2019 Toyota Tundra fuel system problems

Filed Sep 28, 2026 · Fuel system · AR

The fuel pump and the fuel pump control module system failed. Before the failure, I drove my 2019 Toyota Tundra on XXX from [XXX] to [XXX] with no prior check engine light warning. It was parked for all 3 days at a campground in [XXX]. However, on XXX the vehicle would not start. The truck ignition was moved to the RUN position and then the check engine light came on, which was the first notification of a potential problem. So, I attempted to start the vehicle, there was a crank but not a start incident. The ignition was moved back to the OFF position. I'm also an experienced mechanic, so I lifted the hood to diagnose the issue and search where the malfunction was occurring. I inspected the battery, all the fuses, the relays controlling the fuel pump, and the fuel pump control module. Using a Voltmeter Tester, the battery had a full charge. The relays and the fuses were also replaced with no success in starting the vehicle. The fuel line was disconnected from the fuel rail so I could verify if fuel was getting to the engine. The truck ignition was again moved to the RUN position and then the Start Position with NO success of fuel getting to the fuel rail. The vehicle was then towed to a local auto shop and the problem has been reproduced only by Crawford Auto Repair shop in [XXX]. The auto mechanic mentioned two error codes were presented: 1. The fuel pump 2. The fuel pump control module. Thankfully, there was no immediate risk to my family's safety but it could have occurred while driving back through the [XXX] mountains on our way home.

We had just exited the interstate when my Toyota Tundra stopped. We had it towed to the closest Toyota dealer. We had to have fuel pump replaced. They said the previous year Tundra was recalled for this issue, but ours was not. I just found out that some of the 2019 models had been recalled for this issue. They said my VIN was not recalled. That does not make sense. It was the same problem, same year, just at a different plant. Now we are having other fuel issues and the dealer says it all stems from the replacement of the pump, which we had to pay out of pocket. If we had not just exited the interstate it could have caused a major accident.

When refueling this vehicle, gasoline will flow out of the filler tank onto the ground and will shoot out onto the person filling the truck up. Have had the charcoal canister replaced twice and this has not fixed the problem for any length of time. Dealer claims that vent tubes are getting clogged up but cannot explain how or why they are plugged up. Last repair lasted one week before fueling issues showed up again. The gas shooting out of the filler hose onto people standing nearby and onto the ground is an extreme fire and explosion issue and is an environmental issue. This problem seems to be a common issue based on internet search for Toyota Tundra refueling issues. There has been a service bulletin published by Toyota on this issue. I have been having this problem for over 2 years.
