Glow Plug Relay Buzzing after glow plug install
So I'm running a GPR109, and just replaced my glow plugs. I scored some used, cheap glow plugs, as I'm not sure how long I'll keep this truck. The plugs worked great, and installed easily.
7 of mine were not working.
After installing the passenger side bank of glow plugs, I tested the system, and noticed the GPR making a loud buzzing sound. It did not do this before. I haven't ever posted because most of my problems I can find with a search. Unfortunately I have found few similar problems...
Anyway, what do you think? The relay is only about 6 months old. Could it be bad? I tested it, it is kicking on properly.
