2019 Toyota Tundra: check engine light

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.

Driving with cruise control at 30 MPH, the engine light turned on , and suddenly the engine shut down, no brakes and no power steering. I went to turn right at the nearest available side street so I would get out of the way of traffic. As I was trying to turn right, the steering wheel was very hard to turn and I ended up on the wrong side of road and impeding traffic. Luckily the road was slightly uphill and the truck was able to come to a stop. I then applied the emergency brake and turned the key to the off position. I tried restarting the truck to get it out of the opposite side of the road and at that time it cranked and it had a stalled rubble sound for about 3 seconds and then shut down again. At some point the transmission became locked and the tow truck driver had to use the shift lock release to get it on the flatbed.
