Mitsubishi Pajero Montero Gen 3 2001 3.2 DID Dieselpump problem 

Tank delamination causes the metallic paint in the fuel tank to get into the injector pump and congeal within the electromagnet throttle inside the top of injector pump, this can draw up errors 48 and 25. The only way to solve this is to replace the tank or dip it in an ultrasonic cleaner and remove all delamination. The pump itself will need checking, cleaning completely and possibly replacing the electronic throttle control. You can check for delamination by emptyng your fuel filter into a clear glass and you will see the metallic particles floating inside it.

Sorry I know that my reply is too late but I know very well these sympthoms. I confirm that 90% of the VRZ pump malfunctions are due to the GE failure (Governor Electric). The part mounted on top of the pump. In this video your engine starts quick as usual, I am 100% sure that the mechanical components of your pump still in a good health. So, you have an electrical problem and error code 48 confirms that. Two things are causing the Electric Governor to fail: first the metal filings coming from the fuel tank and this is the main source of almost all the VRZ pump problems (mechanical & electric)!!! These extremely thin metal filings accumulates around the electric coil of the actuator inside the GE (since it creates a magnetic field) and this makes sometimes a short circuit. Second inside the GE there is a fuel temprature sensor that fails and it causes the same symptoms as in this video. Unfortunately, this sensor is not available and is not sold separately but BOSCH provides a full GE assembly which is much much cheaper than buying a whole fuel pump (arround 300 Euro approx.) Please don't discard anymore your VRZ fuel pumps since a simple cleaning and/or an electic component replacement will solve the problem. In your particular case I guarantee that your fuel pump will work again as new just by replacing the GE. I can provide you the part number if you need. On the other hand if you get a fuel pump failure at the mechanical components level you will get only an engine malfunctions problem and you will never get a "check-engine" light ON !! An advice for all Gen 3 owners: I confirm that 99% of the VRZ fuel pump failures are because of the metal filings coming from the fuel reservoir. An internal enamelling that has a tendency to desintegrates (because of a lack of resistance to additives such-as injector cleaners I presume) and will be sucked by the fuel line toward the fuel pump and none of the fuel filters can stops 100% of these metal filings!! So, I highly recommend the replacement of the fuel tank (if you find any metal powder inside your filter) with one from the latest Gen 3 models (2006 MY) or better a Gen 4 reservoir with some modifications at the pipes level. the Gen 3 pipes has a wider section. Just for your reference I replaced the GE of my injection pump and the fuel tank on my 2002 Pajero 3.2DID since 2012 and my fuel pump still performs as new up today. I adviced my freinds to do the same and none of them get a pump failure afterward. Still at your disposal if any repair instructions are needed.

It's over checking

These pumps are total crap.. lots of sensors, electronic shit, and expensive to repair.. I changed mine for the mechanical one from a pajero 2.8 .. all mechanical.. runs perfect..

I also checked the fault codes and the diesel fuel filter, the filter was full of rust and water. Need to change the diesel pump.

You fix it?

Steuerzeiten überprüfen.

sorry to ask, the car is the same as in the video, if the rpm is high idling around 1000 and using AC it becomes 1200, what is the problem? thanks in advance 🙏

sir i start my pajero 3.2l then suddenly the rpm is to high its above 5000 rpm then goes down to 800 rpm.i need some advice sir thank you.

Send me a pm, i build mtdi for em.

same problem with how did you fixed

Bonjour quelle étais le problème ?

Boa noite sou do Brasil e estou tendo o mesmo problema .gostaria se possível que você me passasse qual foi o problema e oque você fés para concertá-lo. ate mas obrigado.

Help pls.! My car Pajero 3 did 3.2, from few days is having the same simtom. If you are kind, pls i would like to know how did you fix this problem. I would realy appriciate your kind answer. Tks.

Maybe EGR it's black smoke but yellow smoke i don't know

I had the same problem but fixed it myself u need to adjust your pump timing

Maybe EGR?

Pmh

Hi Kim Dig, finally how did you fix the problem? I have the same trouble, I change the pump sensors and function for some months, then again I just pull out the sensors they was dirty of oil, clean it and swap them, and runs for some weeks now again the same symptom, I am making some research about this problem, i didn't want to change the pump until I'll be sure that's the last resource. Thanks in advance for your help.

what))

who is SC?
