Fuel pump failure at 63k miles. Check Engine light came on. P0171 code thrown. Truck began hard starting, and rough idling. Stalled on freeway, stuck at 4k RPM and would not drop. Had to pull off and restart. Checked entire system with certified independent service/AAA mechanic and fuel pump was diagnosed. Fuel pump whines in tank, and fuel trim levels are way off... maxing out in output (39), and falling into the negatives in short term trim levels. All other components testing ok/within ranges. Massive recall on fuel pump for my exact same year/make/model/engine, but my VIN does not show as affected... clearly it has the same issue. I need this pump fixed ASAP, as does everyone else affected that did not get to be apart of the recall.

Toyota sold this vehicle knowing of defective fuel pump - had issues day one with long crank cycles to start. Loud knocking of high pressure fuel pump reported also-probably related to low pressure fuel pump malfunction and cavitation at high pressure pump. I have also experienced rough idle and jerking. I contacted selling dealer in jan 2020 after recall with no remedy issued and they stated that there was only like 1 vehicle affected - outright lie. There is class action suit for this defect in progress and over 2000 pumps had failed and toyota knew about it. Other problems with vehicle including faulty differential and it took 4 visits and failed ncds claim for toyota to admit it was defective and replace only after 12,000 lemon law limit in kentucky. Toyota and its' dealers are cover up artists. Sitting here still with vehicle unsafe to drive with no fuel pump even after 10 months - final remedy came in on toyota owners website and called selling dealer and they said I had to go on waiting list for 2-3 weeks to even get the part - toyota should buy back this vehicle.

The subject vehicles are equipped with a low-pressure fuel pump which may stop operating. If this were to occur, warning lights and messages may be displayed on the instrument panel, and the engine may run rough. This may result in a vehicle stall, and the vehicle may be unable to be restarted. If a vehicle stall occurs while driving at higher speeds, this could increase the risk of a crash.
