@@rob3865 there is a little hole in the nut that you need to align with an arrow on the car body ( if Im correct).On 1:28 I just marked with a marker and thats it, not paying attention to any manufacturer marks ;)
Hello, I don't remember for sure, but it takes something like from 1 to 2 minutes may be 3 but with pauses. It's like you crank it up for 30sec if it doesn't start, just apply power to the electric fuel pump again, and it will start. There are no complaints from the owner of this car about starting any way, so dont worry. And onother way you can fill the system using hand pump (but with 100% clean fuel ) thru the injector high pressure pipe. Just connect hand pump hose to the one of the injectors HP pipe, slacken union nuts on the other 3 injectors and pump in fuel until only fuel come out without air bubbles then tight everything back plug in connectors and l think engine will start very quick. I will show this pfocedure in next video (not long ago I do this on passat b7 2.0tdi and engine starts right away) But remeber fuel must be 100% clean.
Thanks for this great tutorial. My question is with the injectors. I understand that I first open the fuel pressure nut of the first injector while the other three nuts are closed. I activate the fuel pump with 12v for a few seconds and close this first nut. Then, I loosen the nut on the next injector and start the pump again. I repeat this procedure until all 4 injectors are complete. So, only one nut is loose at any given time. Is that correct?
i had a failed hpfp and i wiped down the tank with a rag and that the car is on 261000 miles im replacing injectors an hpfp and filter but have oil dilution from the diesel can this Couse it too
Hi! BMW E90 318d, N47 engine code, 2008. The car stopped accelerating, then I turned it off and it wouldn’t start again, or only with great difficulty. When it did start, it was shaking, as if not all cylinders were firing, and afterward, it wouldn’t start at all. After removing the fuel pressure regulator valve, we found metal shavings. The mechanic checked it, but it wouldn’t start, and he measured that the pressure sometimes drops. What do you think could be the issue? What should be replaced? The fuel pump works, and fuel reaches the return lines. Any advice would be greatly appreciated.”
Hello.Well i think the main issue is that the metal shavings from high pressure pump went straight in to the injectors and maybe all of them are now dead. So all you need to do is basicly in this two videos, part one removing instaling hipressurepump and part two cleaning fuel tank and starting. Now You need to 1 remove High pressure pump and replace it, 2 check injectors on the test bench(maybe some of the are working) if not replace them, 3 clean fuel rail and sensors on it 4 chek electric fuel pump in the fuel tank is it working good. 5 clean all fuel lines and fuel tank from metal shavings. 6.bleed fuel system, start the engine and have a nice day. 7 you can add some addativ in to the fuel that lubricate fuel system components to prevent this ''beautiful'' high pressure pump boschCP4 crack again or never drive with low fuel level (because air and this fuel system don't go together well)
Hi, I have replaced the HPFP on an e92 with the N47 engine. I carefully followed the steps. When I was trying to bleed the system, I found that there was no fuel coming out of the HPFP. I tried bleeding with scan tools and also with an external battery plugged into the low fuel pump (still nothing coming out). I cranked the engine a few times to see if the rail pressure would come up, but it did not. It shows 0bar. I know the low fuel pump is sending fuel, I have checked all connections (no leaks), clamped the return lines to build up pressure, checked for DTCs on the DDE. I have also reinstalled the old one (which was working ok ish before replacement) and still found the same problem, nothing coming out of HPFP. Do you have any idea what I can do? Thank you
@@HintSlice No, I haven't found the problem yet. I run out of ideas since I know intake pump is correct (pressure 3.8 bar), i put a different regulator on, new fuel filter, changed both sensors at the rail, system has no leaks. I tried to bleed the system and still not fuel coming out from the hpfp. I put two different hpfp and i am having the same problem with both. I just don't know what else to do.
So electric pump in fuel tank is working fine right? And if you remove fuel supply line from HPFP fuel will flow and when put back in place it doesn't is this right?
@@AJ_RamRacing Did you solve your problem? I dont quite understand how you could read 3,8 bar from the lift pump if you dont get fuel past the hpfp, since the regulator sits in the rail? Anyway, did you check if you installed the fuel filter in the wrong direction? Or maybe mixed up the fuel feed and fuel return lines...?
you can cut open the fuel filter with scissors and see if there are any metal shavings or by removing fuel pressure regulator on the high pressure pump
@@blackace4423 well then step two remove fuel pressure regulator on the high pressure pump. And what is the problem with your engine? I mean what is the condition? Because one wise mechanic is saying : "condition cause correction confirm" Dave's Auto Center.
great job! thanks for sharing. gives me the confidence to diy this job.
i hope you succeed
@@HintSlice is there a specified torque for the pump locking nut?

Man, You are master of practicality!
And you share it! that is even better!
GOD Bless you!
Thank you sir. And GOD BLESS YOU TOO!✌️
hi, how long it did it take if cranking for the engine to start? thanks. you’re videos helped me do my hpfp on my f11

Hi. Yes that is correct
There is another way maybe even simpler is in this video on 11:12 th-cam.com/video/UsAmawGIBBE/w-d-xo.htmlsi=eeDAm_vzAsc30yDn
i had a failed hpfp and i wiped down the tank with a rag and that the car is on 261000 miles im replacing injectors an hpfp and filter but have oil dilution from the diesel can this Couse it too
would all that work fix it
I think yes

What is the easy way to look for metal?
you can cut open the fuel filter with scissors and see if there are any metal shavings
or by removing fuel pressure regulator on the high pressure pump
@@HintSlice Thanks!
Np ;)
@@HintSlice Did this but no metal shavings inside the filter? 😕
