Hi.. may i ask. I have the same pump on my chev captiva. The fuel comes in from the low pressure pump into the high pressure pump but very very small drips come out of the pump to the common rail. Does this mean something is not ok with the pump? Need a service like this one?
Can you tell me if my fiat bravo 1.9 110kw having cold start, lower power and slow accelerating issues because of this on your video? i repaired all 4 injectors. Thanks so much.
👍 Did you actually replace any other parts other than the regulator or did you just clean and test? I have Borsch 0445010206 I cleaned the injectors in ultrasonic cleaner but didn't take them apart, I didn't touch the pump, now according to G-scan I only have 383.9 Bar instead of 1600 Bar DTC P1186 =Minimum Pressure at Low Speed Too Low. The car won't Rev past 3000 rpm.What did I do wrong or was it bad timing. If I get the pump service how long will it last? Thanks
I changed Inlet metering valve(IMV) because that's the key function part. and using the other components after cleaning. CODE P1186 ; 1. check each injector's return fuel quantity, if return comming out like stream, that's the broken injector. 2. Inlet metering valve malfunction; please change IMV, and please use Bosch or MOBIS genuine, some chinese product on online mall is useless. Most of this kind of cases can solved after these steps. However if it's not solved. check below option A. fuel filter defected B. RPM issue ; air intake system is not airtight
Thank you for responding. I found the problem, injector copper washer not sealing because diameter is smaller than original, part number correct, I will contact the supplier. Thanks again much appreciated
i have a kia ceed crdi and sometimes when i start the engine and try to pull away from a stop it starts bucking back and forth though the rev range but eventually goes away, do you think this is the cause?, it only does it after a warm start up driving from a stop in 1st gear.
Good day I have the same hpfp in a4 3.0 tdi, I have an issue after I chip tuned it, when I push pedal to the metal engine stops to pull and freeses, but car start and rins fine if use more considerably, could it be starvation of fuel due to hpfp is to old I have 300 k of km, thnx
@@nos00The main problem that there no fault codes, I have already replaced fuel pump in the fuel tank and fuel rail with pressure regulator sensor only problem that is displayed is bad closing 6th injectorand now I will address it
In this case, there are a lot of return fuel quantity from injectors, when your car has delaying on crank it might be nozzle of injectors has damaged; can't spray fuel. So you should check the injector fuction, and fuel pump, IMV valve. thanks
The abnormal pressure generation in each piston area was due to carbon buildup. The main issue with this pump is the inlet metering valve, which is the most problematic component. Additionally, the internal carbon buildup can cause irregular pressure formation, and one of the pistons is constantly compressed, leading to weakened piston spring tension, which may prevent proper pressure buildup.
when you cranking check the rail pressure comes up normal and also check retrun leak. if return leak is too much, that's injectors problem. return is normal, you have to check common rail leak or pump malfunction. rail sensor or low pressure pump might been damaged. and IMV malfunction. we need to see in field to know what's worng about this case, but summary of case is this. thanks
@@nos00what about the fuel that comes out of this pump that you are repairing, can this cause a bad cranking? there was a little fuel that got out of that pump, but now is getting bad and there is a lot of fuel that comes out maybe beacause of winter cold temp, but for now car is not starting, its just cranking but not starting, is this the pumps fault? and if yes can u tell me where can i find this pump in europe because is very hard to find this piece, thank you
Hi. I have a BOSCH 0445010404 (renault 167008960R) fuel pump which leaked fuel at cold starts, I purchased a SH pump the same PN, but with this SH pump I have active error "low pressure pump open circuit" from the first ignition, even before starting the engine, and the tank fuel pump is making strange noise. If i put back the original pump that is leaking the error dissapears and the tank fuel pump is silent back. Both high pressure pumps are the same PN (bosch and OEM PN). The engine starts also and has the nominal fuel pressure but the error remains active continuously with the SH pump. Do you have any advice for me?
@@nikzchoi you need to install only the original, it will not have worse quality and service life, what prevents you from buying the original F 00R 0P0 253?
Hello my friend, how many holes are there in my Delphi injector nozzle and what is the hole diameter, I would be glad if you could help me, injector code: embr00203D 33800-2A780
The product with the code 33800-2A780 is not available in South Korea. A similar product, 33800-4A710, has 8 nozzle holes. The diameter is too small to measure

It seems like a pump issue. You might need to overhaul it. Alternatively, it could be an issue with the IMV (Injector Metering Valve).
Hi, what liquid solution you normally use in your ultrasonic machine?
Wich is the torque in N*m used for the 4 bolts at 10:23 sequence?
Well done and professionally achieved.
Thank you!
Are you using the same o-ring's and rubber gaskets or replacing them with new ones?
We check the condition of the O-rings and gaskets. However, not all of this is shown in the video.
hi.boss.this 4a420fuel pump,when we installation at engine we need find the mark or just pull in only?
Can you tell me if my fiat bravo 1.9 110kw having cold start, lower power and slow accelerating issues because of this on your video? i repaired all 4 injectors. Thanks so much.
It seems like a high pressure pump problem.
Hello, I have a question, what grease do you use for seals and pump elements during reassembly?
Diesel :)

Many parts can make the symptom you have, EGR, Intake, CRDI system, Transmission, etc.....
It must be distinguished.

It seems like replacing the inlet metering valve on the high-pressure fuel pump would be a good first step to address the issue.

SH PUMP What do you mean?
Is it a new pump?
@@nos00 no. I bought a used pump but fhe same PN 167008960R. And with this pump I have the issue described above..
Please note.
If there is a problem with the high-pressure pump, try replacing the existing inlet metering valve with a new one.

I don't know what you mean.

Not same as on side of shaft gear, in case of others, There's a gap should headed to pump when you assembly.

Did you leave the old : oil seal, filter, low pressure pump, ?
Do you warn the client that this is not a quality repair?
Thank you
As per my experience, as long as the original seals are soft and functional, it is better than the New replacement seals with low quality rubber..
@@nikzchoi
you need to install only the original, it will not have worse quality and service life, what prevents you from buying the original F 00R 0P0 253?
what is pressure retension
Pressure will not be maintained if there is a leak in the pump.
