    Re: Help with Rodeo 2.8TD starting problem

    Hi all, new here so be gentle with me..
    Have had the same problem as mentioned above with the 2.8td fuel issue as to the bleeding hassle of a morning.
    Got onto a diesel injection mob who were real helpful over the phone, so it goes like this.
    The problem is in the seal on the shaft of the IP, as it heats up it expands and reseals, thus no more problem till it cools again letting air back into the system / IP.

    After trying new lift pumps, filters, stop valves, fuel line checks, i asked about a small low pressure electric pump, i was told this will do the job and it has done a wonderful job so far, no more cranking, bleeding, stalling, i placed the pump in the engine bay for easy access to fuel lines.
    I was told that they push better then they pull but adding the lift from the IP saw no real benefit to putting it closer to the tank.

    The electric pump i used was the Facet 4-7psi, now that this bandaid has been in place for the last week i have had no problems with the above mentioned problems...however, i will ring the mob again soon as i can to ask whether of not the small amount of pressure will force fuel into the sump passed the seal if thats possible through the IP shaft, i was told that because its sucking in air it wont leak as fuel cant escape where air is being sucked in, this be my biggest concern by using this work around, now by using a pump im worried about the pressure even though its small?
    As it is now the deo is running like a bought one.

    PS. no gauze filter in the IP feed line, but as its similar to the courier it may well have had one before my time of ownership.

    I had the same problem on my 406.....cranking for 40 sec till it started, then fine all day. The fix was to fit a non return valve in the fuel supply line just before the injector pump, after any fuel filters. It seems the N.R valve in the pump had failed / was stuck slightly open. I dont know if that was a bio issue. To check it, clamp the fuel line overnight to stop fuel running back, and in the morning try starting it. Obviously it wont run for long with the line clamped, but it may prove if that's the problem.

    Hi Toey

    Just wondering how your Facet 4-7psi electric pump was going and was it still fixing your air problem? Also, was wondering whether u gained an answer regarding whether the small air pressure would force fuel into the sump passed the seal if thats possible through the IP shaft??

    cheers

    Re: Help with Rodeo 2.8TD starting problem

    Hi FB, sorry for the delay in responding to your question.
    The pump is still working fine with no ill effects as to fuel in the oil.
    I mounted the pump in the engine bay for the purpose as to whether or not it would fix the problem, it worked very well and is still doing a great job.
    The pump is better at pushing then it is at pulling, but id rather it in the engine bay, its neat and tidy and is able to be kept an eye on.
    As for the air leak, it seals off after the seal reaches a certain temp and returns to normal operation, you could have it set on a timer to switch off after a certain period but since its a low pressure pump iv not bothered with it nor have i installed a switch to turn it off after operating temp is reached.
    Hope this helps.

    Re: Help with Rodeo 2.8TD starting problem

    Hi Narrawa

    Thanks for the post and the pm.

    I have had the facet pump installed for nearly a week now and the rodeo
    has been running like new. It is great.

    Before all this (ie fitting a pump) I did have a non return valve located in the return hose from the injector pump. The problem was not solved.

    I then fitted the facet pump - before the first filter (from the fuel tank) and placed the non return valve between the facet pump and the fuel tank. It works beautifully now.

    I have even tried to start the rodeo several times now without using the facet pump at all and it seems to be working ok. So, perhaps the current location of the non return valve (ie between first fuel filter and fuel tank) may have solved the problem. If so, does this still indicate a seal air leak in the injector pump?

    It may still prove that i need to use the pump, but at this stage the non return valve is doing the job,

    Cheers for your help - a very happy customer here

    Before all this (ie fitting a pump) I did have a non return valve located in the return hose from the injector pump. The problem was not solved.

    Not sure if i mentioned it in the PM to you, but if the none return valve is placed on its own at the IP, it wont solve the problem of air leaking back past the shaft seal over night.
    From what iv been told as the shaft cools the seal shrinks causing air to leak past the shaft seal again, but will only go as far as the return valve, hence the reason it did not fix the problem at 1st, just as in my case as well, best to have the valve close as you can to the IP, not so much air to bleed out once started.
    Its not totally clear to me either but after the installation of the pump iv not had any problems with it again, i check it regular to see if there is any foul play going on with fuel in the oil but there is nothing present.
    What i can tell you is there is some pressure now on the line from the pump to the IP its not much but its there, it could have something to do with it.
    One would think if there is pressure then it would leak past the seal when it shrinks.
    I was told that this workaround is nothing more then a bandied fix, & the real problem will catch up with you one day...Scary thought hey
    I was thinking of placing a fish-tank T piece in the line with a very small diameter hose on the ouput side of the pump & routing this to the return line to the tank, just for safe measures, but as there is no sign of fuel leaking into the sump/ ground/ or anywhere, im happy to just leave it be.
    Till enlightenment

    BTW, i use the lift pump from a late model mazda brovo, / ford courier on my 97 dao, but have now never had to use it. Thinking of scraping it & replacing lift pump & filters with a duel CAV filter system.

    PS. I guess i should add that even though this fixed mine & maybe a few others problem that was 1st described, there are many causes of air in the system, & this bandied wont fix all.
    I spoke to the mechanics of three holden dealerships from in & around my area to gain some insight to this problem, there answers were that they just change the lift pump & do a full bleed to the system.
    Quote on a lift pump was $300+, then labor to fit it.
    By the next morning the problem would have been back, but i would have been short around $400+ by the time i took it back stamped my feet & yelled misdiagnosis.

    To be fixed properly... its $400 for mechanic to R&R IP pump, $1100 for IP overhaul including a new shaft by IP specialists.
    Knowing this because i spent an hr on the phone with one, thats how i found out about the facet pump workaround.
    Hope this info helps some.

    Cool Re: Help with Rodeo 2.8TD starting problem

    Hi,

    I have had the same problem with my truck recently. There is another possibility some one suggested to me before, if you are low on fuel and as you go round a corner say, you might not have enough fuel in the tank and there is air being taken in the line to your pump. Sounds feasable, but then again this doesn't explain why it happens on 3/4 full tank.

    There is a great cheap fix I have found out, it works for me and might not for different vehicles. Park the vehicle facing down a slope/incline. This seems to cure the problem as the air bubbles I think are venting back to the tank. Face it uphill or on the flat and the bubbles seem to be there next morning. I have a clear fuel line in the engine bay and can see them form in it before it bends down to the pump.

    Hope that helps :-)

    Re: Help with Rodeo 2.8TD starting problem

    Hi Guys. Sorry for the delay in getting back about this. I ended up selling the rodeo and the buyer later told me the issue with the vehicle was the general timing was never done correctly from built, so that was the sum of all my problems. He did a few things and the car is running sweet. So, bio is cetainly okay for the 4jb1 TD rodeo in my experience. it all worked out well in the end as it was time to change cars for family reasons and time. Cheers FB
