1 Other Fuel System Pump problem

Failure Date: 02/13/2026

While driving at highway speeds, a warning light appeared as well as an alert indicating the car was limited to no more than 4000rpm. After coming to a stop, a strong smell of gasoline was noticed in the passenger compartment. Continued driving home uneventfully but the strong smell of gas persisted. The next day I drove the car to a mechanic. Their inspection notes the following: the technician verified the customer concern of a fuel smell. He performed a fault scan, finding codes for low fuel pressure. He inspected the vehicle, finding a major fuel leak under the intake manifold, most likely from a cracked fuel rail. The system is supposed to operate at 125 bar of fuel pressure, but is currently at 9-11 bar. The high pressure fuel pump is operating at 100% duty cycle, which means it has overheated and been damaged. Metal shavings from the fuel pump then ends up inside of the injectors, ruining them. The low pressure fuel pump may be ok, but it is unclear at this time. **recommend replacing fuel rail, high pressure fuel pump, injectors with seals, and pressure sensor * need low pressure fuel pump they also noted that the leaking fuel could cause a fire hazard. The fact that this fuel leak happened at only 98,750 miles and that the car continued to be drivable with fuel spraying all over the engine compartment is extremely concerning.
