2003 early 04 Ford 6.0 Powerstroke diesel no start 

Rest in peace Ron, you were such a great man I've learned a ton from you, blessings for your family!

RIP Ron. I own my own shop now and I still revert back to your videos.

I hope his family is still using his tools he helps so many people even after all these years

No one can match dieseltechron RIP dieselGOD

Wish you were still here to help the 6.0 community. I seem to revert to these videos for so much on my 2003 6.0

RIP Ron! I am sure there is diesel engines where you are now. Thank you for all the wonderful videos.

RIP Ron your videos still helping me today thanks brother.

Thank you for your videos and your legacy. RIP Ron.

Fountain of knowledge, glad he left a legacy.

such a legend, full of useful knowledge

03 early 04 are on the top rear like in the video. 04 and up is the three wire sensor on the passenger side valve cover. Using a scan gauge 11 is the easiest and least expensive way to diagnose and monitor stuff on these.

DieselTechRon. Don't pay any attention to the naysayers. The video is great. Thank you so very much for sharing your knowledge, experience and tips. Your videos are most appreciated. Keep up the good work.

okay. I know I should not take some things to serious. But how can I have three thumbs down on this video? I'm giving free info and trying to help. If I'm wrong that is what the comment section is for. Educate me so others can learn from my mistake.

Merry Christmas Ron!

Ron...trying to help my son in the AirForce fix his 03 6.0 and we had a similar issue but I think HPOP and ICP sensors are ok. Here is history: had been rough starting when cold for a number of months but ran well once started and for rest of day. Put on ScanGauge -- all normal except for 29F diff between coolant and oil temps. While ordering parts, suddenly started blowing white smoke -- also threw ICP code. Took out of service, then changed (using ford parts), ICP sensor, IPR screen (although it was clean), oil cooler, EGR cooler, EGR valve and HPOP screen. MADE MISTAKE OF NOT PRIMING HPOP OR COOLER - OTHER THAN TO ADD OIL TO OIL FILTER HOUSING. Would not start - noticed little oil pressure on dummy gauge (low side). Figured out that stand pipe in oil filter housing had been missing spring since we had truck. Changed standpipe -- confirmed correct housing top and used Motorcraft filter. Tried to start again with jumping vehicle -- now had good low pressure oil but still wouldn't start. ICP at 1600, IPR at 45%, FICM 48V, CAM and CKP sync ok. Really would be very appreciative of your advice. Could we have too many bad glow plugs (remember was very hard starting cold to begin with) or a bad glow plug relay... or do you suspect the HPOP or something else? Again -- you are the best and we could really use some tips. THANKS!!

I just posted a video on a rev-x case study. The heater control unit is the most common to fail.

No priming of the pump. Check for restriction in the fuel system. Possible in the tank ESP if its a 450-550 with a rear tank. Install the blue spring kit. Is the crank even? (Compression) try a know good ficm but injectors are the most common. Any codes?

your the man!!! great info. thx bro.!!

Hi there Ron, hope you had a good holiday. I have a early 03' 6l psd crank no start. I got a scangauge2 and it worked great. No i am gping to start air testing for leaks. My questions is do i have to energize the ipr diring the air test with 12v i have wached a lot of you vids on youtube an i dont see you doing it. Yet in some vids of other guys they jimmy rig power to the ipr. What it correct method? Many thanks in advance Matt.

good video amigo

That is a lot of labor ...I enjoy your videos and the detail you put into explaining what your doing and why...question....I thought when you replaced an aluminum early 04/ 03 pump,you replaced it with a cast iron pump like the newer trucks have...

Hi Ron. Happy holidays to you just wanna know if the new pump needs. To be prime. And how is it done ?? Thanks

I just took out the tube/pipe next to the pump, there is an o ring inside and a spring type that is a bit loose in its housing and also its cut, is it normal? also Im trying to figure out if I should replace the pump as I have a no start (just like the one on the video). I can see the ball on the side other than that I don't know what to look for if the pump is bad. Any Ideias? I replaced both ICP and IPR. Thanks

Yet another great video Ron!! Good job!! Oh and btw, I got a 06 6.0 with sticky injectors.. What's your feeling on the rev x?? Everyone I've heard says it fixes the problem but does it really or is it just masking the problem??

R.I.P Ron

ron, i have an early 2004 powerstroke, it starts great when cold but when its at operating temperature it starts hard and barely runs for about 5 seconds then comes out of it and is good to go. what should i be looking for?

Ron, the last video you uploaded concerning the doorman oil coolers. I did an EGR Delete back in 2011. I had bought the kit from Performance Machine in Lenoir, TN. After about 18 months I had a problem with the truck. Took it to the dealer and they said the oil system was contaminated with gasket materiel. Got truck back home bought OEM parts from Ford and redid all the work I did back in 2011. Sure enough the gasket for the il cooler housing was breaking down clogging up everything. I now only use OEM parts for my F-250.

Ron, my 2003 6.0 runs rough and the acts like it runs out of fuel and shuts off. Ficm voltages are good. Compression good. Icp and ipr show good. Fuel pressure koeo bounces between 35 and 45 psi. I changed the electric pump. Cylinder contribution shows #7 not firing. Self test were all ok. Any ideas? Will a bad injector allow the engine to run out of fuel?

Hi Ron, I Have early 2004 6.0 engine. What is the Normal operating range for ICP%, EBP and IPR psi during idle speed? Thank you. Yuriy

how long does it take to start afterwards? just replaced hpop and ipr on a work truck.

The tube that goes from the pump to the main branch tube....you mention replacing it because the seal leaks. Can you just replace the seal? Where can the leak be noticed?

Ron, I have a 03.5 that shuts off while driving. It take about 25 minutes of drive time then shuts off. Give it about a 1/2 hour then it fires back up. I've disconnected the icp sensor and still won't fire up until it wants to. It seems like it has to cool down then its fine. When it's running all the sensors you say need to be right are ok but when it won't start the ipr and icp are not. I'm lost

hey jc Winn I have the same exact problem as u. I cleaned my turbo replaced all injector o rings and copper washers replaced ipr screen cleaned egr valve checked all cac tube for leaks pulled fuel pick up screen won't rev past 1100 rpms started out like yours gradually got worse icp builds pressure but ipr goes to 85 when I hit the pedal and I get 1100 rpms max. will not even try to rev up in drive or reverse. did u ever figure out what was wrong with yours? ficms got 48 volts to. I don't know at this point

Ron, what is the SW you are using how can i get it? and what is the hookup for it? wifi? bluetooth?

hey Ron I got an 04 6.0 she blew a ton of white smoke on the highway then shut me down. when I towed her home the coolant was empty. I replaced the throttle sensor that was broken and cleaned the egr valve and filled coolant. now she will start with a boost and run for a minute while blowing white smoke then shut down any clue? the heads have been planed and studded last year.

Hi Ron, I'm looking for some clarification before I dive into my 6.0. I have an 03 6.0 that is having a no start when hot, and a hard start when it's been sitting for a while. It is acting just like an SCT or dummy plug issue, because it takes a long time to build pressure and it can't build pressure when the oil is thin and hot. But my understanding is it doesn't have SCT fittings or dummy plugs. If the ICP was messed up I wouldn't be able to start it at all, right? Where should I look for a slow leak on an 03 that has the same symptoms as an SCT or a dummy plug? Thank you so much for your help and your comprehensive videos. You have already helped me chase down electrical gremlins on my F250.

Hi Ron and thanks for your awesome advice! I have a March built 03 6.0 and have recently had a problem where the the truck would start ok, but while driving I noticed the the transmission was kind of surging or hunting for the right gear, no matter how much I added throttle. I checked the ICP and there was oil inside the sensor, so I swapped it out with an after marked ICP sensor. After deleting the codes, it fired right up and ran like a dream! Next day I took it for a ride, it was hunting for 2nd or 3rd gear again but after the engine/transmission was warm it ran perfectly! The next day it wouldn't start at all! I noticed a bent pin on the ICP sensor and straightened it our and cleared the codes and again, ran like a dream! Now, I'm having the same symptoms where the tranny doesn't want to shift into 2nd gear when cold and it starts kind of unwillingly but eventually idles fine. Transmission shifts in all gears fine after about 15 minutes of driving! No check engine light or codes either.

Be great if you could show how to pressure test the HPO system on an 03 6.0. I just had a new HPOP put on 7k miles ago and now same symptoms, crank no start. IPR 85%, Ficm sync and power all good, ICP making 5-600 initially, then bounces around to 250-450 psi never getting back to 500. IPR screen good, clean, no trash. Broke two wobbles trying to remove IPR valve. They may not have replaced the tube when they did the HPOP, no way to know. When disconnecting ICP to default, ECU shows 1700 psi IPR 50%, still no start when trying to bypass ICP. They may have even used wrong oring on top of HPOP. There Has to be an oil leak, maybe injector oring, but not sure how to test for one. Hard to believe pump has failed again so soon.

Where is the icp sensor for a later 04 located I had to crank my truck 3 times before it finally turned over hoping I don't need a new ficm

hey ron 2005 larait the HVAC control center, works somethimes and other times doesnt work, you gotta shut the truck down then restart it for it to sometimes come back, and the autohead lights went also wont work, youjust just turn the dial and it works, but any idea whats going on?

hi Ron, I've been having a cold start on a 04, the truck will not start in till the motor is at 80 degrees , we believe something is corrupting the signal to the cam sensor , we have changed many parts , injectors, cam sensor , ficm, fuel pump, regulator, oil pump, engine wiring harness, have you ever found anything like this ? thanks richie

I'm an idiot. I cannot locate the heat shield protecting the icp sensor. I feel like it's right in front of my face. I see the turbo, back of the block, driver's side. I just can't find anything held together by three bolts. How far up is the shield?

where do you buy the tube for that oil pump?

Very Good!..

hi I'm Melvin I have a 05 ford f350 6.0 do you know why my turbo is not boosting at all the truck start and run but 0%boosting on my turbo please help me

I have a 03 6.0 that is a crank no start. that has no sync, icp is 0 and ipr is 85. engine is dragging during crank. ficm is holding around 47-48. not sure what can cause all of that.

Just had a no start on my 06 it was missing o ring on back passenger standpipe

Hi Ron, I was hoping to get your opinion on what was happening as the following scenario played out on my early 03 Ford Powerstroke 6.0L. At first I noticed that each time I would start the truck it was having to crank slightly longer before it would start. After three or four days my wife came home and told me it didn't feel right. I drove it to work that day which is 22 miles. After about 15 miles I noticed a substantial loss of power which quickly got to then point that getting to 55 mph was all I could get as I reached my off ramp. As I took off when the light changed it was almost as if the pedal wasn't connected to anything. Luckily I only had about a mile to go and struggled to get to 35 mph. As I pulled into the parking lot it quit running and I coasted into a parking stall. It would not start back up so I left it until after work at which time it started right up. It still had no power and would only hit 55. I was hoping I could limp it home but when I got to just a very slight uphill grade it got slower and slower until I just pulled over and called AAA. I got a P2290 code and started searching youtube which is how I found your channel. I bought an OBD II dongle and the Torque Pro app for my phone and while setting it up I got the truck to restart but after about 5 minutes it died. I didn't have Torque Pro set up completely at the time but if I recall correctly ICP pressure was at about 450 but would go down as I throttled it and it doesn't bring up the code anymore. I've been watching your videos and they have been very, very helpful especially with the way you not only talk about fixing the problem but take the time to explain the different things that can cause the problem. I've told many others about your channel and they all think it's great. I've learned enough to think that even though the code says, 'Bad ICP sensor' the problem may go deeper than that. I got the ICP out but I don't want to put it back together just to find out I need to take it apart again for something else nor do I have the money to just replace parts that are good. Could you possibly give your educated opinion on what was happening as this failure progressed and your recommendation on how I should proceed from here? I've already removed the FICM and mount, disconnected the three injectors and pulled the ICP sensor. I'm currently looking for an IPR socket and a fitting to do an air leak test.

Ron I have an 03 f350 with 6.0 problem I'm having is no 4x4 when hub in auto position, pump working , I have all heat selections, but no auto 4x4 checked hoses they look good no cracks to be seen what else can I do??? Thank you sir

Okay, I found the heat shield. This is not going to be easy to get off. I only see the middle bolt and I got it off, now I have to find the other two and somehow get them off. It'll all be worth it though

I have 2003 no crank. Ignition switch has been replaced starter has been checked safety neutral switch has been replaced the transmission still not crank

the special tool to remove the oil line. where I'm general can I pick one up and what is it called?

I have an IPR on a 6o is the plug-in supposed to spend

Will a ICP sensor cause a no hot start on a late 03 6.0 mine just started doing

how can you tell if your 6.0 is a ealry 03 and 4?

will it start with a good ipr and bad icp?

my 6.0 cranks and sounds like it wants to start and keeps turning over but it doesn't start

Those aluminum HPOPs have a high failure rate. Use a late model iron pump. Next to zero failures.

I hit a Moose on new year's eve and it smashed my radiators into the fan and destroyed the fan and shroud pretty much everything from the power steering resivor to the Engine coolant expansion tank I have replaced everything and hooked up the batteries and all that happens is some clicking under the dash in the Fuse/ Relay Panel CAN ANYONE HELP ME FIGURE THIS OUT ? THE BATTERIES ARE SUPER ALL ELECTRICAL CONNECTIONS ARE GOOD ALL GROUNDS ARE SOLID I hit the moose pretty hard but not hard enough to set off the airbags COULD THERE BE AN EMERGENCY BREAKER THAT HAS TRIPPED ? I am aware of the Emergency Fuel shut off but if it was just that the engine would at least still crank over if I am not mistaken. HELP Please !

Just replace ALL the O-rings .

Truck has been parked on hill for two months now won’t stay running will turn over but shut rite off
