Toyota Prado 2009 diesel intermittently stalls when idlying once heated up

2009 Prado diesel(auto) running fine but in past month problem of intermittent stalling when idlying. Only occurs intermittently and after a reasonable run and engine is heated up - pull up at lights and whilst idlying will simply stall. Vehicle will restart without fuss and then drives ok for days/week before the problem recurs under the same circumstances described. Fuel filters and accelerator pedal replaced but problem remains?? Nothing evident when dealer uses diagnostic equipment on vehicle and unfortunately the problem has not occured when they road test with diagnostic equipment?? A sensor or something?? Going around in circles and driving me crazy!!

SOUNDS LIKE THE FIRST STAGES OF AN ELECTRIC FUEL PUMP FAILING. THEY ARE NOTORIOUS FOR THESE TYPES OF SYMPTOMS. THE LOW PRESSURE AT THE TRAFFIC LIGHT RESULTS IN THE STALL, BUT AS LONG AS ITS UNDER DEMAND IT WILL FUNCTION OK UNTIL IT QQUITS. HAVE A PRESSURE CHECK DONE ON THE FUEL PUMP

My 2011 iload Diesel Turbo Auto is having a stalling issue.


same problem indicated on an isuzu diesel that turned out to be problem injector causing the ECM to shut down and then allow a restart-- no codes shown and the service center was stumped until a diesel repair shop checked it out and found an injector control was faulty
check for vent problem in the fuel tank starving the diesel for fuel

Toyota Prado 2009 the fuel system warning light came on, the system has only had Caltex diesel through it, the filter was changed 15.000 K a go. I fix the problem?


the fuel system light could be low fuel level, vent problem or water in the fuel from condensation in the tank
take it in for a service check and code reading

What could cause a 2003 prado diesel blowing ig1 no2 fuse intermittantly?


My suspicion is a faulty relay, but it's just a hunch because of how it's behaving. I assume that once it's running if you put a fuse in it doesn't blow?
Find the relay for the aircon as that's the most likely candidate and remove it, see if it still happens. If it does not cure it you will have to try to isolate each circuit supplied by that fuse one at a time.
Whatever is causing the surge is only happening when the circuit is energised or de-energised by the ignition, but presumably everything is working OK?

Please make sure earth/ground points are tight and free of dirt and corrosion. especially knowing this is off road car. fuses are clean. charge relay is working correctly, main fuse CONNECTIONS are good. the fact that it happens when you move , means most likely a loose connection.

Make sure you have genuine filters. Mine was doing exactly the same thing after a service - had a non genuine filter fitted - as soon as the genuine one went back on hasn't done it since...
