diesel 3.0lt having trouble starting - any ideas?

Unread post by simsy » August 26th, 2012, 5:42 pm

Hi all, my mate 99 3lt jackaroo is having trouble starting first time for the day.

he has to lift the bonnet and manually pump fuel through before it will start. i think it then smokes a little but is fine for the rest of the day.

we're in brissy and looking for anyone who has had the same problem fixed and who did the work please. as a few diesel shops we've contacted don't want anything to do with it. apparently it's a complex motor to fix.
cheers

Make sure your running the right oil, has to be 0/30 grade not normal diesel oil (if anyone tells you different, their full of sh#t) or the injectors won't work properly, they run a "Cat" injection type of system which most mechanics don't like.

I agree, I had an 02 3.0l Jackaroo until late last year. Motor had about 100, 000 kms on it and performed well. I had the car serviced once and tried a new oil in it. Within a couple of days I noticed that the first startup of the day was becoming an issue, but the car started fine for the rest of the day. Problem was fixed by putting the original reccommended oil back in it.

thease engines need oil pressure before they will produce any fuel pressure and i have seen a few of thease engines crack the injector pump oil pick up in the sump and theu suck air causing poor fuel pressure try over filling the engine with oil be about 250ml of oil and if this fixes it you may have a cracked pickup

I have 2000 3.0 td and had the same problem as you do. I had to prime it every morning to start it. the problem may get worse if you don't fix it soon. try changing your oil to 5w30 or 5w40 and replace the oil filters - remember there are two. the main oil filter is the big one on the drivers side and the high pressure one is on the passanger side and is a bit messy to do. the other thing is you may be losing pressure in your fuel line. but in my case, my jack had the recall in 2006 and the seals were done, but who really did it and did they lubricate the orings and sleeves before they reinstalled them? no i don't think so, as the bottom o ring was cut off and sitting above the o ring slot on all 4 sleeves. just lately, I discovered this was also to do with diesel in my coolant, the diesel started to soften my coolant hoses, popped a hose in the middle of nowhere as further than 10ks from anything and overheated the engine. now I have another head on its way. I know more about this 4x4 than any other car I have ever had and it wont beat me, I will pull the engine out and start from scratch if I have to. in saying all of that, I love my jack and wont part with it. thanks for reading.

If you think that there might be a leak int he fuel line then add a $5 one way 8mm valve just before the fuel primer filter assembly. If its still needs priming, then the primer filter assembly is leaking air - not uncommon. Also ensure the fuel filter is screwed on tight as I have heard other blokes using non ryco Z321 compatible fuel filters which have a slightly different shape near the screw thread and it doesn't allow the filter to tighten properly onto the housing, so if its not a Z321 or a very good Ryco clone like the sakuras, then the filter can be the fault.
I only know what I know, so if I don't know, I'll let you know.
