Detailed Description

Standard Ignition PR9 is built for gasoline fuel systems and is used to regulate fuel pressure within the injection system. Proper pressure control is important for starting, idle quality, throttle response, and overall fuel delivery consistency. This part fits 1979-1985 Toyota Celica, 1980-1987 Toyota Cressida, and 1988 Toyota Cressida with tilt steering wheel noted in the fitment data. If you are replacing a worn Toyota Cressida fuel injection pressure regulator or servicing a Toyota Celica EFI system, PR9 provides a direct replacement option under the Standard Ignition part number PR9.

Common Issues This Part Can Address

• Fuel pressure that is too high or too low at the rail
• Hard starting or extended crank time
• Rough idle or unstable engine operation
