Toyota 4RUNNER won't start problems

Filed Nov 6, 2026 · Fuel system · TX

My 2019 Toyota 4Runner would not start after I filled up with gas on 11/5/2026. The engine cranked but would not start and the vehicle had to be towed to a Toyota dealership. The symptoms match the low-pressure fuel pump failure in Toyota's Denso fuel pump recall. The call says this pump can fail while driving and cause the engine to stall which can cause a crash. Before towing, I contacted Toyota customer support and visited a dealership in person. Toyota customer support told me and emphasized that the repair would be covered and gave me a program number. The dealership also outlined (21TA02) in the estimate. After the vehicle had already been towed, the dealer declined coverage because of mileage and is charging me for diagnosis. I have opened a case with Toyota corporate and it has been escalated. I am asking the federal safety agency to review and support the replacement of the fuel pump for my vehicle. If diagnosis does not result in the fuel pump, I can cover the cost. If it is the fuel pump, I'd like to have the diagnostic fee waived and repairs completed.

Toyota 4 runner had a recall for the fuel pump. I have been having starting issues with it ever since. The power is good and the starter tries to turn the vehicle over. But the vehicle won't start. I have taken it to multiple locations for service through out the chicago land area. Also once the vehicle finally does start. The R.P.M.s will suddenly increase and decrease to the point that the vehicle turns off while in drive. I can provide print outs when the vehicle gets fixed, if ever. I purchased the vehicle as CPO.

I own a 2014 toyota 4runner ltd. I also own a 2011 toyota 4runner ltd. One vehicle is driven by myself, and the other is driven by my spouse. Each vehicle has its own key fob with push button start. When my spouse is traveling with me in the passenger seat of my vehicle, my key fob is not recognized, warning lights are displayed on my console and my vehicle does not start. My vehicle will start at times when I place my key fob next to the push to start button or request my spouse to stay outside my vehicle. However, when traveling with me, the warning lights are on and will prevent a startup in the case of an emergency. The same thing happens when I am travelling as a passenger in her vehicle (the 2011 toyota 4runner).

Recall: structure of truck. I have 2003 toyota 4 runner that is rusting real bad. The structure frame is loosing a lot of rust . I have even have at least 3 wholes in my passenger side frame under my truck. I see many other people are having this issue. I would like to see someone look into to see why this is happening and take action because I feel this will become a serous safety issue to people who are having this issue with the structure rusting of the truck. I just had my vehicle at the dealer for warranty work and nothing was noted on the final checkout paper work about the serous issue with the rust. My vehicle is driven for daily use no off tossing or crazy activities with my vehicle. We even wash our vehicle regularly doing the winter months.... I see they have did a structure recall to ( toyota tacoma, tundras, and sequios. I am really surprised how this is happening to tony vehicle. Please note this has been a issue for awhile with the truck with rusting it just did not start .

Since I got the car, the ignition key does not get in properly and sometimes does not start the car. The movement of the wheel helps sometimes. There have also been leaking engine covers that needed to be replaced. The structure gets rusty and there is problem with transmission.

My 2002 4runner was purchased brand new from toyota in november of 2001. I live in new york so it does snow 2 or 3 months out of the year. It has been used as a second vehicle to pick up supplies and the like, otherwise it is rarely used. At this time it has approx. 139000 miles. The truck would not start and I took it to a mechanic. I was told there is an extreme amount of rust under the vehicle, the undercarriage, the frame, the gas tank, etc. The problem is the fuel pump but because of so much rust, removing the gas tank to change the fuel pump may cause damage to the components connecting the tank to the frame of the vehicle. It is a shame that toyota sells a vehicle that may need to be junked due to the amount of rust it has. I understand that many other owners have the same problem with the 4runner and something should be done. I bought a 1999 camry brand new prior to the 4runner and I had it for 12 years before giving it to a friend who still drives it to this day and it has no rust. The 4runner runs great all of the years I have owned it but I am being told by my mechanic that it is possible the body of my truck could fall from the frame. At 139000 miles this should not be happening. Toyota should offer some kind of repair to these issues. My truck looks almost brand new except for some rust on the front and rear bumpers and now I may have to junk it.

My 2000 4runner engine broke down on the highway, it started making a loud clanking noise and we pulled over and it died and wouldn't start again , we had to gave it towed home and the mechanic informed us after replacing the starter , alternator and battery that it needed a new engine. We have always kept up with oil changes and tune ups so this was a shook to us. We will be contacting toyota to see what is going on with these 2000 4runners since I have read that many consumers are having the same problem.
