To repair / overhaul injection pumps is well beyond the scope of the home mechanic. Take it to a local specialist. |

Hi Rik,
don't bother messing with the diesel pump - it's very complicated and requires special service tools not to mention specialist knowledge.
Much better off taking it to a Japanese diesel injection specialist. Or even better a commercial diesel injection specialist - as they tend to be much cheaper. _________________ 1991 L300 Delica Super Exceed |

I replaced thottle o ring and top seal, got a complete set of seals from local Lucas outet - £11.00 for set.
But I could do this without altering any of the settings, as tricky and hysterdoctor say you need to know what you are doing to completly overhaul pump.
Check pocuk club site for more info, do search on feul pump.
For details of the repair I did see:

Think twice before doing overhaul and good luck.

Hi All,
I also have a problem with my 2.5 td injector pump, It seems to be giving to much fuel. the fault happened suddenly so I presume a seal has failed. the Delica runs fine but is making to much smoke and has little chance of passing the MOT like this.
Does anyone know if there is a site or can anyone email me a scan of there workshop manual of how to check and service the fuel injector pump on a 1989 Mitsubishi 2.5 TD (Mitsubishi Delica - Should be the same as a L300, L200, Shogun or Pajero)
TIA, |

There really isn't much you can do yourself to the pump. The pump is usually the most reliable part of a diesel system, so I'd look elsewhere first.
Is the smoke black or blue? If black its overfuelling.
1. Is the airfilter and intake clear? Is the turbo working?
2. Are the injectors working properly, the spray can be checked by removing the injectors one at a time, inverting them and re-connecting the to the pipe. Crank the engine and make sure that the spray is correct and that it shuts off instantly. KEEP CLEAR WHILST DOING THIS, DIESEL INJECTED INTO THE SKIN CAN KILL!!
3. Check the pump securing bolts, if loose the pump may have moved, altering the timing.
To strip and rebuild the pump is a specialist job, even the main dealers put this work out to the specialist repair companies.

first off i would not recomend testing injectors like this,have it done properly and don't run the risk of serious injury. anyway thats enough of my health and safety lecture for today :? , check your bottom pulley! run the engine and see if it runs true, if not take off your fan belts and see if you can twist or wobble it, i had a 2.5 shogun in today blowing some severe black smoke with a knacked crank cos the woodruf keyway in the crank had worn into a v groove poss due to a loose pulley bolt and vibration of engine. anyway i am going on a bit and it is a deer repair so i hope it is something less serious |

Was it the keyway for the cambelt/pump drive pulley? I assume that the black smoke is caused by the pulley rotating around the crank and altering the cam & pump timing. |

The smoke is black. Sometimes great clouds of it but other times none at all, usually there is enough smoke to notice it in the down view mirror on the back.
The problem started with a "bang" on the M6, The AA man could find nothing wrong and suggested I drove home slowly, which I did without trouble. The local garages could find nothing wrong and since my last trip to a Mitsubishi dealer cost me £1400 I don’t fancy that again! On some occasions there is nothing wrong so the fault is not likely to be something mechanical broken. I drive it around every day and the engine runs fine except for the smoke and the rattling noise that all diesels make when cold does not go away. The local garages who cannot find what’s wrong have suggested it might be the fuel pump. I have been quoted £300 + labour and vat to get it serviced. I replaced the bottom pulley a year ago as the rubber had broken up so it is not likely to be that but I have not checked it yet! I had a look around myself and made sure all the connections, bolts and hoses were okay and it seams to have improved slightly. |

If that includes removing and re-fitting, its a good price, although the cost may rise if they find worn / scored parts inside the pump. If you have the pump overhauled, I would recommend having the injectors done at the same time. |

the £300 is just to send the pump away to get it serviced the removal and re-fitting is extra |

Still not too bad a price, I had a pump overhauled a month or so ago, that had water run through it and it was nearly £900. |

There was a pajero diesel pump on Ebay last week, I spotted it at the last second, too late to bid on it and it went for £20.00 !! Gutted !! |

2. Are the injectors working properly,
3. Check the pump securing bolts,
Chris
Thankyou Chris for you help I have today started to have a look to see if I can find the problem based on your suggestions.
1. Air filter okay, pipe to turbo from covered in oil on the inside
2. not checked yet.
3. turbo spins okay but is covered in oil inside and out.
is this normal?
Thanks,
Stuart. _________________ Take your time to get it right.

okay Stuart, I'll try to help further, but it probably gets difficult from here on in, I have worked on diesel engines for the last 15 years, but have no 'hands on' experience of the Mitsubishi engines. So any advice / info is based on general diesel technology, rather than specific knowledge.
I'll have to look tomorrow (Monday) evening at my Delica and see how the engine breather system works, this, if it feeds back into the air intake system - as do most modern engines - could be the cause of the oily deposits. Two reasons for this, one simple & cheap, one expensive :-(
First and hopefully most likely cause, is blocked / oiled up breather valve, this can cause excessive draw of oil mist from engine into intake, second and most expensive can be excessive crankcase pressure (worn rings / bores) forcing the oil mist into the breather system.
I'll have a good look at the Delica system tomorrow evening and try to narrow down the likely cause.

Thankyou Chris,
Do you have broadband, if so may I e-mail you some pictures of the turbo and engine. if you are on dial up it would take ages as the files are large and to reduce them would loose the detail. _________________ Take your time to get it right.

Aye, 1.5MB broadband, so pics will be no problem, it may be worth posting on the POCK forum, just in case it turns out to be a Mitsubishi specific problem, that is known. If not we'll do our best to get to the bottom of it, although sometimes the only way is to get hands on and look & listen.
