Could be the cold-start valve or connections .... maybe even injectors that are dirty. :think:

Welkom Jacques,
My 2,5 doen dit al vir 5 jaar, ek het maar vrede gemaak daarmee. Dit word nie erger nie, dis net irreterend partykeer. Hoop iemand kan jou se, ek wil ook weet.

I also heard that it could be a lack of compression from the pump could this be true that unit is very expensive somthing like R.13000, what i did the other morning was: I pulsed the starter about 4 times and when is swung the key the 5 time it started 100% no problems and as i said there is no smoke out the exhaust.

Maybe that the glow plugs are a bit weak. :think: I doubt that it's the diesel pump not delivering enough pressure, otherwise you would have a problem after it starts as well, especially at higher revs. :think:

Maybe the 'diesel heads' here on the forum can offer some better advice. ..... Allan? :eh:

ok guys problem resolved
this has to be the stupidist thing ever
Dastek and toyota said it was the the diesel pump after spending 4 000 rands removing glo plugs cleaning the egr valve and the intake the fault is so simple.
on the diesel filter there is a small tap loacated at the bottom, it turns out that the o ring seal was broken on that tap so i was loosing diesel pressure, i replaced the o ring and my bakkie is starting 100% again thanks for all the support guys.

Good to hear that you got it sorted, and that it was not something major. A good tip for all the other diesel owners out there. :thumbup:

Jacques does this happen when cold or warm or both? I'm leaning towards weak glow plugs if it happens when cold.

Just a quick note on the price question. The price of R13k is roughly correct. Diesel pumps are quite expensive.

Only when it is warm. When I drive for long distances and I shut it down and try to start it in 10min time it takes a long time to start. When it is cooled down a bit it starts easily. :punch:

Jacques, ek het op die oomblik dieselfde problem met my 2,5 d4d, dat hy moeilik vat as hy warm is,het die diesel tank afgehaal en die filter binne vervang en n nuwe diesel filter ook ingesit en die tank skoongemaak en injector cleaner op 40l skoon 10ppm diesel ingegooi en 200kms gaan ry.
Maak nog steeds so, as ek hom pomp op die dieselfilter dan vat hy maklikker of as ek die sleutel n paar keer (drie) aan af skakel met draai ,dan vat hy makliker.
Ek vermoed die pomp het nie genoeg suigkrag nie,daarom vat hy moeilik net as motor warm is.
Sal n een bar pomp binne in die tank help hiervoor inplaas van om die pomp te vervang of herstel? Is daar enige iemand wat my sal kan help met my probleem?

Op die dieselpomp is ñ soleniod. Hy maak vas met 2 allenkey boute (5mm). Haal hom uit wees versigtig daar is n gasket en o'ring . Daar is ñ plungertjie voor maak seker hy is nie hakerig nie. Op die ouer modelle kan n mens die plunger uithaal deur n klein circlip uittehaal.
Moenie enige skuurpapier of iets grofs gebruik om hom skoon te maak nie. Die plunger is deel van die suction control valve wat die diesel druk beheer

Dankie Jan, het hom afgehaal,skoongemaak,maar nie enige dadelike verbetering gekry nie.
Maar daar is n geringe verbetering nadat ek n paar honderd kilo's gery het met die injector cleaner.
Hoop dit verbeter nog, anders weet ek nie wat verder fout kan wees nie.

Janee die uiteinde is toe dat die pomp vervang moes word, en ons glo die oorsaak van die pomp se agteruitgang was vuil en hoe swael inhoud diesel oor n lang tydperk.
