Detailed Product Description

The RY-564 relay from Standard Ignition is a computer control relay designed to regulate the fuel pump operation in compatible Volvo vehicles. With five male blade terminals arranged in a square connector shape, this relay ensures secure and reliable electrical connections. It operates at 12 volts with a 30 amp rating, suitable for the fuel pump's power requirements. This relay is not rated for continuous duty, indicating it is intended for intermittent operation consistent with fuel pump cycling. The absence of a mounting bracket means installation requires securing the relay in an appropriate location within the vehicle's relay panel or fuse box.

Common Applications and Issues Addressed

  • Replacement for faulty or worn fuel pump relays in Volvo 850, 940, 960, S40, and V40 models
  • Resolves intermittent fuel pump operation or failure to start issues
  • Addresses electrical faults causing fuel delivery interruptions
  • Helps eliminate engine stalling related to fuel pump relay malfunction
  • Prevents no-start conditions caused by relay failure

Installation Notes and Tips

  • Verify vehicle compatibility with Volvo 850, 940, 960, S40, or V40 before installation
  • Ensure the relay terminals match the vehicle’s wiring harness connector
  • Secure the relay firmly in the relay panel or fuse box; mounting bracket not included
  • Disconnect the battery before replacing the relay to avoid electrical shorts
  • Test the relay function after installation to confirm proper fuel pump operation

Quality Assurance and Warranty

Standard Ignition manufactures the RY-564 relay to meet OEM specifications for reliable performance in Volvo vehicles. While continuous duty operation is not supported, the relay is engineered for the intermittent cycling typical of fuel pump control. Warranty coverage details should be confirmed at the point of purchase, as Standard Ignition generally provides limited warranties covering defects in materials and workmanship.
