2014 dodge ram truck drove fine last night, this morning after temps were -4 all night this morning it started up fine normal cold start rough idle. After letting it run for 10 mins I went on a drive 5 minutes into the drive I noticed bogging and power struggle when starting out and it threw code p0087(low rail pressure) could this be gelled fuel causing this issue ? I was confused due to truck starting with no issue but I’m at a loss. Also ran scanner and fuel pressure control 1 which I’m assuming is fuel regulator said it was CL any idea ?

Very well presented! Lots more to learn on my end! Thank you!

i have a 2019 6.7 dodge ram came to the shop with broken low pressure hose.,replace hose and lift pump and high pressure pump i went back to cp3 problem i have is no high pressure coming out of cp3 got diesel coming in no diesel coming out got a low pressure code we have done anything with no luck please help. crank no start

Please advise lm wanting to ask l want to delete exhaust going back in to engine. Mike Newcastle Australia

2017 f260 I have this code p008a showing low fuel pressure on cold morning start 5f two times already no cel truck runs fine is it possible it’s gelled up fuel? It only happens on cold engine on start up, I did check pressure with forscan and showed 55psi on idle

Good Morning Tony, do you have a email address? I have a couple of questions

Yes . Oil change every 6000km , Oil bypass, delete, and install different thermostat. Fuel filter with extra filter

On the 6.7 diagram you have the upper fuel filter ID’d as the secondary fuel pump.

What brand of additive do you use, I use Howes, at 2 oz per 5 gallons.

I learn so much from these videos! Thank you!

Dave you have taught me so much 🤗and thank you for the Christmas greeting you and your wife ☦️ very sweet Dave

I've noticed when i change my fuel filters on my baby dmax colorado the primer pump for recharging the fuel system with fuel and removing the air in the system seems to take forever if i don't have a full tank of gas. when the tank is full it takes a lot less time to purge the system.

Dave’s automotive had a 6.7 powerstroke almost make a million miles and his cp4 pump was pristine! There’s definitely truth to the lubricity factor!

Thank you Tony. In my opinion, technicians should be required to become licensed, not just ASE certification. Too many scrubs in the auto mechanics world, here in the USA. Lazy mechanics who don't want to learn, test, and properly diagnose. So many want the easy fixes without putting in the work of learning system operations, analyzing data, testing techniques, and diagnostic tooling investment. Sadly, too many of these people are working on $30k to $90k vehicles.

Good Talk, enjoyed it. Happy New Year

Thank you Tony for the information without the sales pitch for products we may or may not need!

HAPPY NEW YEAR,Diesel Talk with TONY SALAS 👍 From Nick Ayivor from London England UK 🇬🇧 ⏰️ 23:39pm Good Evening

Happy new year and be happy!!

Great information, thank you!

thanks tony. the cp4 issue is a interesting topic.

Hello Tony

I’d say a perfect practice run Tony !! Thank you so very much for your generosity of sharing your knowledge and experience!! It is greatly appreciated!! Happy, healthy New Year to you and your family!! 😊

I am an Ag Teacher, mainly Ag Mechanics, I have a random problem that started a year ago with my 2016 6.7L. Truck has 135k and has Lucas fuel treatment every 3rd tank of fuel if not sooner. When on a trip longer than an hour, pulling or not, but mainly when pulling a trailer, the engine would momentarily cut out "cough", but never triggered a CEL code. Started in Dec of 23 and did it 6 or 7 times to April of 24. I don't daily drive the truck a lot at the present. We mainly use it for pulling ranch equipment or when I have to use my truck to haul students show animals and projects. The last time it "coughed" it did it hard about 4 times consecutively. I pulled off at the next exit and shut down the truck and found the engine had more oil in it than it should. So I did an oil change in the parking lot of Bass Pro Shops. I captured 3.5 gallons of oil and diesel. Fuel has to be entering through the pump shaft seal as the truck does not smoke, has never been allowed to short cycle a regen, and runs perfectly otherwise. The engine was 2500 miles on that oil change from December. Took it easy on the way to our destination, and it "coughed" 2 more times. Checked the oil and it was not significantly higher. Ran the truck to a local shop, they kept it a week and couldn't get it to act up. Picked the truck up and had it "cough" on the way to my ranch about 2 months later. Dropped it off at another shop out there and they had the truck for 3 weeks, could not make the engine duplicate the issue. While there, they pulled the sensor off the CP4 pump to make sure it wasn't failing. No metal found, and nothing present on the pcm. After talking with a former student who is a Diesel Tech he said he had never seen one puke fuel out the CP4 shaft seal without throwing a CEL Code of some kind. Working blind he would replace the fuel pressure relief valve on the drivers fuel rail. I replaced it with an amazon should work part, finally get a code of P228F, scan tool suggested changing the valve or the pressure sensor. So I picked up the pressure sensor from Ford. Still get a P228F Fuel Pressure Regulator 99 Exceeded Learning Limits-Too High. I figure the valve is a reject and will be getting another replacement. When I replaced the valve I also changed the fuel filters. On the wrong side of the primary filter I found a small brown algae worm in the bottom of the inside of the fuel filter. Now I notice that I hear the pump running way more than it should and I know the filter base is all the way home not bleeding air. Should the electric pump have a check valve on the intake line from the tank? If it does and was bad could that cause some or all of this issue? I am meticulous about my trucks mechanical maintenance. I have to be since I have to use it for school trips, hauling show animals and ag mech projects. This is driving me nuts.

Thanks Tony great show 🤗🏋️‍♀️👍🤺☦️

I just replaced every component including a cp3 conversion in a 2020 6.7, and still have low fuel rail pressure... help

Question my 2009 is giving me code P2291 Injector control pressure to low engine cranking and checked my lift pump and getting 24 psi supply to injection pump and return pressure is about 4psi on the test port and no fuses open either. The trucks started and stayed on for 6 seconds and then stalls now it wont start at all, also got the oil pressure icon on too now when cranking but not all the time though any toughs truck has original 21k miles any thoughts?

im a diesel tech myself,found best way for to avoid issues is change one filter at a time -starting the vehicle after changing the lower filter first,then the upper -and ive never had issues on a restart which does include key priming a few times.

Is #10 a secondary filter?if yes what is the location?

If you can hear your pump working then it’s got power correct? Because right now I’m having a crank no start issue and even after doing the whole 30 second on and off thing to purge air from the system I got no fuel in the rear filter , so I’m guessing the lift pump is bad. I can hear it running and it isn’t screaming but no fuel at the rear filter.

Can you help me please whit my truck

How do you see these live or become part of the round table discussions?

Thank You.!

My 2008 surges at idle after it is warmed up. I changed the FRPS and it did not change. Used a FORD part also. ???

Great video I’ll try it tomm. Thanks

Thank you

hey can you do on on the 2022 f350 diesel turbo. can you tell me what brand it is.

What is the use of boost gauge while driving ? Do we need to change driving based on the reading to achieve something?

Thank you so much excellent explanation

Why would my truck be commanding so much it ranges from 70k-90k seen it go up to 130k truck has like 20k-30k and throwing p0087 code

Im having a problem with the pump not shutting off. I'll take the vacuum lines off and put my finger directly on the line going into the pump and it won't kick off

Does the low pressure sensor read high pressure too?cause I got a P0088 code

Hey Mr. Tony, took a couple of ur ADS classes in West Memphis on 6.0 and 6.4 years ago lol great classes and instructor. I know the vanes and act. Are doing the magic but we have a customer that insist that his engine brake is not working as aggressively. Do u have a video on exhaust brake on 16 6.7 powerstroke. Or any info that we might can talk about. No codes truck came to us with 80,000 miles and sticking vanes. Customer stated he had ford replace turbo at 40,000 miles in Florida. Also sticking vanes. Would love to talk just a min if u could. Great video by the way thank u

@diesel talk with tony How often do you suggest having the fuel injectors removed and serviced or replaced?

Excellent information, thank you very much for sharing with us. How do I get access to your courses?

I have a 2024 L5P, it has a single fuel filter.

Keep it up! I'm a new tech in the light duty diesel industry. My boss has hired you to come talk with us soon and I have been watching your videos since I learned about them. I'm learning a lot and excited to keep learning more. I want to be an effective and efficient tech and knowledge is the best way I can do that. I've been turning wrenches for what feels like my whole 29 years but turning wrenches doesn't make a technician! So again keep it up! And thank you for passing knowledge onto others!

Tony! Unbelievable videos! We have been dealing with 2019 l5p with no dtc's Cold start is almost a giving a cylinder miss feeling. No codes. And after 7-8 mins of running the idle smooths out. No miss fire count at all. Any thoughts?

thanks tony!

Getting a p2539 code via ez lynk replaced lower lift pump and still having same issue. Truck loses power in between 1&2 shift and in between 3&4 shift under heavy load…

Learned something new today
