this is a major common problem on a zd30 diesel engine and in many other diesel engines.the bolt shown on the video controls the amounts of fuel return .
Ay I tell you this video helped me I took the bolt out and cleaned when I fitted the bolt back it started with a slight turn of the key. Thanks great work
Thank you so much. This video was so informative. I hve a Zd30 nissanaravan and it was behaving the same. I changed that same bolt and everything is bek to normal now. I used to have a hard time starting it but now haaa all is in good order now. Thank you so much
am having the same problem a new engene with new diesel pump but mechanic say i need to take that diesel pump for receondition can you please advice, the move an later shut down
One info if your car start hard over night: That bosch overflow valve it have a blender for air bubbles bulit in, (that small hol) and it won't keep the pressure into the fuel pump (the fuel pump don't need pressure to work, the fuel pump need fuel inside to work, not AIR . Don't confuse the fuel pump with the injection pump. The fuel pump it's inside the injection pump in this Bosch vp 44. The retun hose are conected directly to the fuel pump by that overflow valve. So if you have any leaking on the return hoses , that leaking will fill with air your fuel pump , throug that small hole (the blender). Check any leakage by filling the return hoses with compress air. (And of course check the one way valve on the fuel filter olso with compres air ). You can check all the injections likege at once assuming that the one way valve is working properly: take out the fuel hose from your fuel tank , (turn and return) fill with compressed air the turn hose , and block the return hose. If you have broken hose you should heare or see it. (The metal pipes can't be checked this way because of the pressure valve from injection) . Again don't confuse the fuel pump with injection pump.
i think you also know the engine runs perfect evwn with the fuel return hose is disconnected, right? meanin even uf there is a leak on the return hose it would'nt hinder the operation of the pump to make the engine run fine
@@endurofan9854 try to disconnect the return hose and after 24 hours idle start the engine . It will start very hard because, your fuel pulp will be empty at this specific pump "vp44". Any engine will run with the return hose disconnected, and in some cases the return hose goes through the fuel pump, and in this specific case "vp44" if you have a leak on return, your car will start hard after 24 hours idle.
In a familiar's nissan frontier, the engine try to shut off only in minimum rpm, in high rpm don't fail, this advice that you share can produce the fail
Hello I have a zd30 and if ever it runs out of diesel or if a supply pipe is removed an put back it will start and the cut off and the pump actually stops supplying diesel to the injectors what could be the cause it will eventually start after some time then will be okay after that
My d22 is doing the exact same thing, air leaking in and out or this 'Banjo' bolt but I cannot find a replacement part!? Anyone know what the actual name of the part is?
Lo..I wouldn’t have shown the trying to start part, if you wanted to replace a bolt. That had nothing to do with anything about car not cranking. I thought you were going to check wire from battery to starter motor.
and there is two washers not one,put one on valve bolt push into holder then put one on inside of bolt as well tighten up,or it will still leak. good effort but not quite accurate.
As for as im aware the only failure point on a banjo bolt can be fit up, as in the mating surfaces. If there not clean or you've dropped it its probably scratched. That's also why NEW crush washes are essential. I'd say you'll still have problems with it tomorrow when it leaks down overnight. The problems more than likely in the delivery lines
Stop being deceitful to pple, if its that buncho bolt how does it affect the car by not cranking. From the first that car shuld have cranked bt wont start, how does a bolt stop the starter from cranking.. wen yo video started yu said the car wont start, did t affect cranking. That bolt has no impact on zd30 injector pump.
im thinking it was just air in the system, not neccesserily throiugh the banjo bolt, i have a similar problem and intending to fix it will come with the results.
Very Fake 1st - You did not run the key to crank the engine, just went to key on not starting. 2nd - The Bolt you removed is the same one you Boltted again. ( the one you show as old is newer than the one you removed. 3rd - The bolt holes are supposed to admit the air yes cause are the same holes that feed the diesel to the injection pump.
Ay I tell you this video helped me I took the bolt out and cleaned when I fitted the bolt back it started with a slight turn of the key. Thanks great work
Well done brother in law. Good observation and technical work
Outstanding video.....its amazing how changing the confabulator, a really simple job, is something that most mechanics just wont consider!!!
Where can I this specific bolt
Great work brother keep it up I will be supporting you 👍 💪 👏

hi where did you find the new bolt,part number any information would be most helpful,thankyou.

Good advice .Well done
Hello from Türkiye . you are a true master thank you
Thank you for the great teach.
Great work sir
Wonderful tip. Will utilize that knowledge. Bravo
Nice tip mate 👍🏻
Great work!
Thanks Good teacher
You can also blank the fuel pressure relief valve.
Thanks for that information. I will try that on my zd30 which is not starting.
Did it work?
Thank you bro
In a familiar's nissan frontier, the engine try to shut off only in minimum rpm, in high rpm don't fail, this advice that you share can produce the fail
yes, low rpm brings in hard start but this was fine with the rpm

Hi, how does one fix the bolt i see theres a ballbearing inside. Mine does not want to start
Good!
My d22 is doing the exact same thing, air leaking in and out or this 'Banjo' bolt but I cannot find a replacement part!? Anyone know what the actual name of the part is?
Fuel needs lubrication.the timing piston is stock up.add 2t oil lubricate in fuel.in loww rpm engine shut off.
thanks, i know low rpm contributes but this was ok.
Well done, but i have tried to change that bolt and when am cranking it, it just showes that it has the air in side the pump
Check the speed at which the engine is
Running when starting or igniting too
What is the part nb for this bolt?
good
Ese racor tiene una valvula que presuriza el petroleo que ingresa en la bomba, si esta defectuoso es dificil el arranque en primer intento.
Which valve is this?
Mi camioneta no aselera le cambie esa pza y sigue igual sigue pasamdo disel al retroceso
Bonjour merci beaucoup de se que vous fête pour nous par contre je voulais savoir c'est le quelle de l'arrivée et la sortie merci
What’s the part number please
What are the bolts called
Wat if is not making key ignition on
Hi mate, so when we suck or blow through The Banjo bolt, the air should pass through? Or it shouldnt?
Thanks
Shouldn't be easily, it's controlled during fuel compression
It will pass through the one small hole closest to the thread. Block that with one finger and it should not pass any air.
Good machanic, my car would be running but once i decide to reduce speed and may be turning it slows to pick. What could be the problem sir.

I had to pump the fuel filter every morning to what he fixed is exactly what the problem was unfortunately 4 u
What is the name of the bolt you replaced that my current problem ...please assist
Banjo Bolt.
Ho did it go? Did you change the bolt?
and there is two washers not one,put one on valve bolt push into holder then put one on inside of bolt as well tighten up,or it will still leak. good effort but not quite accurate.
What is the name of that part?
Banjo Bolt.
bolt part number please
My zd30 have an idle problem the idle is low should i replace the same thing?
No
If it idles
Ok so how does a Banjo bolt fail.
As for as im aware the only failure point on a banjo bolt can be fit up, as in the mating surfaces.
If there not clean or you've dropped it its probably scratched.
That's also why NEW crush washes are essential.
I'd say you'll still have problems with it tomorrow when it leaks down overnight.
The problems more than likely in the delivery lines
there a little valve in there, a blast bearing and spring. If it doesn't close, I think it can't build pressure in the pump.
My ZD 30 is not starting it's only cranking and may switch engine off while driving please help
Check temperature whether the engine heats
That is if your fuel filters are ok, well serviced and wiring ok
Otherwise the best is if I was near to asses that or diognise
I think the banjo bolt is not the issue
It's not
thanks , but it was because the rpm was fine
@@robertepanu get real dude....................
فين ألاقي نفس ذا المسمار
What is the part name specifically?
Hey mate have you had any luck with what the part name is?
Bango bolt
@@up2dskyReturn line banjo bolt.

He's already fixed it. Its just a mock fix....just recreating what he did.

Haya this con artist are awake
You are a beautiful black man
Very Fake
1st - You did not run the key to crank the engine, just went to key on not starting.
2nd - The Bolt you removed is the same one you Boltted again. ( the one you show as old is newer than the one you removed.
3rd - The bolt holes are supposed to admit the air yes cause are the same holes that feed the diesel to the injection pump.
I think he is right. He just recreating the fix he had already done. He didn't fix it in the video. He's just going thru what worked.
You replaced a banjo bolt with old sealing washers, come on bro, what kind of mechanic does that?? FAIL BIG TIME
hello bro, thanks the comment but i was no leakage
Was the sealing washer leaking..If no leaks and not grained don't replace an OEM washer..coz an after market one might not be up to standard gauged
