The Glow Plug Relay is a common failure point on the 7.3 Powerstroke diesel engine. My 2002 Ford F250 has suffered a GPR failure and in this video, I will show you how to test it AND replace it! The Glow Plug Relay is critical to starting a diesel engine during cold weather, as it sends power to your glow plugs in order to heat up the engine cylinders.
