over the past 4 days i have had to call the RAC out 4 times because my Amazon (2000) stops running , some times it starts again on the key, and other times the RAC had to use easy start to get it going. it can run for 140 miles with no problem then cuts out.the RAC have recovered the car to outside my house, i turned the key and she started up again. the RAC think that there is air in the fuel that is causing the engine to cut out. if this was the case would she start up some times but not others.
can anyone help with any idea's.

There is a fuel cut solenoid on the fuel pump sometimes the wire comes loose or the power is interrupted and it will shut off the fuel.
Cutting power to the solenoid is what stops the engine when you turn the key off.

There was someone else on here with a very similar problem and the dealer convinced him it was the injector pump.
So he forked out for a recon pump $$$$.

Maybe a new solenoid would have fixed it;)

The air would be a more regular thing causing hard starts as the air leaks in slowly overnight.
Even when they have a leak they generally keep going once the engine can suck enough fuel through.
Air leaks are usually around the fuel lines to the filter or pump ,or the filter itself is not tight.


Im assuming yours is a diesel

Many thanks for your help, I have taken the 2 plastic covers off that hide the pump and found that there are 4  electrinic items on teh pump. i have tried wiggling the terminals to all 4 and it made no difference. i am not too sure which one of the wires / electronic is the solinoid.
car starts and runs fine at the moment but i am worried that i will get a mile down the road and it will cut out.

thanks again for teh information posted.

The solenoid is the thing the wires are joined to. It screws out. Sometimes a clean up can help.

Carry 3ft of wire with spring clamps on each end. Next time it cuts out connect the wire to the solenoid and + battery terminal.

have visited our local deisel specialist, who wasn't alot of help. He informed me that you cannot replace the stop solinoid on my pump as the pump has to be stripped out to get to it. I am not sure what one of the 4 electrical plugs work the solinoid, there is a plug on the side of the pump where the fuel comes in , one above that , another one on the side of the pump near the injoctor pipes and another one above that. also I do not know what would be the positive side to conect a wire from the + battery terminal.
any help most welcome

Robert

[roscoFJ73]

Rob ,I hope I am not leading you astray as I have an older model,non turbo and yours may have a different type of solenoid but I thought the basic functions of the pump would be the same as they are both Nippondenso rotary pumps.

Here is a pic of mine

my pump is simular but not the same, there is a plug with 2 wires that attach to what I think is the solinoid. a red and green wire.underneath this there is anotehr electronic item which a mate of mine reconed was the fly by wire accelerator sensor. Is it possible to change the solinoid yourself or dose the pump have to come off and be rebuilt, the deisel specialist looked at a picture and said you will need to bring the pump in for a rebuild.
many thanks for the help so far

Robert

[roscoFJ73]

The solenoid on mine screws out as mentioned before.
How many klms/miles on this engine? The pump should last a 150000 miles minimum.

I think you have an electrical problem that shuts down the pump ,not a worn out pump.
The reason I say it is electrical is because your problem is intermittent.
Pumps that need rebuilds lose power when hot or run rough and they do it all the time because they are mechanical.

Normally fuel injection pumps that are suspected to be worn ,are removed from the engine and fitted to a machine that simulates its being used.
Sensors measure the pressure from each injector line.

Given the fact that your specialist has the benefit of seeing the pump and deciding it needs a rebuild,he should at least be able to tell you which parts need replacing.

Had a very similar problem with mine, put up a thread on here about it and all of the above suggestions were given to me and checked but none were the answer. I brought it to my local main dealer, no good, plugging in didn't show up the problem, brought it to a diesel specialist and he hadn't a notion. Eventually brought it to the city dealer hoping they would have an idea after being recommended to go to them, and within hours it was fixed. I don't know if the problem is the same or not, but on mine there was a wire damaged going to the fuel pump as far as I can remember, and this is what was causing it to cut out randomly. I could drive 10 miles and it would cut out, start up straight away and not have the problem for another 200 miles, then have the problem and not able to start at all.

Check out the wires for damage and if there is any, then thats your problem.

Hope this helps.

Visited my local Toyota Dealer near Sandhurrst, They said that it might be the ECU that is playing up. This might sound a bit ignorant but what is the ECU and what dose it do? If i can get the LC there they will put it on their diagnostic machine. if this dose not show up any problems thay said they will start changing parts. sounds expensive. Can anyone tell me what the ECU dose and is there any way of telling if it working ok.

The ECU is what controls everything. They rarely go wrong, and it's the last place to start looking for problems. Is the Engine fault light on? If not, there are no faults stored so their computer will tell them nothing.

Have you tried the suggestions you've been given here?

Save yourself a whole heap of money and buy the Toyota manual, there's a huge section on trouble shooting the pump, and you will know which solenoid/wires do what, then you can check out the basics at least. The book will cost you less than 1 hours labour. Don't know how much an ECU is, probably a grand or so. Have you tried Vulcan motors in Sandhurst? Nice little garage and you can speak to the owner or his wife. If needs be, buy the book and take it down there and ask him to go through the trouble shooting section.

My money is on something basic, like stop solenoid or wiring, maybe ignition switch. With the book you can check them all out in a few minutes.

Hi
Many thanks for the info. i will call into the Garage you have sugested and see them. I am new to Toyota LC and do not know where to get a repair manual  / book from. have not had much luck in locating one.
thanks again

Robert,  I would agree with everybody who has said this is an electrical problem.  I would bet big money that the power to the fuel cut solenoid is being interrupted, but the big question remains - what is causing the cut?  It could be a damaged wire, but I would also look at the anti theft system.  Do you have the Toyota anti theft system fitted?  If so, there is a transmitter fitted to your ignition key which communicates with a small receiver in the ignition barrel, and the whole lot is controlled by a small computer fitted behind the glove compartment (separate from the ECU).  If that system is faulty then it will instruct the fuel cut solenoid to shut off the engine.  I have not yet removed the plastic covers on my injector pump (you have the 1HD-FT or FTE engine, right?) but I read somewhere that it's not a simple matter of just supplying power to the fuel cut solenoid directly from the battery as you could do with older engines - to make it harder to bypass the anti theft system of course.  Anyway, look forward to hearing what the solution is!

[robert norford]

 the landcruiser has been at Vulcan Garage for 2 weeks now. I spoke to them today for an update but they informed me that the car has been running fine and has not cut out since they have had it. They are using it to collect parts etc but so far no problem.  Typical of my luck.
