings about another question? Although, there is some oil leaks, Hpop lines, Turbo pedestal underside seals, Oil Level is within Range and at Mark. Wpuld minimal oil leaks cause my Hpop to fail and have to be replaced or just removed, inspected and new seals? thanx again, if I do hear back from you,..
Thank you Ron. You got ahead of us brother.. rest in peace

RIP DIESEL TECH RON! FANTSTIC AMBASSADOR FOR THE MECHANIC COMMUNITY!
Still learning from you videos keep up your dads helpful vids Cory
Also if I want to look for internal leaks for the hpop how would I go about doing that?
Thanks for the simple and helpful information. I now know I have a starter problem
I think i know more about the 7.3 powerstroke and i don't have one i got the old 7.3 idi non turbo but somebody added a turbo to mine. one of the most reliable ones powerstrokes are not as good for those reasons and the parts do cost more. but the sound i love them for.
Thank for sharing Ron
I have watch all you video and there really great
Do you do also medium truck?
Ford LcF
With ford MD Truck software
Thank
Keep it up good work
I appreciate this video, I hope it helps me when I get back to daily ing my 97 OBS powerstroke
I put 175 Psi in the hpop lines to the heads i do not hear any air leaks. do you think maybe the front seal on the pump is leaking oil into the crank case?
DieselTechRonnie: I know this Video of yurs is almost 2yrs. old now. I am testing the IPR as I have a Crank/No Start situation-2000 Ford F350 Diesel, Powerstroke 7.3L Dually, 2wd, Manual Trans. I unplugged the IPR and getting ready to test with the pigtail wiring harness you suggested. My question, when this pigtail harness is hooked up and plugged into the IPR valve to test, Do You Turn the Ignition Key on as well? or Just apply the 12 volts from the Battery with the Key in "OFF" position. Two New Interstate Batteries, Newer high Torque Starter(4 yrs. ago) New Glow Plugs and Relay Installed, Two New 110 amp alternators and New Fuel Pump/New Fuel Filter Intake Side and I removed and cleaned the fuel tank and the socks then, decided to do a Hutch Mod. and omitting the Tank Filter and added Clean Diesel Fuel. I am a Female, Self Doer, and Know this truck Inside and Out now because of your reliable Expertise!! Thank You! Thank YOU! Please explain the IPR question above more thoroughly(Turn Key on/off with Test? when apply battery voltage) as I don't want to screw any electrical components up and cause an electrical surge or Fry myself! 419-557-4706
I am pulling my hair out with this 95 7.3. It'll start run for a couple of minutes and cut off and wont start again.Im getting about 12psi @ the Schrader valve.I've replaced the fuel and oil pump and ipr and other sensors,new front gas tank,fuel bowl filter,computer tested fine,I'm almost ready to dig a hole and bury it.Any help would be greatly appreciated.
Any luck? I am getting the same sort of issue. Only morning first start. Runs for a second or two then dies. Takes about 3 try's until it stays running. Only happens when left overnight. Fires up fine during the day.
also my oil resivor was full clear up to the top , not a half inch down it was full to the plug surface
I have a p1280. I replaced the sensor a couple years ago. the plug is dry. I'm thinking the sensor is bad again. this led me here.
it runs but it doesn't want to rev up real well with white smoke.
koer throws a p1284. it kicks the test. koer glow plug test won't test either.
though I haven't pulled the covers the plugs are not burnt on the outside. these were replaced when I replaced the go pump 2 years ago.
wires don't look bad. I didn't peel them out though.
thinking I'm gonna throw a senior at it.
I've got a 97 that cranks but won't fire. A friend told me this the first thing I should look at replacing. He said if I unplug the truck should start and this making the sensor bad
I know this is old but could it possibly be the IDM? Ive tried all these 97 F350 7.3
awesome videos, thanks for the help
Hello I have a no start after I changed the high pressure pump and ipr sensor and still well not start . Don't seem the pressure not high to me . I replaced oring on all the injectors still won't start what could it be
sorry to bother, I put new o rings in my hpop and new lines. 2000 7.3 t truck had a no start found a blown fuse maxi number twenty four. replaced fired up, ran for five mins, reved it and it died. No start after that. checked everything could find nothing. finally I noticed on the directions for the new lines and cross over line, it mentioned to discard the springs and check valve under fittings for lines on pump. seems the new fittings are different inner diameter and the springs don't fit in the fittings like on the original. I belive by not changing the springs and valves, that I may have literally torqued the spring down when I installed the oil line fittings. This is a three hose kit with bolt on hoses not snap on. Anyway I checked ipr, looks great , not sticking from what I can tell , I pushed on the piece in the center while spraying with brake fluid and id didn't seem to stick at all and seemed to open and close the ports as I would expect. I did a test on the solenoid for ipr it had an ohm reading of 11.3. I just now removed the spring poppet check valves. Have you ever had a problem like this? any suggestions? my resibour is full, i also removed the icp sensor and turned it over prior to removing spring poppets and it was just barely any oil coming like a half quart max on a long crank with that icp sensor removed. i also ran 12 volts directly to ipr and turned over no start. My theory is i basically dead headed the pump by bolting down those fittings with the spring poppets in. I haven't attempted re start yeti thought i would attempt to confer with you first . thanks a lot
Still coming through for us!
Recently purchased a not running 2003 Excursion 7.3 same problem
Thanks good pointers Ron!!!
Hello Ron great videos. I am a technician in texas and have learned a lot from your videos really good information. Thank you very much! you show two tools for capping off hi pressure pump on 7.3 could you tell me if you know of any place that sells those tools?
i have a 95 power stroke that will not start. I gave it ether to get it home but just cranks now. Batteries are good, oil level good, fuel bowl fills when cranking, oil pressure is good, glow plug relay was replaced, cps was replaced, fuel and air filters were replaced. Its throwing 3 codes as followed : P0344 cps circuit intermittent, P0470 Exhaust pressure sensor circuit malfunction, and P0603 internal control module jam error. From what I understand none of these codes should be the reason the truck cranks but it doesn't start. Do you have any suggestions as to where I should go from here? @DieselTechRon
replaced my pump, it started up find bt still leaked... ended up replacing the "common" o ring and now it cranks and cranks and cranks.... reads 100 for the pressure and wont turn over. wouldnt think it would be my ipr sensor??? could it be that all of a sudden? i hope to god i didnt lose that little steel check ball in the pump i had it out on a rag and didnt see anything fall out so i dont know what it could be now?
Ok. I got a 2002 F-350 7.3L and when it gets down below 15 degrees it cranks and then cuts off, and when at an even lower of a temperature and plugged in, it still does that. Most certain I'm leaking oil from my ipr valve. Would that cause it to have trouble to start in the cold? It's leaking oil onto the starter and it looks pretty corroded to.
So my icp is bad when its unplugged it starts but when its plugged in it will not start. Is it ok for me to just have it unplugged until I can get a new one? and I know this is stupid but if I have the ICP unplugged will this make the check engine light come on? ( code readers can't find any codes)
Hi Ron, please help me. I'm working on a 2002 F-450 7.3 with No start. I add 15\40 oil to Hpop and it keeps going emt. and the oil goes to the crank case??? Whats leaking? I do not have the block off caps for the hpop lines, If I take off the valve covers on both side where would I see a leak?
My 1996 7.3 psd with 250k miles. Stock. Have a intermittent crank no start problem. My scangauge shows ICP=0 when cranking. IPR 14.8 at key ON. it has no oil on the stock ICP sensor connector. When it doess start it has good ICP and IPR Readings but can have a rough idle with the Engine shaking a bit. the sensors are so expensive and take several weeks to ship to my country so i don´t know if i should order a ICP or IPR... I have a spare CPS sensor but i don´t Think it´s a bad CPS. Shows no CEL or No codes. Passes injector Buzz test.
Excellent work Ron
the used wire loom, was it the whole "master wiring harness" that has the icp, ipr, fuel bowl heater ect. connectors? and replacing that solved the problem? I also dont have any white smoke while cranking but fuel bowl fills up very quickly. The whole no start is likely to do with the wire loom correct? Thanks!
Can the oil leak down in to the crank case from the Hpop or it has to be the heads?
Also if I wanted to look for internal leaks on the HPOP how would I go about doing that?
I have a 2003 f250 diesel was driving down the road and started chugging thought i was out of fuel went got 3gal put it in started up drove a couple miles stop drove few miles home and died before i got home codes read p2614 p2617 p2290 and p1000 what to do?
My 2004 powerstroke f250 i was driving it over the weekend and sudenly it just died. I have a computer and told me low fuel pressure. I did talk to a mechanic and told me it would cost me at least $5000 to fix it. kind of pissed off that a American truck with such expensive parts.
03 7.3l - Would a weak pump cause long crank times to start at any temp?
I have a 97 powerstroke it loops on warm start, sometimes once, sometimes multiply times, just wondering if you had any ideas? thanks
ideas? If you're lucky it's just the icp sensor. Check for a leak into the connection. If you're unlucky it's sticking injectors and it's ramping the ipr back and forth trying to get it right.
I have a question.I have a 99 7.3 Ford every time I drive it in the rain it turns off and when I turn it back on it runs fine do you know how to fix this problem?
Ron, I have a 99 f-450 crank, no start. replaced IDM ran for a few hours and stalled out doing 65 down the highway... Replaced ipr and connector, with scangauge ICP reads high (3000 or so) even when unplugged. On my f-250 (that runs good) when the icp is unplugged it reads in the 700's like it should. Does this mean the pcm is acting up? any help would be greatly appreciated.
Good video. Ron, you are DEAD ON buddy!!! Thanks
Big Boi oof poor choice of words man.
I have a 99 f350 started and ran 3 minutes died glow plug fuse blew unplugged glow plugs still blows fuse. don't know what to do to fix the truck
Shorted.
R I p old boy you is the best
1997 F 350 7.3 will not start after it’s been running. I started out with the replacement of the fuel pump, IPR replacement, IDM replacement, new starter, HPOP replacement, new batteries (2) and still no better off now help
Other items that I have replaced in the last year all new injectors, PCM, ICP, CPI, EBP Exhaust pressure regulator
Did u ever get it fixed
Best tutorial ever
Icp sensor? What it does?
Cool
What was the problem 🫠🫠🫠
Hey i have 2004 f350 new pressure pump icp and ipr still wont star.i don't know what else to do.can you help me please
Lopez Aguilar hey bud did you get it fixed?
Do you have any codes?
hey mate im from Australia and im having troubles starting back up once the truck sits for a few hours. i did what you said about putting 12vs to the ipr valve and after a wile of cranking it starts. what does this mean
Bit of a late response, sorry. DieselTechRon passed away about 9 months ago, but your issue sounds like a fuel leak, he has a video somewhere on it. Basically, a line somewhere is letting air in, which lets the fuel drain out of the fuel lines, back into the fuel tank.
good information, Thanks
hay Ron I have a 03 f450 6.0 I have replaced all injector all new hpop Orings and hpop also a new low pressure pump and when truck is cold I starts with ease when hot no start but cranks over let sit for 10 minutes it will start right up also put new ipr and I Icp sensors I'm now lost I've also put a new ficm please help I'm almost over this ford
Ron passed away in a car wreck spring of '16. You'll have to rely on others on here for advice.
James Porter damn shame too. Guy had a way of explaining things, usually you'd have to pay money for.. information is priceless.
Hi, got a question to diesel mechanics.
I have 2001 Ford e350 7.3 diesel cranks wont start.
It started during the travelling on the road. I drop gas pedal and cruise, and battery and fuel gauges start glitching, go to min and back to normal few times, looks like wire short somewhere and if i push gas pedal again and gain speed it all goes to normal, all gauges go back to normal. It was on running engine. As soon as i stopped it it wont start again and i towed it home.
I'd like to bring it back to life by myself as i dont have other options.
I heard about AutoEnguinity OBD Scan Tool, can I do all necessary diagnostics with this Scanner and find the problem? I found one on eBay for $30 (AutoEnginuity OBDII OBD2 Windows Scan Tool Scanner(USB))
Thanks
Alex
P.S. Thanks Ron, R.I.P Man
Alex Metelkin that sounds like a wiring issue or pcm issue bud
do you think i need a lpop?
I found it. :) had to replace the oil filter housing and know it starts, But no power :(
1 1/8” or 29 mm “Axle Nut Socket” is deep enough for the IPR removal. A standard deep impact is too short.
I got a 96 7.3 f250. all it does is turn over with no start. it makes a clicking noise while turning over and smoke comes out from the intake. all my fuses are good and I put new diesel in the tank. can you help me?
Yes but you need to give me something to go on. icp voltage, pressure,ipr percent, rpm? I have a video actually a couple showing the 7.3 diag
Did u get this fix Jack . What was the problem I'm having the same problem
i have a 7.3 02 130k wont start replaced orings, turbo is leaking and white smoke out of tailpipe, runs 5 secs then dies and wont start any ideas thanks
White is usually low compression.
Hey what is the most likely cause for air in the fuel system on a 2000 7.3
Bad injector seals forcing compression into fuel system. More common on 6.0
we have a "99" f550 7.3 will only run for 13 minutes and then cuts off. we have change pick up in the tank, fuel pump in the rail, new gas pedal.
we disconnect fuel line from fuel filter housing after it cuts off but no fuel comes out until key is cycled again.
I replaced the ipr valve when mine was doing the same thing and it was like new after that
I've got an 2000 F350 dually, 7.3L turbo diesel. the only way it'll start is if I pump the throttle, the motor drags like a bad battery until fuel gets down into the cylinders, then it turns over easily(well a lot better). if it's hot I have to do the same thing. even if I start it and turn it back off then try to restart, still have to pump the pedal.
I've checked both fuses and they are good, fuel pump on the rail is running. I even unplugged the plug at the top of the pedal and it'll start, but only if I pump the pedal, after starting the throttle has no response.
any ideas as what I could check next and if so is there a test for it?
oh, it's not throwing any codes and it has a small hesitation while driving, but clears when given more throttle.
thanks for any reply.
Chris Mcclard I have the same problem
conner shepherd, a friend of mine told me to check the lift pump or lift gate, (can't remember what he said it was called) after double checking with him today I'll see if i can find some videos on it to see is that's the problem. if I can't test it, I'll just buy one and see if that's the fix. I'll let you know what I find out in the next week or so. I need my dually at the end of November for a road trip, so I've gotta get this tracked down. I've left a bunch of post like the one you seen above, but I've got no response from any of the guys. I feel this guy is the best in the business, thats why I wish he would respond. lol
Chris what was your problem? were you able to figure it out?
still haven't been able to get the lift pump off to see, now me truck won't even turn over. back to the basics for me now.
Chris Mcclard I have the exact same situation have you figured it out?
ok, my truck just suddenly died on me and won't even crank. the normal dash lights come on when you turn the key on though. Any suggestions what might be the problem?
Not without info. Try jumping the starter solenoid to see if it's a starter or engine problem. If not use a 15/16 socket. Test for codes. Remove the belt, does it click even like the starter is engaging?
Awwww bad bad deal, i crawled underneath the truck n lo n behold parts of the wiring were wrapped around the main drive shaft
Lol ya done that many time good tool I clip and save all the 7.3 inj conn.
I have a 1993 ford e350 cutaway 7.3 diesel engine the problem I have is that it cranks but it will not start
check the crankshaft sensor is goes on front of the fly wheel is about 25 to 40 dollars
I have the problem crank no start replace the fuel filter cus think was duty , replace one battery autoparts guy told me that was my problem still same after took to the mechanic I'll pay 1.30 dollars for diagnostic show 4 different causes decide to go for the cheap one fix my problem crankshaft position sensor so happy now f250 diesel finally is running good luck people.....
