Another issue is not use OEM filters. I got filters from Amazon probably from China and I had this issue of not starting. So make sure you put filters from Detroit.
hallo Alrey, we have the problem for engine OM 471 LA, i think the engine similar with detroit DD13, we have a problem ih engine idle condition, the engine is noise and abnormal idle, we have check for rail pressure sensor, over flow and qty solenoid valve at HPP, but engine not yet normal, after we replace HPP with assy component, the engiene can be normal condition, do you have similar problem ? after look your video i think we need to check 2 stage valve like in your video.
Thank you for this great insight! Is it safe to runs the engine longer than 1 minutes with the return line blocked off, without risking to damage more parts? The two stage valve has some side openings, holes, does it have to be specifically screwed in to align the holes with something inside the fuel pump housing?
Thanks for the video. I've got this truck model of 2001 and it cranks but wont start. The mechanic replaced its starter and it didn't help. Now, he says it might be the flywheel but I don't trust him anymore. The question is how do we know if starter is cranking the engine to look for other issues like fuel?
If the engine is turning over/cranking but not starting then it is not the starter or flywheel. If you try to start it and it just clicks or does nothing at all then it is likely a starter or electrical issue. Sounds like you have a fuel, air, compression, or perhaps a timing issue.
Thanks for the response. The issue is how to know if the engine is turning? Is the engine speedometer accurate enough to show the low rpm?@@alreyindustries
I'm having this issue right now. Wouldn't start but I could prime it then start. Now it won't prime at all. I changed the filter housing. Both of those check valves. The ball check at the bottom of the small filter. If I block the return line it will prime. My only other thought is a leak from the emergency shut off valves. Any suggestions?
@@robinsonr6had similar symptoms when I replaced the injector pass thru seals on my DD15. Engine would crank but not start, priming would send fuel back to the tank. Phoned a Detroit Guru who said to remove the connector to the solenoid at the front of the fuel pump. He said this will cause it to go to high pressure on crank. Got my engine started in minutes after trying for 2 days. Not sure if it was air in the system or this valve stuck.
holy fuck this just happened to me 2 hours ago , I didn't figure it out because I don't know much but I changed the fuel filter and tried priming it and it would not build pressure at all , fuel filter splines were not broken or anything and they were installed right , the engine started only with starting fluid but didn't stay on , I did find out it was a check valve but I thought it was located under the big fuel filter lol
I don’t have any videos on those yet. I will keep that in mind though and try to get some out there. From what I have seen they are pretty good and reliable engines. I remember an issue with oil consumption. I think there was an issue with liners or something like that which was causing the engine to burn oil on some models. Other than that I can’t think of any major issues I have seen personally.
I have a 2020 DD16, 40K miles on it and it started to give me this problem. I would have someone turning the key while I prime the pump and it would start right away. Sometimes it would start up normally after cranking for a while.
Having same issue. But valve looks good. How did you block off return ? So we can try that to rule out the valves. Installed new fuel pump and now it loses prime won’t start up. Looks like fuel may be going back to tank when trying to crank up engine.
The brown fuel line coming out of the fuel filter housing, directly under the hand primer is the return line I do believe. We removed that fitting and attached a homemade fitting with a valve on it. We shut the valve during cranking so that the fuel could not return during cranking, then opened it after it started up. Essentially we added another check valve to see if that was the issue and it was.
Was doing an oil change and large fuel filter was stuck on when finally got it out the plastic insert got a little damaged and some fuel filter plastic pieces fell in there. Tried to clean it out as best possible but now truck only starts if I prime it and will run just fine but shut it off and I have to prime it again
@@adrianarce9427 a rule of thumb I try to go by is: “if everything was working before you did something, go back to what you just did.” Those filters are spring loaded at the bottom and there is a little nipple at the bottom of the filter that MUST lock in place at the bottom of the filter housing when you put it in. Maybe check the old filter to see if that broke off the bottom and is stuck in the filter housing. If not, you may need to pull the new filter and double check that you got that nipple inserted into the correct place.
Possibly. But if you have it all apart and can get a new one, I would. I wouldn’t want to go through all the trouble of taking it apart twice if you don’t get all the rubber out or something like that.
I have a 2014 cascadia DD15 . I took it for service ( oil change and fuel filters ) they are having the same issue., loss of fuel pressure, and it won’t start . Does DD13 and DD15 have the same fuel system ? So I can show them this video to try this
I have the same problem where my truck won’t start. However, the freightliner dealership in Lancaster,pa told me I need to change to a 2-filter system. So they don’t sell the two-stage valve anymore! Parts alone is about $1600. Any other way around this? Where can I buy a two-stage valve?? I have a 2011, D13 engine. Please help..

@@alreyindustries thank you, for the fast response, what do youthink about the bubbles in air separator filter? When truck shut off fuel from water separator filter dissappear
@Pablo Lizano could be a stuck open check valve in the base of your separator housing. Or, it could be that the cap on top or the oring at the base of the glass is allowing air in. Check that both of those are tight and not cross threaded. Other than that, I’m not sure.

Thanks for the speedy reply...I have another question for you.... Would a improper electrical ground along with low fuel and multiple attempts to start/crank the motor, could it cause the overflow valve to get stuck?
@@troydeleon1162 that’s a lot of variables. I take it you don’t have fuel pressure. How did the issue begin? Any service or anything performed on truck prior to loss of fuel pressure?
Well it all started with battery issue... I thought my Battery was dead so after multiple attempts of jump starting and not getting anything we realized that the ground strap was broken, I replaced the strap and went ahead and turned the key... The truck started within about 30 seconds of the engine running it revved out a shut off on its own... Tried to start it again had to hard start kept the key down it eventually started this time it revved out and shut off in less than 5 sec... I thought maybe air had gotten in the fuel line due to low fuel in my tank so we primed and that did not work either..
I have dd15 cascadia there is an issue there is no fuel on the water separator if i need to start i have to pump always please any one who knows this problem ? Please advise me. Thanks
@@notkirill6991 maybe pull the fuel filter cap and check to see if they are full of fuel. If not, fill them up first and then try to hand pump it again. I’ve had problems with getting them primed before without a machine. That’s where I would start before pulling anything apart.
@Alrey Industries Top Tech Diesel sorry forgot to mention I put diesel into fuel filter and into water separator. Pumped for hours on end, no luck truck doesn't even stay running with starter fluid. I'm getting code for low pressure in rail. Thank you so much for getting back to me by the way
@@notkirill6991 no problem. And ok good to know. Yea the two stage valve could be the issue.

When you replaced the two stage valve did it come with like a seal or o right that goes into the hole of the valve?

Which troubleshooting were you following
I learned that the hard way
Do you have a part number ? I’ve been trying to find this part online
Any chance you have a fuel flow diagram for the dd15 ,got a 2011 cascadia i gota fill the filter housing pump it jus to start the truck
Was there any engine light or code for injector pressure?

I don’t think either photo references were wrong. The first photo the version 2 pump. Your “correct” photo was for a version 1 pump.
Excellent diag!
Good video. I'm at a shop for what I thought was just a fuel filter. But alas they can't get it to run. Maybe this will work.
What engine model? Let me know what they come up with.
Can't you just use an o ring pick or something to get the plastic piece out of that 2 stage valve?
