Send electrical power where it is needed with the Standard Ignition Fuel Pump Relay / Starter Relay RY-1678, an electrical relay that uses a low-current control signal to switch a higher-current circuit. It fits many vehicles, among them the 1993-1998 Hyundai Sonata, 2008-2009 Isuzu NPR and 2008-2009 Isuzu NPR-HD, as a direct-fit replacement for the listed applications. See the "Vehicles it fits" section for the full list and engine details.
This part is cataloged under two names, fuel pump relay and starter relay, so you may see it listed either way. If a failed relay is the cause of a no-start, a fuel pump that won't run or a starter that won't engage, this unit replaces it. Diagnose the circuit before replacing, since wiring, fuses and other components can cause the same symptoms.
- Built for under-hood use: Standard Ignition's relays use high-quality composite housings designed to stand up to harsh temperatures and demanding under-hood conditions.
- Certified manufacturing: Made at TS16949 and ISO9001 certified facilities.
- OE ignition background: Standard Ignition is a global manufacturer of original equipment ignition products and maintains quality control throughout the manufacturing process, from componentry to finished product.
