common cause of ZD30 , diesel engines failing to start idling

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 .

[@percyhomodza120]

Well done brother in law. Good observation and technical work

[@zakariyajeena8937]

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

[@riamriam6758]

Very good video here brother. Thank you.

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

[@gavincrispin1436]

Excelente video 👍, gracias por compartir

[@ianpope7061]

Outstanding video.....its amazing how changing the confabulator, a really simple job, is something that most mechanics just wont consider!!!

[@jakecharles2123]

Where can I this specific bolt

[@mehmetfatih1988]

Hello from Türkiye . you are a true master thank you

[@clivechangwe1788]

Wonderful tip. Will utilize that knowledge. Bravo

[@MsDonGoofy]

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.

[@endurofan9854]

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

[@MsDonGoofy]

@@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.

[@philbertnestorytuna9833]

Thanks Good teacher

[@WelcomeToDieBaby]

Thank you bro

[@kevzoblefiaz2072]

Thanks for that information. I will try that on my zd30 which is not starting.

[@JaredKnopper]

Did it work?

[@mfp4136]

You can also blank the fuel pressure relief valve.

[@ctxgpsylince9308]

Hi Robert, Thanks for this, you're a legend. Do you where the cam shaft sensor is on that engine?

[@sanjorge86]

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

[@robertepanu225]

yes, low rpm brings in hard start but this was fine with the rpm

[@delwynkeyser4294]

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

[@jermainequinn2731]

Hi, how does one fix the bolt i see theres a ballbearing inside. Mine does not want to start

[@wildnature0.0]

Good!

[@GeorgeBwalya-fl3gr]

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.

[@alvinpaul1689]

What is the part nb for this bolt?

[@cesarjorgemurillobarientos1813]

good

[@stapesg]

What’s the part number please

[@larsdoityourself3483]

Fuel needs lubrication.the timing piston is stock up.add 2t oil lubricate in fuel.in loww rpm engine shut off.

[@robertepanu225]

thanks, i know low rpm contributes but this was ok.

[@SolomonMwapenyaSollobuilders]

My car is cutting fuel when I'm driving especially when I'm slowing down or up hill. Even sometimes in 3rd gear

[@xDSTLx]

What are the bolts called

[@thomaslagreca9428]

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?

[@ELIASNGOMA-lc2qf]

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

[@robertepanu225]

Check the speed at which the engine is Running when starting or igniting too

[@GurwinderSingh-xk5fb]

Hi mate, so when we suck or blow through The Banjo bolt, the air should pass through? Or it shouldnt? Thanks

[@robertepanu225]

Shouldn't be easily, it's controlled during fuel compression

[@rocknral]

It will pass through the one small hole closest to the thread. Block that with one finger and it should not pass any air.

[@cesarsanchez5880]

Ese racor tiene una valvula que presuriza el petroleo que ingresa en la bomba, si esta defectuoso es dificil el arranque en primer intento.

[@Fredy44]

Which valve is this?

[@PetronelaGurumombe-zj5cx]

Wat if is not making key ignition on

[@fatahben8718]

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

[@KelvinNjolomole-ie8go]

You said they're three main causes but you never mention the last 2 tell us sir

[@kennedy5148]

What is the name of that part?

[@tomhenz]

Banjo Bolt.

[@mcdonaldchilepa6934]

What is the name of the bolt you replaced that my current problem ...please assist

[@tomhenz]

Banjo Bolt.

[@rocknral]

Ho did it go? Did you change the bolt?

[@betoordonez5694]

Mi camioneta no aselera le cambie esa pza y sigue igual sigue pasamdo disel al retroceso

[@2cezand]

bolt part number please

[@gavincrispin1436]

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.

[@muhamadbinlias4080]

I think the banjo bolt is not the issue

[@kevmitch4992]

It's not

[@robertepanu225]

thanks , but it was because the rpm was fine

[@cgis123]

@@robertepanu225 get real dude....................

[@Batsahead]

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.

[@siyamthandamsomi7421]

I had to pump the fuel filter every morning to what he fixed is exactly what the problem was unfortunately 4 u

[@sproket168]

Ok so how does a Banjo bolt fail.

[@sproket168]

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

[@rocknral]

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.

[@allendelacruz5822]

My zd30 have an idle problem the idle is low should i replace the same thing?

[@robertepanu225]

No

[@robertepanu225]

If it idles

[@tendaigumbo1103]

My ZD 30 is not starting it's only cranking and may switch engine off while driving please help

[@robertepanu225]

Check temperature whether the engine heats

[@robertepanu225]

That is if your fuel filters are ok, well serviced and wiring ok

[@robertepanu225]

Otherwise the best is if I was near to asses that or diognise

Hey mate have you had any luck with what the part name is?

[@up2dsky]

Bango bolt

[@rocknral]

​@@up2dskyReturn line banjo bolt.

[@kudakwashenkonzo6255]

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.

[@robertepanu225]

thanks but it was after changing because the rpm was fine

[@charleserenesto2452]

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.

[@moderndewah5443]

If the car wasnt starting how come the temperature gauge is almost midway? Who is fooling whom here

[@rocknral]

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

[@acaciobango4240]

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.

[@rocknral]

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.

[@duanedonaldson2262]

You replaced a banjo bolt with old sealing washers, come on bro, what kind of mechanic does that?? FAIL BIG TIME

[@robertepanu225]

hello bro, thanks the comment but i was no leakage

[@josephinebiruri3866]

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
