Checking and replacing the Toyota Corolla fuel pressure regulator

Tools:

• Screwdriver flat medium

Parts and consumables:

• Cloth gloves
• rags
• Fuel pressure control

Note:

The fuel pressure regulator is installed in the fuel pump module. The correctness of the regulator is determined on a running engine by the fuel pressure in the injector rail (see "Checking the pressure in the engine power system"). If the pressure is below normal, and the rest of the system is working, the regulator is faulty.
