Standard Ignition RY-277 Fuel Pump Relay

Fuel Pump Relay for Mazda and Ford Applications

Standard Ignition RY-277 is a 12-volt fuel pump relay built for air and fuel delivery systems that need consistent electrical switching. It is a direct-fit style relay for select Mazda and Ford vehicles, including Mazda Millenia, Probe, 626, MX-6, 929, and RX-7 applications.

Key Features

• 12-volt fuel pump relay for engine fuel delivery control
• 20 amp amperage rating for relay circuit operation
• Female connector with square shape for vehicle-specific fitment
• 4 male blade terminals for electrical connection
• Composite housing helps protect against high under-hood temperatures
• Brass or copper contacts are used where specified for wear resistance
• Manufactured under TS16949 and ISO9001 certified quality systems

Detailed Description

Standard Ignition RY-277 is engineered as a replacement fuel pump relay for vehicles that rely on a stable relay signal to power the fuel pump circuit. The relay uses a 1-connector, 4-terminal blade design with a female square connector configuration, making it a practical choice for service on older Mazda and Ford platforms. This part cross-references Gates 19293 for the same application. Standard Ignition RY-277 is a fitment-focused replacement for 1995-2002 Mazda Millenia, 1993-1997 Ford Probe, 1993-1997 Mazda 626, 1993-1997 Mazda MX-6, 1988-1995 Mazda 929, and 1993-1995 Mazda RX-7.

What It Helps Fix

• Fuel pump not receiving power
• Intermittent engine start or no-start condition
• Relay clicking without consistent fuel pump operation
• Electrical switching issues in the fuel delivery circuit
• Hard starting caused by relay contact wear

Installation Notes and Tips

Verify connector shape, terminal count, amperage rating, and voltage before installation. Compare the original relay layout to the vehicle’s existing fuel pump relay location and confirm the part number RY-277 matches the required application. For best results, inspect the relay socket and terminals for heat damage, corrosion, or looseness before installing the replacement.

Quality Assurance

Standard Ignition manufactures this relay under controlled quality processes with TS16949 and ISO9001 certified plants. Composite housing construction and specified metal contacts support durability in demanding under-hood conditions.
