Engine shuts off randomly after applying throttle, regardless of speed.

Hello!

We have a LandCruiser J100 series from 2000, it comes with an HDJ-FTE engine. The engine would randomly stop at any speed. In a 3 hour trip, it probably stopped around 6 times. Turning the ignition and not giving much throttle starts the engine again at speed. At first, we had the check engine light running at all times. We ran it through diagnostics and the problems we found were the "Intake shutter control circuit" had a fault somewhere, we tested all the VSV Solenoids and saw that two were out of range in resistance, we replaced these. The constant check engine light is gone! However, the engine stopping still continued. We can leave the car in neutral, give it max throttle, and the engine. We have been able to stall it every time by giving it maximum throttle. After replacing the out of range VSV's the check engine light only goes on briefly when the engine shuts off, then when we turn the ignition it goes back off.

My hypothesis is that the out of range VSV's never was a problem, but just caused the constant engine light, instead, the real problem could lie somewhere inside the accelerator position sensor. I have no clue however, how this system works. It doesn't even look like the throttle body is controlled by a motor :sweatsmile:

Would love to hear some input or if anyone has experienced a similar problem.

Thanks, guys!
 
Most common reason for random stopping on a 2000 hdj-fte is bad connection on the cable/plug between the SCV (spill valve) and the EDU supplying it. But this sounds more like fuel delivery, e.g. wrong filter or blocked tank filter (sieve/sock), if it comes whenever there is demand for more fuel. You could try with a bottle of fuel feeding directly into the injection pump, to circumvent both of those.
Could also be a blocked particulate filter on the exhaust. If that's the case you can sometimes hear it "whistle" because of the high air speed through the few open channels through it.
