Review on 🔌 Enhanced Performance Relay - Standard Motor Products RY-1556 by Mike Starling

2004.5 Duramax LLY 240782 miles. OBD code P0671 is on. I reset the code a few times, as soon as I started the car the light came back on. I checked the batteries and wiring harness for shorts and everything was ok so I ordered this relay from Amazon. The glow plug relay arrived a few days later and it took me just 15 minutes along the way to replace it with a 10mm head, 3 extensions and a ratchet by removing the 2 screws holding it in place. I then reset the engine light and the alt issue was resolved. I have driven the truck about 350 miles since installing the new relay and the engine will not start. Everything works as it should, now the glow plugs work again. This relay is the perfect replacement connector, it's the same design as the original OEM relay I've seen and works great.
