Restore Instant Fuel Pump Priming & Stop Stalling: Genuine Honda/Acura Relay
Eliminate endless engine cranking, sudden highway stalling, and frustrating hot-start electrical failures. This Genuine Honda & Acura OEM Fuel Pump Relay Assembly (Part Number 39794-SDA-004) is the authentic factory electrical switch engineered explicitly for over 1,100 Honda and Acura car, truck, and SUV applications . Operating your vehicle with a degraded or heat-damaged main relay starves your engine of fuel pressure, leaving you stranded or causing intermittent engine cutouts under load.
Instead of risking sudden electrical failure with cheap aftermarket relays that use thin copper contacts, loose terminal pins, or poor housing plastic, installing this authentic factory component guarantees exact electrical resistance and current handling. Precision-manufactured to strict Honda factory standards, this 4-pin micro-relay delivers clean, instant power routing directly to your fuel pump and engine management circuits.
This authentic factory component directly replaces and supersedes prior Honda/Acura part number 39794-SDA-305 .
Why This Genuine Honda/Acura 39794-SDA-004 OEM Relay is the Professional Choice:
Factory-Specified Current Capacity: Engineered with heavy-duty internal contact points designed to handle high inductive electrical loads without contact arc-welding or sticking.
Direct Plug-and-Play 4-Pin Fitment: Features factory-correct blade terminal pin layout and latching tabs to plug directly into under-hood or under-dash fuse/relay boxes.
Thermal & Vibration Resistance: Housed in a heat-stabilized composite shell built to withstand intense engine bay temperatures and continuous road vibration.

🛠️ Pro-Maintenance Tip: Watch the "Fuse Box Relay Swap & Fuel Pump Sound Secret!" Shop Service Secret: When diagnosing a no-start issue on an Accord or TL, turn the ignition key to the "ON" position (without cranking) and listen closely near the rear seat or fuel tank. You should hear the fuel pump hum for 2 seconds to prime the system. If you hear silence, locate the fuel pump relay in the fuse box and test it by swapping it temporarily with an identical non-critical relay (like the horn or rear defrost relay). Installation Secret: Always apply a tiny drop of dielectric grease onto the relay blade pins before pressing it firmly into the fuse box socket to seal out moisture and corrosion.
