1kz-te engine sounds sick and sporadic odd knocking (2 Viewers)

Hi Crusher,
The 89661-60250 is the correct ecu for your model, the 89661-60520 is for the 90 series prado, you may have problem with it. The ecu from KZJ78 manual box is different and would not fit coz it is of different connector. 89661-3D100 from KZN130 surf would work but you will be missing overdrive gear.

Hi Crusher,

The ecu from KZJ78 manual box is different and would not fit coz it is of different connector. 89661-3D100 from KZN130 surf would work but you will be missing overdrive gear.

So you are basically saying the 90 series ecu would work on a 70 series; refering to A/T?

I have been informed this is the case. I was on the verge of ordering a M/T ecu from Japan to for on my 70 series, which is manual. My fault was traced to an aftermarket turbo timer I had installed.

In Malaysia, here, its quite common for the ECU's to be repaired by replacing some of the capacitors and resisters on the circuit board.

I don't know if the 90 series M/T ecu would plug and play on the KZJ78. The part no is different, so do the sensors. The wiring may not be similar. What I have tried the KZN130 A/T ecu would work on the KZJ78 A/T, but you don't have overdrive. To be safe get the exact ecu for your applications.
The M/T ecu may not be that difficult to figure out as long as you know the pin configurations. Afterall its the same basic engine. Its a good experiment, the hiace and granvia ecu are quite easily available at the breakers.

How are things going with this truck? Ever get it all sorted out?

 

[crushers]

not yet, i still want to convert to manual pump, owner wants to try and source the electrical issue.

i love 1 wire engines. simple, reliable, long lasting and cheap.

 

[gotoy]

Are you sourcing for ecu and fuel pump?

 

[crushers]

KZ had the ECU "repaired" in the states. no response as to what was wrong but $250 later it was back and still running like s***.
KZ is thinking of sending the pump somewhere for a full rebuild.
I am thinking it might be a waste of money and am pushing for a manual conversion.

or

we stick a 4.7L toyota gasser in ... ???

Like Crushers said, ECU tested and 'repaired' so this leave us with the IP. My friend, who actually owns the truck but isn't a mudder, would prefer to keep this truck as stock as possible.

So, the question to our international and especially Malaysian friends since these truck seem to be a plenty in your part of the world, how readily available is a used but proven 1kz-te injection pump?

I do have a lead on a diesel shop in Southern California, BEC's, that just rebuilt one of these pumps, sensors and all. They have cross referenced all the parts with Denso in Japan and the customer has the truck up and running again. Looking into that as another option as well.

last time i looked i thought the truck had roots spreading downward from the frame. i am begining to think i might have to let the wife turn it into a green house ...

Nah, wouldn't work ... tinted windows.

But seriously, I do appreciate the patience Wayne.

Pity you are not down this end of the world. The diesel specialists down here do manual set ups for the 1KZTE and also can overhaul the Electronic pumps.

I've done a couple 1kzte conversions into vehicles here in Southern California, I have personally used BECS Pacific, the earlier mentioned company, three times and am VERY pleased with their service. I sent 8 injectors and an Injection Pump to them, all were sent back better then factory! The Ecu Repair was going to be my post, up until I read on this last page that that had already been done.

Have the front timing gear bolts been checked, Timing spot on? Also, what type of gearbox is in the vehicle again? I would recommend the customer have the injectors and IP sent to BECS, Definitely worthwhile. They'll bench test the IP and pop test the injectors. Were the fuel lines ever crossed up, a fuel line traveling from the IP to the Injector is crossed with the wrong injector, will make horrible knocking noises. I've messed that one up on accident!

Just trying to spit out some ideas, as I know how frustrating it can be to chase your tail with these engines!

Turbo 3.0L Injector Pump drama 2003 Hilux!

Hi guys!
Reading the story is quite interesting indeed - be it somewhat frustrating for those involved!
My son has a drama with his 2003 Hilux 3.0L turbo running the electronic IP (1KZ-TE?). Filled up with some bad fuel. What occurred was as running down the highway (in far North Queensland) the engine lost power and cut out. He dropped back thru the gears, and it restarted and ran another 10 miles before cutting out again. On the tow into town, tried the 'clutch start' again for quite a while with no restart.
On investigating, found the in line filter collected what looked like water - quite a lot. Tank and all lines flushed thoroughly.
Fuel is delivered to the IP, but none comes out the other side. Has been told by mechanic the pump will need a full rebuild = Huge $$ + 8 hours to R & R.
Q's: Would this be enough to kill this pump?
Any way to 'clear' the pump if it is an internal block, or is it a sensor that will have shut down?
Change the pump over to a manual version?
Any feedback would be much appreciated as the Lux is hundreds of miles from 'home' and the bank account lacking!

Bump, has that used kiwi fuel injector pump been fitted yet?

 

[crushers]

Calvin,
not yet, i need to get the troopy done so i have space in the shop.

thanks for helping a brother out.

plus, with the RHD insurance issues ...

Perhaps it time to convert the 1kz-te to a mechanical fuel pump and be rid of the ecu.

A good colleague over in Sabah, Malaysia, recently used a 13bt fuel pump. 3b fuel pump could also be used. Or a any other fuel pump as available, could also be used.

That was recommended by Crushers. The owner, a friend of mine, wanted to keep the vehicle as stock as possible.

Either way, we have a used 1kz-te pump now, it's just a matter of finding the time with Crushers. With his troopy build, I am rightfully in the back seat.

mechanical pump cony on prado

recently did a 2L-T mechanical fuel pump conversion on my 2L-TE motor.

Works great! got rid of the dreaded fuel cut. Running 22lbs of boost on the stock ct-20, likely very inefficiently. Added large water meth nozzle, to keep the egts in check. Funny thing is you can really feel the water meth, if i'm at full boost and flick the switch it surges forward and give me 2 more pounds of boost. Never seen such a gain from water meth, must be that the turbo is just blowing out hot air at that psi.

Anyways like a 2L it likely has as head fissure. cause I can't keep my cooling system from not becoming over pressurized.

So here comes a new head with a port and polish job, and a used holset hy35. I'll let you know how it goes.

Totally recommend the pump change to anyone

wow im impressed but 2LT and reliability and performance is a big of an oxymoron isn't it. If I did this 2 a 2LT I owned im sure I would have a spare HEAD and gasket in my tool kit permanently

Hope the new head lasts.
