Fuel Injector Problems ???


I think your problem is probably a blocked fuel filter , or something similar , Marj. Hopefully shouldn,t cost too much, but Pelay's injectors could be a more serious problem . Diesel fuel systems operate at much higher pressures than petrol motor, and even higher if you have a common rail type systems. These run at thosands of pounds pressure!Pejay, what type of motor is in your nissan?I hope its not too major. Bill

Well it's been an interesting couple of days with more to come. Last week had 'The Beast' serviced ready for taking off - no worries! smile  On Friday morning having done some driving around to get a few things etc (as you do) I got home in time for lunch - beast going fine, but then after lunch Pete hops in to head up and put his Lotto on (blimey, don't we need that now!) and 'the beast' - it spat the dummy!! no  Got RACQ out and it got towed up to our mechanic for check up - not happy, only to find it could be fuel injectors and it will need to be towed down to a diesel place some 50 kms from home, AND a hefty bill possibly into the bargain!! Rang RACQ again when Pete came home, organised the second tow for tomorrow (Monday) morning, and a hire car for 3 days - would have been longer if we had been more than a hundred kilometres from home!! Wasn't even a hundred steps! It was in our driveway.

So .... looks like we have had our 'travelling wings' clipped for a while, but we will know more tomorrow, and reassess the situation then. Loook out for part 2 tomorrow!

What a bugger Pejay, always the way isn't it?
I have to get Myrtle checked out this week when I can get her booked in. She's cutting out at intersections and chugging a bit up slopes. Something needs a bit of adjustment, hopefully not as expensive as it looks like yours is going to be.

I try to have any servicing on our tug carried out at least 1 month before we go on a trip, just in case something is done/not done on the tug that can impact our trip.

Catch up time - well it would appear it was nothing to do with the servicing, however we had the Patrol (3 lt turbo diesel) towed into a specialist injector guy yesterday and he can't look at the vehicle 'til early next week, and thinks it's either the fuel injectors (around $1500) OR the injector pump (around $4,500) - now which one we are hoping for! However, it has put our plans to head off on hold for a little while. But thems the breaks, and we obviously were not meant to head off at this time - for whatever reason! I gather it is one of those things that 'just happen' whether we picked up a dirty batch of fuel or what, we have the fuel filter on and it was changed when the vehicle was serviced, and we use a fuel additive which we know works - Pete used to make it where he used to work, so we know what went into it. Ah well, I guess one good thing to come out of it, is that I will get plenty of walking exercise.

If you can run the motor without damage, it pays to run some DIESEL injector cleaner, any brand , Wynns is good, thru the system, and change the fuel filter , whether it needs it or not.A little trick is to fill the filter up withe clean fuel , and put an air pump on the fuel filler inlet and pressurise the system, til you have fuel to the injector pump. Run the motor til there is no air in the system.I usually crack one of the fuel lines at the most accessable injector, and tighten when all the air is out. I hope that helps. Bill

Good luck for next week Pejay, hope its the cheaper option.
Myrtles booked in for tomorrow, Wednesday, to work out her problem. Thanks bill, I written down all the possibilities including your suggestion. The boss said to explain exactly what she has had done to her when I see the guy who will work on her tomorrow. Have also got all the receipts ready so they know whats been done.
Pejay, the positives are you will get plenty of exercise as you say. The negative is you are going to miss out on your camping trip, but there will be plenty more.

Hi Peter,

Thanks for the suggestion, is it a forum through Nissan by any chance - I have never heard of it, but am willing to have a look and see what they say.

Thanks Peter, will have a sticky. However just heard the bad news, looks like it is the pump - bother!!! (or words to that effect). Think I had better go by a Lotto ticket for this weekend's big draw.

Guess it doesn't really matter what type of vehicle you have, and no matter where you are, it is always possible to pick up a dirty load of fuel, and we watch where we buy fuel from, but sometimes - stuff happens, and I think this is one of those occasions.

Friend had a similar problem from memory $X,000 to have faulty items replaced with new, or for a patch up for $YK, he did the patch up and sold his Patrol because after that the job, was always wondering when it would breakdown again, and could not stand the thought. He bought a Prado. His patrol looked great/ tough and a great ride but.....

A few years ago on the Gunbarrel highway heading towards Wiluna, a 3L Patrol followed by his mate cannot remember the mates vehicle passed us going quite fast and left us in dust forever. On the CB asked him why the rush, His answer, wanted to get to Wiluna before his fuel system problem occurred again.

Heard that some patrol users have an additional filter system in line to cope with dirty outback fuel, but not sure if this 2nd filter will impact/dissallow warranty claims

In queensland last year, tanker unload fuel at a city Fuel stop, asked the attendent what fuel was big unloaded, Diesel was the reply, in that case I will fill up elsewhere, Attendent, upset at my comment in front of other customers said we have 3 tanks of XXXXXXXX in no way will the tanker stir up fuel in our tanks, anyway, whats to say that the tanker had just left down the road,. and furthermore we have never had any complaints. My comment, if I take on a load of dirty fuel I may not find out up to 500Km away from here in which case you will not here from me also.

Would you believe, heard on the radio when travelling south, a few daus later that a Brisbane driver was taking a fuel company to court because of an expensive repair bill to the fuel system of his European car.

Peter

be very carefull using this method on common rail diesels as the pressure is so high it can remove flesh

I was talking about older, non common rail diesels. I wouldn,t even try to bleed a common rail fuel system- too complicated.The good thing about the older style diesels is you CAN work on them. Common rail motor are more efficient and give more power, but can,t be worked on by the average bloke. Have you ever looked under the bonnet of a late model  common rail diesel.You have trouble finding the filters on the ones I have seen.Too much plastic for me. Bill

 When you get the vehicle looked at and the fuel filter changed get them to blow the fuel line out back to the tank with compressed air.

I had similar problems with my Hilux when we had it.

Injector pumps are a problem on the 3.0 Patrols, and that can cause EGT's climbing on #4 which causes irreparable damage to the engine if left too long.

Yes they can cost thousands to repair BUT if done properly by a company with experience with the problem, it should not happen again.

The was quite a few in the early series but the problem got mostly sorted later on so is not normally as much a problem.

Bad fuel is the number 1 cause of fuel problems on LPG, Petrol and Diesel vehicles, can get extremely expensive in the case of Diesels and is very hard to control as you generally don't test any fuel that goes into your car which caught me out just recently.

On a Diesel you can run water a separator and a good quality fuel filter, all can be supplied at any good auto shop and just run them inline where a normal inline filter would go.

Here is a kit from terrain tamer http://www.terraintamer.com/en/4wd-products/filters/item/207-fuel-manager or on Ebay out of the UK but this is what I run and all up cost less than $60 from Renhel in Dandenong http://www.ebay.com.au/itm/DIESEL-FUEL-WATER-TRAP-SEPARATOR-ASSY-CAV-296-FUEL-FILTER-ASSY-SUIT-GARAGE-/271031607537?pt=UK_CarsParts_Vehicles_BoatEquipment_Accessories_SM&hash=item3f1abe20f1#ht_1378wt_1163

Cheers Damo
