Where is the high-pressure fuel pump located in a Toyota Corolla?
1 Answers
Toyota Corolla's high-pressure fuel pump is located on top of the engine. Here are some relevant details about the high-pressure fuel pump: 1. Function: It draws fuel from the fuel tank, pressurizes it, and delivers it to the fuel supply line, working in conjunction with the fuel pressure regulator to establish a certain fuel pressure. 2. Purpose: The high-pressure fuel pump supplies pressurized fuel to the fuel rail, ensuring continuous fuel supply to the injectors. The high-pressure fuel pump operates during engine start and while the engine is running. If the engine stops but the ignition switch remains in the ON position, the HFM-SFI control module cuts power to the high-pressure fuel pump to prevent accidental ignition.
