You always have the best videos. Thank you

[@robertotoledo1910]

It is interesting how everything must be analyzed and taken into consideration and obviously you start by the closest and the more obvious of what could be and then you move onto the other areas, totally agree with you Francisco thank you, 👋✌️

[@SLUMP317]

Process of elimination

[@JoseMartinez-jl1mk]

Check the water fuel separation filter first, then fuel filter , then high pressure fuel pump, finally check the injector

[@geoepi321975]

Or check all involved parts 😢

[@dmitryxxx26]

Fuel quantity valve too

[@rudydaberry122]

How to check high pressure pump?

[@Akmal-987]

Hello. I have a code SPN 157 FMI 16 Truck not starting and running. Who knows what’s wrong? Any comments please! Thanks

[@user-se6vu8wf6h]

Hey Francisco. Love all the information. Have a question. The the shut off return valve under the cab. Can you please tell me what’s the position to make sure that they’re opened? Right now they both are straight up. And I am not sure if they’re open. . Please advise me when you can . Thanks

[@CanhNguyen-xw4qv]

[@andrewrussell3679]

I have that low pressure problem too and the guy was saying that the fuel rail sensor needed to be changed and that would cost $600 is this true?

[@JoseMartinez-jl1mk]

Gracias

[@freddiefelder718]

I have issues right now, I replaced all of the parts you’ve name except the injectors because they said they aren’t bad. I still can’t figure it out

[@danielduran7867]

Señor Amaya podría darme una referencia sobre los motores Cummins isx12 o X12 si realmente son buenos o muy problemáticos si realmente o son fiables , por favor espero su respuesta, gracias👍😊

[@OmarOporta-gp2do]

Buenas tardes Francisco le saludo desde Nicaragua ese refrigerante que se escapa ai asia donde se escapa Llo tengo un problema con esto consumó de coolan

[@timothymcclure239]

With the recirculation properties of the dd fuel pump, a cracked injector can and will create air in the system. Exhaust and compression games will push through the injector and create a low pressure issue. The fuel pump is not designed to pressurize air. I have pictures of a cracked injector that was causing this and multiple other issues. I don't have a share option on this forum to show the injector.

[@mariodominguez4324]

Como compruebo si los inyectores están bien?

[@armandocandelaria8461]

Hola maya tengo un problemas igual DD15 cascadia 2012 y me da ese code low pressure y acabo de cambiar los filtros de fuel y sigue con los mismos problemas

[@truckmoney484]

I have a 2015 Freightliner Cascadia that won't prime after I changed the fuel pump any ideas??

[@alexcardo6928]

Hey guys I have Cascadia 2017 with 815k miles there’s code came on SPN 5357 FMI 18 and after diagnostic we changed intake manifold sensor and EGR delta p sensor and reset the code, but after couple miles the code came on again. Please advise if you can

[@williamruales1325]

[@phillippianriley2885]

spn 157 fmi 18 . Is that a quanity control valve or hp fuel pump?

[@JarmaineAyala]

Hello i change all my filters, and now is giving me a SPN 157 code, i need help asap please

[@user-se6vu8wf6h]

Francisco, I had put 17k miles on water fuel filter and still not showing no levels . Notice sometimes that when backing up . Truck may smoke like if it wants to stalled out. Think the fuel system is getting air in the lines

[@raulduran9204]

Después de hacer cambio de aceite ya no tengo buena presión de disel

[@obedlockhart9912]

What code is spn004257 it saying something about the injectors

[@abdirahman2044]

I have this issue now where can I get this mechanic

[@basazinabagadu9199]

How much is that cost me fix it fuil injectors ?

[@LonnyHutto-zi9gj]

Question on fuel pressure. Whenever you shutoff the engine, fuel pressure should stay. Had it on the computer and noticed the pressure was bleeding off a lot faster than normal. How do you determine if it is a PLV or the high pressure pump? From looking at all fuel connections haven't notice any kind of leaks. Any help is appreciated.

[@franciscoamayaYT]

you can plug the return lines or injector to determine what is the problem

[@mre4624]

I have SPN 520268 FMI 10 on a 2015 frieghtliner cascadia. It says fuel system problem detected with check engine light on... When I am in motion I hear whistling sound/beeping sound from the engine. Also if I turn off the engine for a few minutes, it will take a long crank before it can start up. When I park overnight, I have to manually pressurize the system to crank. Also have tiny bubbles in the water separator. Please any help with this issue is appreciated

[@stephenkariuki8720]

Replace injectors

[@eleazarbejarano4466]

What code would be SPN 605 FMI 5

[@bigmattus]

Dealer says my pump is out and showed me metal shavings, I want them to change injectors too but they said they’re fine

[@cristianeduardozometarivas5452]

Quisiera que estuviera en español, tengo ese código :(

[@user-uo3tc8yv3s]

I got SPN 157 fmi 17 what causes that?

[@BpMarcus2]

Any update of what it was mines is saying it now.

[@traviscole7069]

I have the same code and whistling as well. Did you find any answers or did you go to a mechanic?

[@mre4624]

I went to the mechanic today, and he said he suspects an air leak somewhere since the whistling gets louder when I accelerate. And also he suspects I have one or two bad check valves for the long crank because fuel is draining back into the tank. But he'll diagnose more.... Will give an update by saturday

[@traviscole7069]

@@mre4624 thanks for the information. I hope it's something simple and doesn't cost too much. Well I called my mechanic and he said just change the water separator filter and see if it gets better when get on the road again, When I replaced it, it was clogged up with dirt. But the code doesn't stay long keeps on and off.

[@mre4624]

That was the initial quick fix I did. Changed all filters, which appeared to be clogged, also had my fuel lines flushed but apparently that didn't fix the issue.. mechanic said he'll check my pulleys, all fuel lines, check valves, and turbo before he starts working his way back to my fuel pump and fuel filter housing... Fingers crossed 🤞.. I hope yours isn't as bad as mine

[@traviscole7069]

Hi, I've went to the mechanic yesterday and he unfortunately couldn't find anything or hear anything. As soon as I got home it started making the noise again. I sent him the video and he said it might be the quantity control valve . I'm afraid I have bad injectors. Watch this guy on KZbin, my truck makes same noise and it was one of the injectors bad. Any updates on your truck, I hope it was an easy fix on your truck. kzbin.info/www/bejne/sH_Wd2tofcqXgpI
