....Whiteish smoke out of the exhaust, not much, just some and is quite eyes burning. @rumcajs you may remember Avia car and its white smoke - smells and looks exactly the same .....

Yeah I remember those buckets of shyte very well, that smoke was unburnt fuel especially during cold start up, common problem if the preheater wasn't working properly. Also being atmo engines with the inline injection pumps 60's style built under license from French Saviem, there was a little concern about emissions in those days....

Unfortunately what I know about VP44 (6 cylinder light truck version) and its white smoke, that is usually terminal. Since the sole DTC is of a little help what you actually need is the proper Bosch scanning tool which connects to the pump directly to querry pump ECU. Local Bosch injection specialist should have one I'm sure.

I hope I'm not correct...(fingers crossed) now if this is the case where the built in lift pump inside the injection pump is not working (it is simple vane type) properly (cavitating for example) then the issue will be escalating quickly because the fuel is also used to lubricate, control and cool the pump. This is why these pumps suffer failures so quickly when fuel supply is affected.

Lets hope the smoke is there because of lack of injection advance due to less fuel supply and not the starvation taking the pump out.....

I would try (easy for me to say as I got 80 L a minute 12 V electrical transfer pump I use to pump fuel out of the jerries to the fuel tank) direct connection from the container to the IP and see if the same fuel delivery symptoms are happening just to be sure or to discount the filter head but honestly the sooner you get rid of that Nissan OEM filter the better.

If you could lay your hands on perhaps some trucks filter housings (Tatra 148 had a nice one if I remember correctly with primer built in...) Even that Isuzu filter housing you've linked should be fine. Its a pity you are located so far away from Bratislava otherwise I'd get in touch with some of my mates to help you out.

Agree, I think it is time now for that, had mine done a few years ago when I thought I had an issue, for me it was good news (then), I hope it can be the same for Miron.

I'll replace the primer. I don't have a pump that will supply fuel to the IP so skipping the filter assy would be quite difficult. If the new primer won't help, then it is time for pulling some codes from the IPs ecu. Researched it and it can be done with a k-line cable like this one: VAG OBDII USB KKL COM 409.1 Interface VAG409 CH340 Chip for VW Audi Skoda Seat Sale - Banggood.com. Images and software in attachment, I'll give that a try. To unzip the software, you need to remove the .zip extension of the files. I had to split them to 90kB before posting, sorry for that.

Info from other forum:

You can use your VAUX-COM to communicate with the PSG5 pump. You have to make the wiring for yourself, since the communication pin is not connected to the wiring loom of the car.

The PSG5 pump has a 9 pins connector, and pin #9 is the K-Line.

So, you have to make an auxilary cable, with a simple 16 pin OBD connector, and you have to connect the pin #7 of the OBD connector, with the pin #9 of the PSG5 connector.

What we used to do, is to drill a hole on the plastic connector of the psg pump, and connect a wire to the pin #9 of the PSG pump.

Then, you can query the list of fault codes stored in the PSG5 pump.

But please note the following:

You cannot see any measuring blocks information, not even with the KTS software.

All you got is fault codes. By the way, here is the list, not too much.

00080 Fuel quantity solenoid valve, output stage error
00081 Fuel quantity solenoid valve, fault
00082 Angle sensor/IWZ system, fault
00083 Angle sensor/IWZ system, fault
00084 Control unit temp sensor, maximum exceeded
00085 Control unit temp sensor, not in range
00086 Battery voltage, not in range
00087 Timing device control, permanent control deviation
00088 Fuel-quantity solenoid valve, error
00089 Injection begin, error
00090 Speed signal, error
00091 Speed signal, error
00092 CAN-BUS, error
00093 CAN-BUS, error
00094 Selftest, error

And if you surely know, that the PSG pump is faulty, what are you going to do? You cannot repair that by yourself, because for repairing these, you need an EPS-815, or similar BOSCH special equipment.

Most of the time, the IWZ angle sensor, or the PSG control unit is, what causes the fault. Or there is some mechanical damage to the pump.

What I recommend you, is to send the PSG pump to a reliable diesel service center, where they can test the unit with the EPS-815.

Let's see, what they say. If they are telling you, that the pump is OK, then you have to find the problem in the car.

Mate, I recently had air leak issues as well. This was after a fuel filter change.

It seems that my fuel system was borderline in a couple of places. As I disturbed the system during the fuel filter change, i was unable to get thing to seal up again. As I was chasing leaks, I disturbed other areas which caused a couple more issues.

Patrol went in for service running fine.
Came out running like a dog with....
1- Metal fitting from the IP return fuel line was loose and then subsequently rattled completely out. Tightened it.
2 - Some pitting corrosion where the fuel filter mates with the housing. (I think this seal is ok but will change the housing soon, maybe to an after market filter assembly)
3 - Tiny o ring in the water drain tap (bottom of filter) leaking. (replaced it)
4 - Nissan hose clamps have compressed groves in the fuel hoses so they no longer tighten completely. (Replaced with other hose clamps).
5 - There is still a tiny air leak before the filter somewhere.
(looking through clear hose there is a 0.5mm bubble every 2 seconds). Maybe this is ok or I need to track it down.
But she now runs fine again. I hope I haven't damage the IP though.

I am not sure it is relevant to your issue but may help.

After reading a lot of info on here and else where I think I will fit a lift pump (and also change out the fuel lines while at it).

 

[mk96]

I've ran clear hoses and I can see no leaks before filter, just a big air pocket after some time after the filter. I checked the things you mention and all seems well in the engine bay. I need to replace the cracked hoses, but none of them are cracked so the air can enter the system. Waiting for a quote for a new primer from the dealer right now ...

and the quote is $400 pump, holder, filter, ... ok, this will be one of the more expensive choices.

 

[starc]

ask him if he'll give you a discount for two. I need one......

 

[mk96]

I'd buy one maybe from the links I posted above - Diesel Central AU. I am waiting for the response from Italy - Star Diesel.

I think that mob is just the "middleman", they get the stuff from Chinese warehouse for peanuts, you can probably get it yourself directly via Ebay.

That stuff about making your own scanner is a good stuff indeed.

Good luck

[mk96]

Yes, it seems he's a man in the middle, the Chinese warehouse quotes $30, not sure how long the pump will last, but for proceeding further with the diagnosis its fine.

The program I found seems to be capable of reading errors from ECU. Just needs a K-line cable.

Here ==>
Scan K-Line FOR Auto SEAT Volkswagen OBD2 OBDII USB KKL VAGCOM 409.1 Cable | eBay Free shipping to Slovakia for $6.51.

If you are going to make your own then document everything, I'm kind of unsure how is that done because according to the infor you've posted earlier you just need 1 pin to comunicate with the pump so if I understand correctly as long as you have USB to serial interface wired correctly thats all you really need. I use at work similar device to connect to coach/bus ESC controller and it has only 4 cables coming out of the box power +, power - and K-line wire and L-line, the other side has RS232 cable plug/wire to connect to a PC. If I remember correctly see the picture attached.



Full OBDII plug is not really required in this case just correctly wired interface USB/serial is my understanding something like this ==>

FT232 USB Cable USB to TTL Serial Cable Adapter FTDI Chipset Computer Cable | eBay

Unless the datalink connection is required as well so extra 2 wires connected as well for CAN H and CAN L. Here is a pinout OBD2 to K-line

OBD2 to RS232 scheme

I have similar cable or might be exactly the same on the way for the same price. Yes, it seems you need only the pin #9 from the VP44 ECM and pos/neg to power up the ecm to read the data with the attached program. Wanted to use the ecutalk cable because of the included FTDI but it is missing the pin 7 I think, so I need to swap the pins in the connector. Might be an option though.

 

[hz_350]

any of you guys in europe looking for a primer get on www.partsouq.com put in your vin and find the part i looked last night a complete primer setup was around $200 us or just the primer itself about $100

Indeed that's what I was thinking earlier as I have that cable too. However there are only 6 wires there and it appears that one still needs some kind of interface to K-line aka ELM327 as FTDI USB interface itself is just a simple serial converter. I'm not really sure unless the wire in question is the TXD yellow as the green wire which is cut on mine is RTS. Something tells me that ECUtalk cable isn't compatible. Perhaps it would be if it plugged to another controller/interface which has K-line support.

I'd probably just hack full spec OBD2 to USB cable.

or I actually found an DIY scheme ==> USB K-line adapter scheme

Thanks for that, couldn't find that by myself. Merchant in UAE

Ordered the primer from UAE, for $100 US it's not that bad and will be delivered by fedex in 3-5 days. The stuff from China warehouse might take up to 60 days to arrive and I still save some cash for a pump rebuild if needed.

That is why I ordered the VAG KKL cable, which supports K-line.

Yeah, but you still need to make an adapter wiring piece like Y to make it from that OBD2 plug pin 7 to VP44 plug interface pin 9 as well as include the 12V+ and ground to power up the pump ECU. All this Efing around because both the Bosch and Nissan just couldn't work together and of course Nissan and its idiotic proprietary Consult protocol despite having OBD available for years.Then to confuse everyone Nissan would fit fake OBD plug with Consult wiring only!

Typical automotive car makers and their greed.

I might do the same as I'm really curious about communicating with the pump ECU directly.

Regards

 

[mk96]

Isn't the Y piece needed just for the Bosch KTS? I think we need to connect the pin #7 OBD and pin #9 VP44, the power is supplied from the battery itself or can be. I'll search for more info.
Source: Bosch VP44 PSG Control Unit Diagnostics - OBD2 Diagnostics Wiki
and: Bosch VP30 VP44 injection pump repair solution

And the OBD pins of the VAG KKL would be populated like this:
12V + = 16
GND = 4+5
K Line = 7 (pin #9 from VP44)

With attached software you should be able to read/erase the DTC codes. I tried to run the program and it runs under Windows 7 and asks for a COM port, but refuses to start under Windows 10.

VAG KKL interface has to be powered from external source so B+ and ground needs to wired in as well to the Y line so as a minimum 3 wires out to the IP and from battery pos and neg.

I got that software working in GNU/Linux under Wine emulator but not being connected to anything I'm not sure how I'd fare any further. I know I can always run virtual machine where I have Win 7 (thats how I run ECU Talk software). In order to run that software in Win 10 it probably has to run under some compability scheme inbuilt with the OS.

Tried compatibility under W10, but won't help. It is an application from 2007. It should run under Linux as long as it has access to the needed COM port.

EDIT: Runs under W10, just my notebook doesn't have COM port. I created virtual one and runs fine

EDIT2: Pump can consume up to 8A, use adequate wire gauge.

To get older programs to run on windows 8 I had to disable "driver signature verification". Probably the same for windows 10.
