2005 L200 starting problem

#1 by Maddogtrev , Sat Jul 13, 2019 10:30 pm

Hi just bought my first L200 its a 2005 Warrior only owned it 2 weeks the last owner a lady owed it since 2012 only done 87167 miles I really like this truck but its also driving me mad when starting from cold it turns over a dozen or more times before it fires up the lady I bought it from told me she had to give it 2 or 3 heats to start it so assumed it would need glow plugs. She also had never had a timing belt changed and she had it from 45000 miles so I've done the following since I bought it

New timing & Balance belt ( the balance belt that came off was all cracked around the outside and the timing belt was Mitsubishi think it was on from new)Both replaced with Gates belts
All auxiliary belts changed again replaced with Gates
New water pump and gaskets new antifreeze
Changed Oil & filter

Because of the starting issue I changed the glow plugs with NGK and cleaned the buzz bar all points of contact cleaned with emery paper and tested the relay etc the plugs that came out are NGK too and when tested work fine I'm confident that the glow plugs and all associated relays etc are fine and the heat sensor for them works too as when the engine is hot the glow plug light dose not come on.

At this point I thought the diesel could be running back to the tank so today I fitted a none return valve between the tank and the filter so hopefully the diesel can't run back.
Then tonight took the truck for a good run out a bought 40 miles starting from cold it was a bit spluttery as it pulled the diesel through which I expected I thought the run out would get any air out of the system etc
The truck drives better with the new timing belts etc pulls like a train much better power and acceleration.

Now comes the annoying bit that is driving me mad if i stop the engine when its hot for 5 minutes it fires up straight away if I leave it 10 to 15 minutes it tunes over half a dozen times be for it fires up so I'm assuming in the morning when its cold it will take the usual dozen or more times turning over to start as nothing appears to have made a difference.

I'v read a lot of posts on this forum about this same issuer but feel I'm missing some thing or is this the first sign of injector pump failure
I would really appreciate some help with this please

mine was similar ,or sort of ,start first time everytime in the morning , but then after a drive if I stopped it would take a few cranks to fire up and a load of smoke out the back , just had the head gasket done ,and the issues are still there albeit slightly different , now it starts but wont rev over 3k , then all of a sudden it seems to clear and revs freely again , I also had a non return valve fitted just before the thingy on the right as I think that was on its way before the head went . I might change it for a new one and see if that helps as the non return was the easy fix ,engines great now all the timing is spot on just this one small niggle now .hope you get it sorted soon

check the fuel lines the complete length could be drawing in air

the stack pipes on these trucks like to rot for a pastime
fuel pump failure is fairly uncommon
timing being out a tooth happens sometimes after a belt change but unlikely if your truck is running better than before
the bottom pulley delaminating does happen on these engines
have a look down from above with the engine running and see if it's wobbling
then with the engine off see if there is any play, if there is, stop driving it immediately and get it replaced
there were some fake NGK plugs being sold on ebay for a while so if that's where you got yours from it's something to consider
fuel filter ........ many faults on these trucks can be cured by changing the fuel filter
even if it's only just been changed, for the sake of 15 quid for a brand new genuine mitsubishi filter I'd be doing that
pump the primer on the fuel filter housing, it should pump up and stay hard (oh-er) , if it goes soft again then air's gettin' in

Hi Krutly
I can't see the stack pipes that well but don't look terrible the fuel pipes visually look ok
The bottom pulley runs true and when I did the belts I was happy with the overall condition and had no play by hand
I'm happy with the timing of the belts as with the better performance
The NGKs came from a local motor factor I'm happy that the glow plugs and associated system are working fine

The Fuel Filter the filter is a MEYLE products made in Germany part No 32-14 323 0001 and can be bought on ebay for £9.41 free deliver and mine looks new. So on Monday I will go to Mitsubishi and and take your advice and fit an original
when I put the new one on is there any thing in particular I should look for fault wise.
I've pumped the primer and it dose get hard but the next time you go back to it after about 10 minutes it soft again.
I'll try changing the filter and try to get a better look at the stack pipes
Thank you for taking the time to give me this advice I am diesel fitter but I have no experience on the Mitsubishi L200 and as the guy I served my time with used to say( You Can't Buy Experience )
I will let you know what happens with the filter etc Thanks Again

when changing the fuel filter , I usually put a smear of diesel round the seals first then replace the drain valve, half fill it with forte injector cleaner then top it up with fresh fuel before replacing
never done it more than hand tight, usually a few pumps and it's solid
bit of an 'italian tune' once it's started to blast through the injectors and job's a good 'un

Only way the primer can go soft all the time is air getting back into the system somewhere

Time for an update
So today I could not get a Mitsubishi fuel filter my local dealer doesn't carry much stock evidently
So I sourced a Bosch fuel filter from a local motor factor I took the complete filter housing off removed the old filter and cleaned & inspected the pump and housing all looks ok fitted the new Bosch filter put it back on the truck I have a none return valve on the line coming into the filter so only took about 8 or 9 pumps to prime the filter and a couple more to bleed the air out the filter.
I started the truck and let it run for about 15 minutes then turned it off and left it for an hour came back full of anticipation and it took half a dozen turns to start. ( bugger )

So for my next trick I got a gallon ( or 4.5lts ) of diesel in a fuel can and 2 lengths of fuel pipe 8mm inside diameter for the feed and 6mm inside diameter for the return and new hose clips of the appropriate size
So now I can run straight from the can to the injector pump it took about half a dozen turns to prim from the can to the pump and again I ran the truck for about 15 minutes and turned it off
I had my tea and a shower left it about an hour again and tried to start the truck once again it took half a dozen turns to start up so I'm assuming that it sucking air from between the injectors and the pump.

I'm assuming that if it can suck air in it would also leak diesel out when I shut the engine off but there is no sine of a leak the injectors are dry and the leak back pipes look dry as dose the injector pump.
Has any one any ides were to look next I've spoken to the local diesel pump reconditioning guy he thought that it was unlikely to be the pump at 87000 miles
Any help would be greatly appreciated right now as I still feel like I'm missing something

Any white smoke or lumpiness in tickover after the initial long startup?

When it starts after a dozen or more tuns from cold there is a very small amount of white smoke and settles to a smooth tick over when its hot and only turns half a dozen times there is no smoke and good tick over

So you're getting unburnt fuel then. Could be something along the lines of an overfueling / bad pattern injector or even a leak from the injector base seal. Neither would show an outward leak but would allow air in. Any slight "ticking" noise around injectors?

To be far I would expect a small amount of white smoke from cold as by the time it fires up the glow plugs will have cooled a bit and no there is no ticking from the injector

Well I feel I have exhausted all possibilities I can't find any leaks and have had a code read and there were no codes present.
I've added a none return valve between the filter and the injector pump and seen a slight improvement it starts better when its hot but park it and leave it any length of time and it turns over and over half a dozen times and the same when cold.
I have spoken to a local diesel injection specialist (Breedon & Gell ) in Darlington were I live and they can bench test the injector pump so I think I'm going down that rout next.

When I put my clutch pedal down to the floor the engine revs drop a little and come back to normal when I take my foot off again why do you ask ???

Maddogtrev - Peter R do you realise you have different model trucks
Trevs - Classic
Peters - Pram
So the cause could be totally different issue.
Just a thought!

Latest up date been out in the truck to day when I came home I clamped the return pipe from the injector pump and switched off the engine I clamped the pipe 4cm from the outlet on the injector pump the inlet to the injector pump has a none return valve 4cm from the injector pump so I effectively trapped the diesel in the injector pump. I left it parked up for about 6 hours when I came to start it again it started straight off the key no hesitation.
So would I be right in thinking that because I stopped the diesel from running back from the pump that no air could be drawn in as when I left it half an hour without the clamp it turned over half a dozen times before it started and would this point to the front seal in the pump been duff????

Has any one changed the front seal without taking the pump off by just removing the drive pulley on the injector pump and digging out the old seal and pushing the new one in ??????
