O, time for the big guns...got any advice? 2001 Pajero 3.5 GDI 6G74
Liiving in TZ and driving north to Arusha. Filled up at the wrong station (OILCOM) and got a load of bad petrol. Within 40km we were losing power and within 100km we were creeping into Same. The next morning we ran OK for a while but after 50km we lost power again. In Moshi we had the fuel tank dropped, drained it (petrol mixed with parafin) and bled the system best we could. Cleaned the in-tank filter to whatever extent possible.
Next day we took the car to Bosch in Arusha and hooked it to the computer. Got several readings including ignition coils, fuel pump, etc. Replaced fuel pump in tank and it cleared up most of the errors, including the ignition coil errors. One it did not was the fuel pressure sensor.
Returned to Dar and ordered one. It arrived and we had Bosch install it in Arusha. Cleared that error and came up with a new one - fuel pump at engine!
Ordered new fuel pump and it arrived two weeks ago. Bosch replaced it last week, and it ran fine in garage, but once under load during road test it lost power again!
Bosch hooked it up to the computer again and, the new reading is "Unit Control". Monday Dec 13 they are hooking it again to give me more precise reading, but my god, does anyone have a clue what the heck is going on!?
Very soon my 'investment' in this car will be half what I paid for it 6 month ago.
Any clear thinking folks out there with some ideas about what is going on? Who to see here in Dar es Salaam? The Mitsubushi dealer, Diamond Motors, is not helpful at all and have not had any spares that I've needed. What they say they can order is as much as 5x the price on a UK, SA, or AU website for anything.
Hi Brian your engine runs very high compression ratio so the wrong fuel will be very detrimental. Not sure if you aware but to my knowledge your engine has two fuel pumps one in the tank and one on the side of the engine, i also think it might have a small filter infront of each injector ?

Hi thanks for your reply. Yes, we took everything apart and cleaned and scrubbed. We put the in-tank one no the test bench and it came out fine.
Yesterday they put it back on the diagnostic computer and to a reading that the Control Unit is faulty. It appears that it is isolated to the computer now. They are going to call me later and give me the number of the fault code also the part number.
Any idea how to reset the computer or where to get a replacement unit?

Well, I finally got my Pajero back last 5 days ago and while I am grateful I still don't know what happened. I finally met a mechanic here in Dar that works miracles. Thru a friend who had a similar problem (and whose car is working now for two years without a problem), I called him and explained what had been happening. After I finished he said he could take care of it and that I'd have my car back in 24 hours, and not to consider paying him until I was satisfied. I gave him bus fare to Arusha.
Sure enough, he called me after 8 hours in the engine well, and my Pajero was fixed - guaranteed, he said. Furthermore, he said it wasn't my fuel pump, and he took the new one off and replaced the original so I could sell the new one. He said that the issue wasn't the fuel pump or injectors, but fuel starvation in another part of the system that mechanics don't check and don't know how to fix because they are too focused on what the computer tells them, not what listening to and feeling the engine tells them. Essentially, everyone looks at the pump, injectors and whatever else, but not the places he looks, which is why there are so many abandoned Pajeros in garages here. He says he worked for Mits here for many years so he maybe has specific training as well.
He's not really keen on explaining the entire problem to me, or anyone. He left my other mechanic at Bosch in the dark, but that mechanic is impressed and completely stumped. He clearly knows what goes on in these GDI engines and sees it as a way of life and a way of making a living. He left Dar the other day to go to Nairobi to fix two other Pajeros with similar problems, and I referred him to a shop in Arusha where there are several dead Pajeros (all fuel system problems) so he'll spend some time there making some cash and helping out some folks whose cars haven't worked in months.
My Pajero had spent 3 full months in Arusha unable to move.
My guy is available for travel and I'm happy to recommend him!

Hi Brian,
I am from Nairobi and I have a 6G72 GDI Pajero. I have been having an issue in the sense that my fuel consumption has just gone up and I have gotten it cehecked with the diagnosti tool but all is well. Cant get to the base of the problem. Need an expert to have a look at it. Can you please provide me with the contacts of your guy so that I can contact him and get him to check out my car.
Thanks in advance.

Hi, living in Helderberg Area of the Western Cape of South Africa, unfortunately thats a bit for from TZ to make use of your contact. Perhaps someone can advise me??
I have a 99 Pajero IO that was brought in from Japan with just over 100,000kms on the clock. I had just recieved the car and seeing as I didn't know if it had been serviced previously after driving the car for about 2 months I sent it in to a small service garage near my house. The day after the service I noticed it was very low on fuel so I drove to a suspect service station and filled up. About 2kms down the road it started spluttering and stopped. Thereafter it stoped and refused to start again (The engine would turn over but it seemed like the engine was starved of petrol). I got the car towed home and phoned the mechanic who came to look at it the next day. He said that it must be the fuel filter (as far as I know the IO doesn't have a fuel filter in the tank, only a microsieve before the pump) or an electrical problem, that he didn't know what to do and so that it was no longer his problem. I sent it in to the auto electrician who worked on it for just under a week, charged me R700 and told me that it is most probably the relay, seeing as providing the fuel pump at the back with a steady supply of current starts the car without problems. In any case, no definite solution but the car was working. Less than a week later the car died again. I decided to bite the bullet and take the car in to Rola Motors in Strand, the closest Mitsubishi distributor. The cart sat there a week till they decided to send it in to another auto electrician. The car has now been with them a further 2 weeks and they think it must be the ECU but can't tell me anything conclusive.
Anyone have any suggestions? The car was working perfectly fine before I took it for a service?

Conrad,
Welcome to the forum.
There is a thread Pajero Workshop Recommendations with some recommendations. ANG Service Centre (Killarney Gardens) 0215562424 comes highly recommended, and look here for a guy in your area: M Saich Autoclinic as recommended bu Ned (McNoogle) of this forum.

I agree it is very far for you! Here in TZ and also in Malawi I am aware of many Pajeros with similar fuel system problems. They seem mighty fickle:(
I have attached a document I downloaded somewhere that another acquaintance used to solve his problem.

Thank you Anton and Brian for your feedback, and the warm welcome.
The ECU has been sent off to CT for repairs. I hope this sorts out the problem. If not, I will definitely take your recommendations into account, and will give feedback as to the eventual solution.
Kind Regards,
Conrad
