Engine cut out after service




Hi guys…I seek for some advices please

Problem : after an full service (oil/filters)

I need to mention this: after I changed the fuel filter I didn’t primed fuel into fuel filter as it was first time for me when I changed the filter on this car so I try to start the car for 10 times with engine trying to start (I’m so stupid sometimes) after this tries I looked on YouTube and educated myself and primed the diesel and the lc started with no problems.

I drived the car for 1 week after all o this approx 200 miles and
after that the issues start to appear…starts and cuts out in 1 second just cut out in middle of junction waited there for AA meanwhile I started to look around for issues disconnected the batteries that didn’t work, disconnected all the plugs from fuel filter and Maf sensor that didn’t work either at one point the car started from no where and I drive it home with no issues . Next day try to start the car same problem stars and cuts out after one sec called the aa again and this time they arrived but unfortunately didn’t find out what is it on tester is no issues at all just said is someting regarding to diesel..anyway.
one mobile mechanic changed the scv valve that didn’t work and look like it make it worse..when I spin the key the engine looks like is trying to spin after 1 or2 seconds but before doesn’t have that lag.
Also I changed again the fuel filter.

Now after all of this I’m looking for an specialised Toyota mechanic or Land Cruiser specialist or someone with fuel circulation knowledge I’m based in Hertfordshire and looking something around or a mobile mechanic.

First video is when it let me down first time and second video is after I changed the scv valve.

Land Cruiser 120 Prado, 3.0 diesel, 05’

Sorry for my bad English and thank you in advance.

Have you checked the prime pump button goes hard after a few presses if not your diafram is split . you say you have changed the SCV , did you make sure no dirt or debris entered the injection pump by cleaning the whole area with compressed air before removing the old SCV . What kind of new SCV have you fitted long or short because you need the long replacement SCV for the 1KD   , replacement short SCV are no good for the 1KD and are no longer made by denso for the 1KD so if its a short SCV saying its made by Denso  its likely to be a  counterfeit copy or a Denso one that is made that is still used on makes like Mitsubishi or nissan etc that still use the short ones that do not work on the 1KD . same goes with changing the fuel filter make sure no dirt or debris enters the fuel injection pump just as the with changing the SCV or it will give you endless problems .

Yes it has a pump in the fuel tank but are not known to fail unless the tank has run dry and you keep trying to start the car as the pump is lubed by fuel so if no fuel in the tank will burn out the pump . I feel pretty sure if you change the SCV to the long one and no dirt enters the injection pump you will solve your problem .

If your car ran OK for a week after you primed it after changing the fuel filter I do not think its a air lock , your symtoms are very much point to SCV problems . If you have fitted the wrong SCV for your car it needs to be rectified . My money is on the SCV  because if you hold up a litre of fuel to gravity  feed into the injection pump and after multiple tries of trying to start the engine and it did not start also points to the SCV or at the very worst but I doubt it the injection pump itself .

Have you checked the fuel pump 25 amp fuse ( number 29 on my car ) in the engine bay to see if it is not blown .

Hi Tony!

Hmmm... fuse 29 on mine is marked as 'Drivers power window' - and is 20 amp!

Struggling to find the fuel pump fuse... also... do you have a fuel pump relay?  I can't find that either!!!!

Cheers mate

Hi Karl fuse 29 in my engine bay fuse box is the forth fuse down after the 80 amp glow plug fuse if you do not count the empty fuse space and  the 80 amp glow plug fuse it is marked EFI on the fuse box lid which covers the petrol engine injectors but on the diesel it covers the fuel tank fuel pump as in the owners handbook it says fuse 29 is 25 amp on the 1kd and 20 amp on the petrol it is the fuel pump on the 1KD diesel . I do not have a fuel pump relay even though one is listed on the fuse box lid , most likely the fuel pump relay would be for the petrol engine .

[TONYCY11]

Fuse 30 on mine is listed as the dr front power window which is 20 amp

[TONYCY11]

First fuse after the 80amp glow plug fuse on mine is number is listed as number 32 which is 30amp and is radio no.2  audio system and navigation system ,
No.31 is Dr/lock 25 amp
No.30 is Dr fr p/w 20 amp
No.29 EFI 20amp petrol 1gr-fe engine multi port fuel injection system .and 25 amp 1kd-ftv diesel electronically controlled fuel pump .
